Nevim, jestli ty chyby souviseji s tou propustnosti nebo se jedna o jiny 
problem.

Nasel jsem v sysctl nasledujici, ale z toho ja osobne opravdu asi nic 
zvlastniho nevyctu...
jo, jeste jsem na em0 podle rady Petra Macka zkusil vypnout TSO a pro 
jistotu i VLAN_HWTSO, tak uvidim, jestli neni zakopany pes nahodou i zde.
