Hi Vithal, The number of VF queues is decided by PF. Suppose you use kernel driver for PF. So the queue number is decided by PF kernel driver. I have a 82599ES, and find no matter ixgbevf or dpdk igb_uio is used, the rx queue number is 2. Frankly, I believe 2 is the expected number. Surprised that you get 8 when using ixgbevf. Hope this can help. Thanks.
