3C905, many RX error and poor performance.

[David Putney]

I actually have also been seeing a problem with receiving packets, but have not
had enough time to investigate the problem.  It seems that I get a large number
of overruns while running some scripts.  These scripts run multicast flows
between various machines, then copy files using rcp afterwards.  In particular,
the cards that seem affected are specifically the 3c905Bs.
I'll have to try the diagnostics soon...
