re(4) and Realtek 8168

[Dima Veselov <kab00m%lich.phys.spbu.ru@localhost>]

Hello,

I found a problem with Realtek 8168 chips and NetBSD-5.*. I've tried 
NetBSD-5/i386, NetBSD-5.99.7, 11 and 15 i386 and amd64 snapshots with same 
result.

Card is working several minutes, it may even take dhcp address. After little 
work it stops responding and I get constant messages:
Jul 15 22:30:21 allegro /netbsd: re0: watchdog timeout
Jul 15 22:30:21 allegro /netbsd: re0: reset never completed!

Searching google i found several messages with same troubles, concerning 8111 
and NetBSD 4.x.

Does anyone know what is a problem and what can I do to help fix it?
