82598, 82599, X520, and X540 can have up to 64 Tx/Rx queues (1 per CPU), bu= t are limited to 16 RSS queues.=20 For igb it varies, depending on HW. I can put together a list.

The oldest hardware supported by the ixgbe driver is the 82598, which supports up to 16 RSS queues (see Table 3-48 in the 82598 datasheet). I believe that the 82599 and X520 are more capable. I have no idea what the situation is on igb, as there seems to be a lot more hardware supported by that driver and I don't work with the 1GB devices very much. _______________________________________________ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscribe@freebsd.org"
