Dear Colleagues,
When running FreeBSD as an IPv6 host im SLAAC mode, is
"rtsold_enable=YES" really necessary? I did not enable rtsold and IPv6
still works fine only with
fconfig_re0=""
ifconfig_re0_ipv6="inet6 accept_rtadv"
What would be the point of enabling rtsold then?

The router may send a router advertisement whenever it wants. That's why
your machine seems to work even without rtsold. However, SLAAC addresses
expire after a certain amount of time. rtsold will ask the router for a
new advertisement before your address expires. You aren't guaranteed to
have problems if you don't run rtsold, but you aren't guaranteed not to
have problems if you don't. Best to let it run.

I see the point but who on earth sent the initial router solicitation
on boot if I never enabled rtsold?
I have not found rtsold in /etc/rc.d/netif or similar startup script.

--- Comment #12 from Lev A. Serebryakov <lev@FreeBSD.org> ---
Ok. Now I have kernel with INVARIANTs and WITNESS and I have space fro
crashdumps.
I've got 3 crashdumps with exactly same panic message:
Assertion (staterr & E1000_RXD_STAT_DD) !=3D 0 failed at

Indeed, it's called from /etc/network.subr if rtsold is NOT enabled.

--- Comment #13 from Lev A. Serebryakov <lev@FreeBSD.org> ---
Without debug options in kernel crashes are all different, but it is always
GPE. Looks like memory corruption.
Please note, that without SAD/SDP everything works. And with "null" SAD
everything works for hours.
Even sending works with IPsec and aes-256-gcm/aes-256-cbc. Only combination=
of
IPsec with true encryption and receiving data leads to crash.

I have all crashdumps saved, and I have corresponding kernel.full saved, to=

so I could provide any additional information which could be extracted with

--- Comment #11 from Cy Schubert <cy@FreeBSD.org> ---
(In reply to NK from comment #10)
Sketchy details. There's nothing to go on.
The WOL patch was developed for 12-CURRENT only. The only issue is a system
will not halt -p after being woken by WOL, but will after a reboot.
I'll try to port it back to 11-STABLE if anyone is interested.

A commit references this bug:
Author: ae
Date: Mon Oct 1 10:46:01 UTC 2018
New revision: 339039
URL: https://svnweb.freebsd.org/changeset/base/339039
Log:
Add INP_INFO_WUNLOCK_ASSERT() macro and use it instead of
INP_INFO_UNLOCK_ASSERT() in TCP-related code. For encapsulated traffic
it is possible, that the code is running in net_epoch_preempt section,
and INP_INFO_UNLOCK_ASSERT() is very strict assertion for such case.

WOL patch for stable/11
Same patch, for stable/11. I haven't tried to build or use this particular
patch on stable/11. However a previous version was developed for current/11=
at
the time. This patch has the same problem as the -CURRENT patch, the system
will reboot on halt -p the first time around. I'm not sure of the solution =
for
this yet.

--- Comment #6 from Stephen Hurd <shurd@FreeBSD.org> ---
The packet captures are consistent with the checksum being calculated with =
the
pseudo header having the correct checksum, not zero. Forcing the UDP check=
sum
to zero before passing to the card would likely work around the issue, but I
want to figure out what changed to cause this issue to crop up first.

A commit references this bug:
Author: glebius
Date: Wed Oct 3 17:40:05 UTC 2018
New revision: 339170
URL: https://svnweb.freebsd.org/changeset/base/339170
Log:
In PR 227259, a user is reporting that they have code which is using
shutdown() to wakeup another thread blocked on a stream listen socket.
This code is failing, while it used to work on FreeBSD 10 and still
works on Linux.
It seems reasonable to add another exception to support something users a=
re
actually doing, which used to work on FreeBSD 10, and still works on Linu=
x.
And, it seems like it should be acceptable to POSIX, as we still return
ENOTCONN.
This patch is different to what had been committed to stable/11, since
code around listening sockets is different. Patch in D15019 is written
by jtl@, slightly modified by me.

--- Comment #7 from Stephen Hurd <shurd@FreeBSD.org> ---
Can you test with the patch in the review here:
https://reviews.freebsd.org/D17393
I'm not confident this will fix the problem, but it's the only obvious issu=
e I
saw tracing the send path:
bpf.c:bpfwrite()
if_ethersubr.c:ether_output()
if_ethersubr.c:ether_output_frame()
if_vlan.c:vlan_transmit()
iflib.c:iflib_if_transmit()
...
igb_txrx.c:igb_isc_txd_encap()
igb_txrx.c:igb_tx_ctx_setup()
If this fixes the issue, the bce(4) issue is a different issue.

--- Comment #8 from Eric van Gyzen <vangyzen@FreeBSD.org> ---
I'll test it in the next day or two. I think I can only test it on my home
firewall, so I have to schedule downtime with the family. ;)
I would be grateful if other people tested it, too.

Nope. It make worse.
I've explained problems with more details ant phabricator.
I don't noow, should we duplicate all comments in two places?

(In reply to Lev A. Serebryakov from comment #10)
I think that comments regarding the patch can/should go on Phabricator only=
and
comments about the bug should go here (and likely not on Phabricator).

FCP-01010 (https://github.com/freebsd/fcp/blob/master/fcp-0101.md)
outlines a plan to deprecate most 10/100 Ethernet drivers in FreeBSD 12
and remove them in FreeBSD 13 to reduce the burden of maintaining and
improving the network stack. We have discussed this within the
core team and intend to move forward as proposed. We are solictiting
feedback on the list of drivers to be excepted from removal.
The current list of drivers slated for REMOVAL is:
ae, bfe, bm, cs, dme, ed, ep, ex, fe, pcn, rl, sf, smc, sn,
ste, tl, tx, txp, vx, wb, xe
The current list of drivers that will STAY in the tree is:
dc, ffec, fxpl, hme, le, sis, vr, xl
The criteria for exception are:
- Popular in applications where it is likely to be deployed beyond the
support lifetime of FreeBSD 12 (late 2023).
- 5 reports of uses in the wild on machines running FreeBSD 12 will be
deemed satisfy the "popular"
requirement.
- Required to make a well supported embedded or emulation platform usable.
- Ported to use iflib (reducing future maintenance cost.)
Please reply to this message with nominations to the exception list.
The full FCP-0101 is included below.

# FCP 101: Deprecation and removal of 10/100 Ethernet drivers
Deprecate most 10 and 10/100Mbps Ethernet drivers and remove them before
FreeBSD 13.
## Problem Statement
Each network driver creates drag for the project as we attempt to
improve the network stack or provide new features such as expanded
32-bit compatibility. For example, the author has edited every single
NIC driver more than once in the past year to update management (`ioctl`)
interfaces. We could improve this situation by converting drivers to
iflib, but each additional driver takes work.
10 and 100 megabit Ethernet drivers are largely irrelevant today
and we have a significant number of them in the tree. The ones that
are no longer used and/or are not known to be working need to be
removed due to the significant ongoing 'tax' on new development.
For at least a decade, most systems (including small embedded
systems) have shipped with gigabit Ethernet devices and virtual
machines commonly emulate popular gigabit devices. We wish to
retain support for popular physical and virtual devices while
removing support for uncommon ones. With a few exceptions these
drivers are unlikely to be used by our user base by the time FreeBSD
12 is obsolete (approximately 2024).
## Proposed Solution
We propose to deprecate devices which are not sufficiently popular. This
will entail:
- (October 2018) Send this list to freebsd-net and freebsd-stable.
- (Before FreeBSD 12.0-RELEASE - October 2018) Update the manpages and
attach routines for each device to be removed and merge those changes
to FreeBSD 12.
- (One month after FreeBSD 12.0-RELEASE - January 2018) Remind
freebsd-net and freebsd-stable users of pending deletion.
- (Two months after FreeBSD 12.0-RELEASE - February 2019) Delete deprecated
devices.
Through out this process, solicit feedback on additions to the exception
list and update this document as required. For a device to be placed on
the exception list the device must meet one of the following criteria:
- Popular in applications where it is likely to be deployed beyond the
support lifetime of FreeBSD 12 (late 2023).
- 5 reports of uses in the wild on machines running FreeBSD 12 will be
deemed satisfy the "popular"
requirement.
- Required to make a well supported embedded or emulation platform usable.
- Ported to use iflib (reducing future maintenance cost.)
### Exceptions to removal
Device | Reason
-------|-------------------------------------------------
ffec | Onboard Ethernet for Vybrid arm7 boards
fxp | Popular device long recommended by the project.
dc | Popular device for CardBus card.
hme | Built in interface on many supported sparc64 platforms.
le | Emulated by QEMU, alternatives don't yet work for mips64.
sis | Soekris Engineering net45xx, net48xx, lan1621, and lan1641.
vr | Soekris Engineering net5501, some Asus motherboards.
xl | Popular device for CardBus card.
Note: USB devices have been excluded from consideration in this round.
### Device to be removed
ae, bfe, bm, cs, dme, ed, ep, ex, fe, pcn, rl, sf, smc, sn,
ste, tl, tx, txp, vx, wb, xe
## Final Disposition
TBD

The documentation with respect to naming is wrong. I didn't have a bit

"fxpl" should have been "fxp" here, I suppose.
While I have no objection for general direction, I have doubts about removal of ste(4) and especially rl(4).
These are cheap 100Mbit VERY popular NICs sold in enourmous values in certain markets
by vendors like D-Link and TP-Link using various trade names.
Lack of support for such popular 100M cards won't be good for FreeBSD, I suppose.

Hi,
I fixed this upstream in this commit
https://github.com/luigirizzo/netmap/commit/282f404ccb4fc777056a591127060e29657c9ab7
I will apply the change into FreeBSD as soon as HEAD thaws.
Cheers,
Vincenzo

Holy shit! OK I guess I can understand removing 10 (I personally haven't
seen one in a very long time) but 100 are omnipresent and most of my NICs
are in fact 100.

Looking at the commits they require near zero maintenance. What exactly
is the burden here? Another question: why the fuck FreeBSD likes to kill
non-broken, low-volatile and perfectly working stuff? We offer probably
the best NIC driver support on the block, yet you're proposing to shrink
one of the few areas where we shine. WTF?!

ae(4) was used in Asus EeePC 701/900 which are still popular among hackers.
My home router uses sf(4) happily. It's a dual-port card and I don't want
to look for expensive and completely needless replacement. Other people
have already told you about ed/rl/etc.

As it can be seen this list tends to cover nearly all 100 cards, yet no
one (pardon me if I missed those) asks for 10. So how about making this
proposal cover only 10 cards, if you can't resist the itch to remove
something from the tree?

Sill using my Asus EeePC 701 (just bought a new battery pack) for
FreeBSD with ae nic (and I do not foresee discontinuing its use any time
soon as its serial port comes in handy for talking to other serial devices).

Please do not remove rl. I have two rl interfaces in a machine built in
2011 still in daily use. One rl interface is an aftermarket card bought
new in *2016*. The other one is built into the motherboard. That's just
the stuff I personally own. rl is in lots of machines which will
probably still be running a decade from now.
I'm astonished you're considering removing rl given how common it is.

Don't panic - they're talking about removing the 100 MBps NICS, not
the 100 GBps NICs.
Jokes aside - obviously there are very different populations of NICS.
Here, the only 100MBps interface is in the IP phone, and I would guess
that even most consumer hardware comes with a GBps interface on board
(heck, even RPis have a GBit interface, even if can't use more than 30%
of it's bandwith). Checking with a hardware-dealer: very few NICs in
their catalog are 100MBps, most are gigabit-grade.
I would have expected that things look different in the embedded world...
On the other hand, some data centers I know routinely use 10GBps, and
1 GBps is considered "legacy" there.
So, perceptions are very different... let's keep this rational and
make a list of cards still in use.
Regards,
Christoph

I also call for keeping of the ste(4) driver.
We use several 4-head D-Link DFE-580TX cards. Removing their support would =
incur serious expenses for us for replacement hardware.

Only the 3B.
Older models, up to the first RPi3 still have a 100Mb/s NIC.
I just happen to have an RPi3 and I'd really love to convert it to
FreeBSD once 12.x is stable enough.
BTW, I also use fxp interfaces a lot, but that's just because I have
several of them around: no use spending a few Euros for faster cards if
they are going to be used for ADSL lines.
Then I have an old "hot-spare" computer that has an onboard FastEthernet
NIC... I'll have to check which one it is and if support for it is being
dropped.
Or... I could insert another spare fxp there too :)
Seriously, I'd be disappointed if the yet-to-come-to-stable support for
my Raspberry was deprivated of its NIC driver.
Other than that, on the amd64 side, I'll live with this (if I have to).

I have a lot of them in production systems. It would be a pity that they
will never get a 12.x or newer version ever. I can replace few de cards
but not everything...

To be clear, the proposal is that 12.x be the last branch they are
supported in and not in 13. So while we'd remove them from current soon,
they'd still be in 12 for the life of the 12.x branch, so into the early
2020's.

I believe that characterization is incorrect. There's a burden. And it's
death of a thousand cuts. And many of those cuts have been inflicted on
brooks@.
Most of these drivers have had dozens or hundreds of commits each over the
years to keep up with the API changes. This acts as a tax on innovation
because it's such a pain in the back side to change all the drivers in the
tree. I did a back of the envelope computation that this is on the order of
hundreds of hours of time, spread across all the drivers over all the years
we've supported them. Some of these drivers are clearly unused, and so
that's 100% wasted effort. Most of these drivers are on machines that most
likely won't be able to run 13.0 well when it comes out in 2 years due to
increased memory demands that it will almost certainly have. The declining
use means we anticipate that if we were to maintain them until 13, it would
be wasted effort for at least some on the list.
That's why that one way to get the driver off the list is to convert to
iflib. That greatly reduces the burden by centralizing all the stupid,
common things of a driver so that we only have to change one place, not
dozens.
At the root of this problem is the community's long resistance to having
data reported back to the project data about the machines running FreeBSD.
Absent any real and significant data, the only way to know if things are
unused is to ask. We cannot have the act of merely asking cause people to
freak out and hurl expletives all over the place. That's significantly not
cool.

As one who has been there, a couple of times: SECONDED!
It is particular unpleasant when you have no way to test the changes.

Sigh. If you really plan to still be using i386 and 10/100 ether in
2024, perhaps you should consider NetBSD.
You can buy used core i5 laptops for around $20 if you shop around.

I can probably do this for bfe and fxp, since I have both.
Can someone suggest a good example driver that has already been converted,
so I can see what needs to be done?
Again, I don't care if they stay in the current/head tree.

I don't quite understand why are you grouping 10/100 vs. 1000 rather than
10 vs. 100/1000.

As far as I know, none of the drivers listed could do 1Gbps. They were all
specifically 10Mbps or 10/100Mbps. Support for 10Mbps or 100Mbps isn't
being removed from the tree: there's still dozens of GigE drivers that can
do those speeds that have PCI or better bus attachments.

Right. My point was that original proposal put 10/100 drivers into one
basket, which is IMHO not fair: 10Mbps cards are rarely seen and used,
100mbps are not, just like 1000bps ones.
That said, I'm okay with deorbiting NICs that cannot do more than 10mbps.
Cards that can do at least 100mbps should stay. Following up on Ricks'
question, seeing a good example of modernization a certain driver would
help interested people/hw owners to keep drivers for their cards viable.

I can probably do this for bfe and fxp, since I have both.
Can someone suggest a good example driver that has already been converted,

People need to submit patches then. OTOH, they can all be moved to ports. I=
MO, when pkgbase becomes a reality, much of this will become moot. People w=
ill be able to mix and match base and ports packages.

Right. My point was that original proposal put 10/100 drivers into one
basket, which is IMHO not fair: 10Mbps cards are rarely seen and used,
100mbps are not, just like 1000bps ones.
That said, I'm okay with deorbiting NICs that cannot do more than 10mbps.
Cards that can do at least 100mbps should stay. Following up on Ricks'
question, seeing a good example of modernization a certain driver would
help interested people/hw owners to keep drivers for their cards viable.

All commits, no matter how trivial, require re@ approval. That necessarily
slows things down, hence my phrase "as quickly as the freeze allows."

Absent good data, one has to make one's best guesses. I guessed wrong here
in my comments to Brooks about which ones were must keeps. I knew it was
popular back in the day (~2000), but had thought it's popularity had waned
much more than it apparently has. I last deployed systems with rl in them
around 2007, and at the time it was trailing edge gear (the SBCs we used at
Timing Solutions tended to use popular, but ~5-year-old technology because
that market segment wanted longevity of spare availability...).

>>> Please direct replies to freebsd-arch <<<
A few points of clarification:
Rod correctly points out that this message makes it look like the FCP is
a done deal as written. This is not the case and we welcome feedback
on the entire proposal. IMO, soliciting input on the list of drivers
along with the proposed process is a way to keep discussion concrete so
we will proceed with both.
It was asked: when does iflib conversion need to occur to save a driver?
My proposed plan it to proceed with deprecation notices of otherwise
unpopular drivers, but conversion can come in and remove those notices
at and upto (or even after) removal from the tree.
In an effort to save some email, we will be moving rl(4) to the list of
drivers to STAY as it has proved itself to be popular. A few others
appear to be well on their way so keep the reports coming.
Thanks,
Brooks
P.S. As a person who has edited every driver in the tree multiple times
in the last year (mostly in an external tree), I will consider this
process successful even if we keep the majority of listed drivers in the
tree.

It's definitly on the STAY list at this point. If you could help get it
update that would be great, especially if it's still shipping (a very
useful datapoint).

OK. I'd have thought those SBCs would have gone out of production years
ago.... It's a good datapoint to know that there's multiple users of
FreeBSD using these parts in products that are still shipping. That's a
clear and compelling benefit to the project that offsets the efforts that
it's taken them to keep things current with rl.
In this case, though, rl is off the list, so that hardware should still be
good. The only other SBC I was aware of at Timing Solutions was one that
had an 'ed' chip on it (an ISA realtek part IIRC) that was used in around
2001, but in a 'one off' custom setup that I don't think will ever be
upgraded.... But I have to ask since I know how things worked during my
time there and systems that 'would never be upgraded' often times were
later...
I'd also suggest that rl stands in stark contrast to the cs, wb, sn, smc,
sf, tl, tx and vr drivers, which nobody has mentioned in this thread, and
which I doubt are in use in any FreeBSD system of any age today.

11 years later, we (Timing Solutions, now a division of Microchip) are
still using SBCs with rl(4) hardware and still shipping software
updates with that driver built into the kernel. We build systems with a
lifespan in the field of 20 years or more, and the stability and
compatibility across OS upgrades over that kind of span is a BIG reason
to use freebsd rather than linux for such things.

I'll assume that you've deployed more than 5 of these systems and that you
may someday upgrade them as well? Which of the Vortex86 processors are you
using, if you can answer that...

>FCP-01010 (https://github.com/freebsd/fcp/blob/master/fcp-0101.md)
Can I open a FCP to rename FCP to FBS (for FreeBSD BikeShed) ?
Guys... most if not all of these emails could have been sent to
directly Brooks without Cc'ing four mailing lists.
Then Brooks could revise his tallies and scores to match informed
reality and _then_ we could discuss if the criteria were sound
on the list(s).

I mentioned vx. Working fine here:

My firewall has most of them. It has 2 sk(4), 2 nfe(4), fxp(4), and
xl(4), with xl and fxp connected to my ISP and the others on my
internal network. My testbed has sk(4), nfe(4), and dc(4), connected to
my DMZ, for ipfilter testing. My main build machine and my current
laptop have sk(4), nfe(4), bge(4), while my i386 testbed (an old
laptop) has rl(4).
I have a spare motherboard (in case something breaks, while I purchase
a replacement) with nv(4). All parts, including CPUs, are
interchangeable.

As various others have stated, this isn't true. All the code in FreeBSD has
an ongoing maintenance cost and is an impediment to adding new features.
There is no point in spending valuable developer effort to update drivers
and test them with unusual/obsolete hardware unless those drivers are going
to actually be used.

That language is uncalled for.

Supporting NICs that no-one uses doesn't benefit anyone. No-one is talking
about removing NICs that are in active use.

Those netbooks are more than a decade old now and I don't expect many are
still functional. Will people still expect to use them with FreeBSD 13 in 5
years time?

What is the purpose in keeping unused FastEthernet cards in the tree?

Again, that language is uncalled for.

Hello,
freebsd 11.2/amd64 release
net-snmp-5.7.3_18
net-snmpd returns incomplete MAC addresses in IF-MIB::ifPhysAddress,
the first octet is always "0".
$ snmpwalk -v 2c -c "xxx" localhost 1.3.6.1.2.1.2.2.1.6
IF-MIB::ifPhysAddress.1 = STRING: 0:36:9f:93:7d:f8
IF-MIB::ifPhysAddress.2 = STRING: 0:36:9f:93:7d:fa
IF-MIB::ifPhysAddress.3 = STRING: 0:f4:bb:ef:c8:e4
...
$ ifconfig | grep ether
ether a0:36:9f:93:7d:f8
ether a0:36:9f:93:7d:fa
ether ec:f4:bb:ef:c8:e4
tcpdump confirms that the problem is in net-snmpd (and not the client).
Also when using the MIB IP-MIB::ipNetToMediaPhysAddress the MAC
addresses are correct.
$ snmpwalk -v2c -c '***r***' localhost IP-MIB::ipNetToMediaPhysAddress | grep a0:36:9f:93:7d:f8
IP-MIB::ipNetToMediaPhysAddress.13.10.10.1.118 = STRING: a0:36:9f:93:7d:f8
I've checked net-snmpd 5.7.3 under linux and the mac addresses are
correct. (So it's specific to FreeBSD.)
Any clue ?
Thanks, regards.

It looks like net-snmp being stupid, try the attached patch (put to files/).

We have bsnmpd in the base system. Does it exhibit same problem?

I have many hosts using ed & rl, several using ep, & at least one
using xe or ex. That's just from memory, maybe other drivers in peril.
Unless the functionality of drivers is sub-sumed in to other drivers,
stripping all those drivers would motivate some to never upgrade
again, or dump FreeBSD for a more conservative BSD, or fork FreeBSD etc.
Stripping dead code helps developers play easier, but stripping
live code is offensive. Some who periodicaly propose code demolitions
forget that many users of FreeBSD don't subscribe lists, except
maybe announce, as too busy, maintaining FreeBSD on networks ...
until their nets don't work.
Cheers,
Julian

Later in the thread rl was removed from the list.
What systems are you running ed, ex and/or xe on? So far I've heard no
reports of people using the latter two in about a decade.

You could also create a port/pkg for them and assume the burden of
maintenance yourself.

I think in this case there will be plenty of warning. They will upgrade to
12, one assumes, and see the deprecation message in their new kernel logs.
There's going to be about a 6 month window between when this is announced
and when it happens to collect evidence that removal is unwarranted, to
show they are still in use by enough people to justify their on-going (yes
non-zero) cost to keep in the tree. There's over 2 years before they will
be removed from a released version: also plenty of time to build a case
that they are in use and/or upgrade to different, supported NICs. If you
look at the rest of the thread, you'll see several people have made
compelling cases and/or provided evidence of continued use into the future
to keep the drivers in the tree. Evidence will save them, but harsh words
will not.
I think expecting people to blindly maintain code on the off chance someone
is still using is offensive as well. We must weigh the costs of continuing
with the benefits those cost provide. We don't have good sources of data
for what's still in use and what's not, so we have to rely on these
periodic calls for data to ensure we aren't wasting our time on hardware
that's no longer used.

I have a card that is 10/100 only, but works fine with the gigabit alc driver:
alc0: <Atheros AR8162 PCIe Fast Ethernet> port 0x2000-0x207f mem 0xe0500000-0xe053ffff irq 16 at device 0.0 on pci1
cheers, jamie

Do we currently support those simulators? I see it is in the VERSATILEPB

Yes, I boot FreeBSD/arm64 on them in a local Jenkins instance.

A commit references this bug:
Author: shurd

New revision: 339207
URL: https://svnweb.freebsd.org/changeset/base/339207
Log:
Fix igb corrupting checksums with BPF and VLAN
When using a vlan with igb and the vlanhwcsum option, any mbufs which
already had the TCP, UDP, or SCTP checksum calculated and therefore don't
have the CSUM_[IP|IP6]_[TCP|UDP|SCTP] bits set in the csum_flags field wo=
uld
have the L4 checksum corrupted by the hardware.
This was caused by the driver setting E1000_TXD_POPTS_TXSM any time a
checksum bit was set OR a vlan tag was present.
The patched driver only sets E1000_TXD_POPTS_TXSM when an offload is
requested.

That's a partial relief.

I can look more later, but for a quick partial reply:
I keep an incomplete ad hoc occasionaly/rarely updated list of logs,
useful for odd questions such as this, so I can run quick checks
cd ~/tech/log/dmesg ; grep ed0: * */* | grep port # ... vi
dual film flip lapn loft slim wind
cd ~/tech/log/ifconfig ; grep ed0: * */*
dual film flip lapl loft park rain snow wall wind
cd ~/tech/log/dmesg ; grep xe0: * */*
lapd lapo
cd ~/tech/log/ifconfig ; grep xe0: * */*
nothing
cd ~/tech/log/dmesg ; grep ex0: * */*
nothing
cd ~/tech/log/ifconfig ; grep ex0: * */*
nothing
Hosts above are custom PCs no model numbers, but these are standard laptops:
xe: lapd: Digital HiNote Ultra2000 http://www.berklix.com/~jhs/hardware/digital/
ed: lapl: Toshiba Libretto 70CT http://www.berklix.com/~jhs/hardware/toshiba/libretto/
ed: lapn: Dell Latitude XPi P133ST http://berklix.com/~jhs/hardware/laptops/dell_latitude_xpi_p133st
xe: lapo: Novatech (MiTAC) 8355 http://www.berklix.com/~jhs/hardware/laptops/novatech-8355/
( PS ed0 is also used by Hewlett Packard Network ScanJet 5 a multi sheet
feeder with FreeBSD built inside, however that's stuck on a seriously
old release, still a great device though - http://berklix.com/scanjet/ )
PS My master kernel config from pre 4.11 to current:
http://www.berklix.com/~jhs/src/bsd/fixes/FreeBSD/src/jhs/sys/amd64/conf/HOLZ
So quick summary:
ex: I dont seem to use
ed: I use on many of my hosts, not just those above, & I have some spare
to stick in to any PCI or ISA box I work on if needed.
ed & xe I also have on pcmcia & cardbus, so they move around between laptops.

Didn't know drivers could be farmed out to ports/, sounds like a

Yes, needs careful balance.

Yep, sorry I wasn't clear. That's what I meant - I was responding to someone
who was worried that the support was being dropped for 100Mbps cards.
