dc1: watchdog timeout

[<ninjaz_(_at_)_webexpress_(_dot_)_com>]

I've having trouble with a D-Link DFE-570TX 4 port ethernet card.  The
first port works fine using either the dc or de driver, but the second
port will not carry traffic.

I first tried this with OpenBSD 3.0-stable (from a month or so ago), then
upgraded from 3.1 release branch today.

On 3.0-stable I had been using the de driver, as that's what won in
detection.  The ethernet carrier signal was detected, but pings to a
machine on its subnet were failing.  Eventually with "ping: sendto: No
buffer space available"

That led me to compile a new kernel commenting out the de driver to give
dc a try.  This time, instead of the sendto: No buffer space available
error, the "dc1: watchdog timeout" errors appear.

The same behavior persists in 3.1.   I've tried switching to a new cable,
as suggested in dc(4) with no change in behavior.

I've noticed that Oerrs increment in the output of netstat -I dc1 whenever
I try to ping over that interface:

Name    Mtu   Network     Address              Ipkts Ierrs    Opkts Oerrs

Any suggestions?
