I have this repeatable behavior of Ethernet driver when it has an
error:

This repeats on each attempt to send packets. That is OK, but bad
thing is it does not recover when cabling gets fixed. Removing/loading
3c59x module fixes that, but this is very sad solution, since it breaks
existing users' sessions. Can this be fixed somehow?
My setup: 2.0.30 kernel, this is what module prints on load:
3c900.c:v0.40 4/16/97 becker@cesdis.gsfc.nasa.gov
loading device 'eth0'...
eth0: 3Com 3c905 Boomerang 100baseTx at 0xef00, 00:60:97:5b:3f:ac, IRQ 9
8K word-wide RAM 3:5 Rx:Tx split, autoselect/MII interface.
Rx Pacing bug exists, disabling bus-master receives.
Card runs on 10Mbit, if this makes any difference.
