Ani ja ne. Priznam se, ze uz je moc tma. Popis co je co najdes v
http://sunsite.rediris.es/pub/mirror/intel/network/manuals/8254x_GBe_SDM.pdf
na strane 340 a dal.

Ale taky to muzes zkusit jinak - az se zase Ierrs o jednotku zvetsi, tak 
se podivej co se o jednotku zvetsilo tady. Jestli nic, tak to nebyla 4-8 
chyba, ale nektera z 1-3.

Mimochodem, Missed Packets/Receive No Buffers/RX overruns ukazuje, ze ti 
to obcas nestiha. I kdyz je pravda, ze v celkovem objemu pakety je to 
nepatrny zlomek. Mozna bys mohl trochu zvetsit hw.em.rxd

Vic me ale prekvapilo XON/XOFF Rcvd. To znamena, ze obcas nestiha to 
Cisco. Ale i tady je to zanedbatelny pocet pripadu.
