amd64/73360: sk0: watchdog timeout

[Bjoern A. Zeeb]

> I have an AMD64 machine with an ASUS motherboard and an on-board syskonect gigabit ethernet. The syskonect is periodically going mute. It still receives packets but will not transmit. This happens in both gigabit and 100BaseT modes.

how do you know that it still receives packets ?

- can you see counters increasing ?
- can you see packets coming in using tcpdump or such ?
