A simple bridge between the two interfaces acts as expected with packets being distributed fairly evenly across all of the rx/tx queues. We then switched to tagged vlans on both interfaces (10 vlans each, 8 source and 8 dest addresses per vlan) and bridged eth0.N to eth1.N, and many of our queues (and CPUs) remained idle, and all of our VLAN traffic went out on the same tx queue. Are multiple transmit queues supported with 802.1q? How do we figure out what is causing some of our receive queues to be unused? We are using 2.6.31 (from Debian) and ixgbe-2.0.44.14 . eth0: tx_queue_0_packets: 0 tx_queue_1_packets: 0 tx_queue_2_packets: 138 tx_queue_3_packets: 123960995 tx_queue_4_packets: 0 tx_queue_5_packets: 0 tx_queue_6_packets: 36 tx_queue_7_packets: 36833 rx_queue_0_packets: 24841529 rx_queue_1_packets: 24832268 rx_queue_2_packets: 0 rx_queue_3_packets: 24835876 rx_queue_4_packets: 0 rx_queue_5_packets: 24833101 rx_queue_6_packets: 0 rx_queue_7_packets: 24833463 eth1: tx_queue_0_packets: 0 tx_queue_1_packets: 0 tx_queue_2_packets: 138 tx_queue_3_packets: 124174228 tx_queue_4_packets: 0 tx_queue_5_packets: 0 tx_queue_6_packets: 82 tx_queue_7_packets: 78 rx_queue_0_packets: 24832675 rx_queue_1_packets: 24789655 rx_queue_2_packets: 0 rx_queue_3_packets: 24793220 rx_queue_4_packets: 0 rx_queue_5_packets: 24797484 rx_queue_6_packets: 0 rx_queue_7_packets: 24786851 -- Eldon Koyle -- BOFH excuse #46: waste water tank overflowed onto computer
