   There shouldn't be any input errors - this is indicating that something is
wrong. The version of the driver in 2.1.6 doesn't support full duplex, but
the card will try to negotiate it in any case. If you have the machine
connected to a switch, then this is likely the problem. You'll need to
configure the switch port to half duplex or upgrade to the current release
of FreeBSD (which supports full duplex operation).
