The problem was that the driver code was not properly obtaining
error statistics from the Broadcom chip, thus errors _were_
(before the fix) not being calculated/accounted for.  Now (after
the fix) errors are being accounted for correctly.

So the errors you see in your netstat output are probably real/
ccurate.  I'll vote for a duplex-related problem or some naughty
cabling.
