Ueaah ! I confused !
We haven't any serious transmit errors, because I
didn't seen any error message like xl0: watchdog timeout.
After analyzing if_xl.c I understood source of this big Oerrs
count: as output errors driver treated xl_stats.tx_deffered, I
guess number of deffered transmitted frames. After manually
ifconfig'uring xl0 interface with media/mediaopt or after
pacthing I seen performance impact on this NIC 650Kb/s with
NE2000 as peer. Also I'm not feel delays due to recieve errors,
but before telnet from 3c905 box looks like busy
ppp connection :-( .
One suspicuous thing: I tried to test this NIC in times of
our network inactivity but we has big number of collisions:
250, 332, 400 ! It's not good !
