OK, we'll try. Is there any problems with any of supported chipsets in
em-driver with polling? There many negative answer about polling support in
fxp on 82550, and good answers about 82558 and 82559 with fxp-driver.

Intel SCB2, integrated NIC on PCI 33Mhz bus. We use only one NIC, with five
802.1q vlan sub-interfaces configured. Is there any ideas how can I diagnose
bottlenecks on bus?
With best regards, Oleg Gawriloff.
