Hi,
I get some strange networking results with my RealTek 8139 card. I
don't know how long these problems exist in the kernel, because they
only showed up after some change in my network setup.
I got a third PC for testing and now needed a hub to connect all my
PCs together. I used to have an UTP x-over cable and this setup worked
Ok. Now I hooked the 3 PCs together with an 10/100 MBit Hub.
This is now my configuration:
PC 1: RealTek 8139
PC 2: Intel EtherEpress Pro 100B
PC 3: RealTek 8029 (the new machine)
PC 1 and PC 3 are running FreeBSD, PC 2 usually runs Windows 98, but
I could also boot Solaris for testing.
Under normal Circumstances, the communication is Ok between all three
machines, but sometimes the ethernet interface in the main machine
(the 8139) wedges up. I cannot ping any other host. The only solution
is taking the interface down and up again:
ifconfig rl0 down; ifconfig rl0 up
Enabling/disabling promiscuous mode also seems to help.
I first thought it was a faulty hub, so I hooked up two PCs (RealTek
8139 + RealTek 8029) with the Xover cable again. But the problem
persists. So the Hub seems to be Ok.
There seem also to be plenty of mbufs available. netstat -m:
64/3808 mbufs in use:
56 mbufs allocated to data
8 mbufs allocated to packet headers
1/48/512 mbuf clusters in use (current/peak/max)
572 Kbytes allocated to network (1% in use)
0 requests for memory denied
0 requests for memory delayed
0 calls to protocol drain routines
I finally managed to easily reproduce the behaviour. Just run two
flood pings to the same machine at once.
Interesting, that I have to flood ping PC 3 (10BaseT) to wedge up
the machine. If I ping PC 2, nothing spectacular happens.
The Driver does proper autonegotiation, but also changing the media
manually to the correct values (media 100baseTX mediaopt half-duplex)
doesn't help.
Thanks for any hints.
Daniel
Some comments to the dmesg output below:
I have disabled the secondary serial port, so every device should
get its own IRQ.
