Hmm, I'm afraid it's difficult to debug it only by code inspection,
but could you check which TX or RX could cause problem (by ttcp etc.)
and interrupt/network statistics during stall (by vmstat -i or
netstat -i etc.)?

If FreeBSD or OpenBSD have the similar problem, maybe
we need chip docs (there are several magic in the source).
