Hi all,

I have updated sk(4), major parts are obtained from OpenBSD:
1) interrupt moderation time is decreased, it boost netperf's
UDP/TCP_RR performance(increase ~20%) and shows no degradation in
TCP/UDP_STREAM performance
2) recognize more cards
3) include a fix for "watchdog timeout"
Many thanks. Should I go to your country, I'll take you a bottle of 
wine. :-)

Please test/review it:

It is against HEAD

Erm, is it against latest HEAD (the reorganized source tree)?
