* Robin Woolard <RWoolard@NewWorldApps.com> [20010613 17:28]: writing on th=
e subject 'dual port nic support?'
Robin> What options do I need to use to compile my kernel with dual port nic
Robin> support? I have an Intel ISP1100 server with a single onboard Intel=
Pro
Robin> +Server 10/100 Ethernet adapter. The nic is an 82559 and has two RJ=
-45
Robin> ports that both use the 82558 chip. The results of a "dmesg |grep f=
xp" are
Robin> as follows:
Haven't used such a card though......
Robin>=20
Robin> fxp0: <Intel Pro 10/100B/100+ Ethernet> port 0xef00-0xef3f mem
Robin> 0xff900000-0xff9fffff,0xffafe000-0xffafefff irq 5 at device 12.0 on =
pci0
Robin> fxp0: Ethernet address 00:d0:b7:56:0b:98
Robin> fxp1: <Intel Pro 10/100B/100+ Ethernet> port 0xee80-0xeebf mem
Robin> 0xff700000-0xff7fffff,0xffafd000-0xffafdfff irq 5 at device 13.0 on =
pci0
Robin> fxp1: Ethernet address 00:d0:b7:56:0b:99
This shows that both interfaces are CORRECTLY detected
Robin> fxp0: promiscuous mode enabled
Robin> fxp0: promiscuous mode disabled
I don't know why you're running on this mode....tcpdump???
Robin> So, basically, right now the two share an IRQ. I'm not exactly sure=
if they
Robin> should or not. =20
I don't see any conflicts, so I guess it is okay for PCI devices to share
IRQ, yes?
Robin> The first interface, fxp0, is fine. It works as it should. When I =
bring up
Robin> fxp1, however, I can only see broadcast traffic and nothing else eve=
n when
Robin> in promiscious mode. When compiling the kernel, should the copy of
Robin> /usr/src/sys/i386/conf/GENERIC file be configured like this?:
Robin>=20
Robin> device fxp0 at isa? port 0xef00-0xef3f irq 5
Robin> device fxp1 at isa? port 0xee80-0xeebf irq {insert unused=
irq
Robin> here}
I think you _only_ need a single line;
device fxp
Robin> Just in case you were wondering, my rc.conf file is configured like =
this:
Robin>=20
Robin> network_interfaces=3D"fxp0 fxp1"
Robin> ifconfig_fxp0=3D"inet 172.16.83.231 netmask 255.255.255.0"
I guess you should have;
network_interfaces=3D"auto"
ifconfig_fxp0=3D"inet w.x.y.z netmask 255.255.255.0"
ifconfig_fxp1=3D"inet a.b.c.d netmask 255.255.255.0"
defaultrouter=3D"212.22.163.1"
But since the cards are on the same -net, I guess there are some issues
about it....others may be able to tell you more ;)
