I was incorrect about the Tx/Rx queues for ixgbe:
-igb-
82575 - 4 Tx/Rx, 4 RSS
82576 - 16 Tx/Rx, 16 RSS
82580 - 8 Tx/Rx, 8 RSS
i350 - 8 Tx/Rx, 8 RSS
i210 - 4 Tx/Rx, 4 RSS
i211 - 2 Tx/Rx, 2 RSS
-ixgbe-
82598 - 64 Rx/32 Tx, 16 RSS
82599 - 128 Rx/Tx, 16 RSS
X540 - 128 Rx/Tx, 16 RSS
Hope this helps,
Jeff
