sky2, tx timeout

[Martin Korous <korous@thinline.cz>]

Hello,

I want report a bug in sky2 driver. Sky2 will shutdown every 5-6 days.
Result is reboot or "rmmod sky2 && modprobe sky2"
I have changed eth0 for eth1 (sky2 is on intranet now) because there is 
smaller traffic, but
sky2 will shutdown again in 5-6 days.
follow some info from logs and about network card

NOTICE: I dont have subscribe LKML, if you want more info from me, 
answer to my e-mail.

regards
Martin Korous
