Hello, Network Performance Gurus! I have Debian Jessie with 3.16 kernel, DPDK 2.0.0 with ixgbe NIC. And I wrote following code: https://gist.github.com/pavel-odintsov/e1f64de4d56c0ab1b37c
I try to allocate 2 queues for TX and only 1 queue for RX and I can't do it with error (detailed error message https://gist.github.com/pavel-odintsov/507cf7a082793f547120): PMD: ixgbe_dev_rx_queue_setup(): sw_ring=0x7f9e9dcdbc80 hw_ring=0x7f9e9dd41500 dma_addr=0x36b41500 PMD: ixgbe_dev_tx_queue_setup(): sw_ring=0x7f9e9dcd9b40 hw_ring=0x7f9e9dd51580 dma_addr=0x36b51580 PMD: ixgbe_set_tx_function(): Using simple tx code path PMD: ixgbe_set_tx_function(): Vector tx enabled. EAL: Error - exiting with code: 1 Cause: Can't configure TX queue 1 for port 0 I could fix this issue with allocation 2 queues for TX and 2 queues for RX. But it's useless for my aplication because I need multiple TX queue but could use only one RX and I want ability to specify different number of queues for NIC. Thank you so much! -- Sincerely yours, Pavel Odintsov
