    About VF multiple queue

    wtao000

      I have a Dual-port Intel 82599 NIC.

       

      My testbed is Ubuntu 14.04, ixgbe driver 5.2.3, ixgbevf 4.2.1.

       

      I initialize one VF by executing

       

      echo 1 >> /sys/bus/pci/devices/0000\:06\:00.0/sriov_numvfs

       

      However, the number of queue pair attached to this VF is only 1, as shown in the dmesg

       

      [  727.882194] ixgbevf 0000:06:10.0: Multiqueue Disabled: Rx Queue count = 1, Tx Queue count = 1

       

      This is may be not consistent with the Intel 82599 data sheet, which shows a pool of queue pairs (e.g., 8, 4 or 2) is assigned to the VF interface.

       

      My question is how to configure VF multiple queue correctly?
