I see the problem... ex_getstats() counts deferrals as oerrors, which
is incorrect. Deferrals are a normal part of Ethernet transmissions,
and should only be counted as errors if an excessive number of them
occurs (which causes the packet transmission to fail).
The bug in the driver is harmless; it just skews the stats.
