I think that Intel 82575 (and another models) hardware are capable of multiple queues both on the receive and the send side. Is it right? Currently the processing of packets is limited to one CPU per NIC. Can we have multiple taskq processes for one NIC in parallel? Is anyone working on this right now, and if not does this sound like something anyone is interested in doing? (yes, I know the Yandex driver). -- Best regards, Rafael
