That doesn't look so nice to me... 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 !
