Hi,

I am using dpdk 1.5 where virtio pmd is available
in dpdk-1.5.1r2/lib/librte_pmd_virtio/.

When I run l2fwd reference application, I am getting the following error:

EAL: PCI device 0000:00:08.0 on NUMA socket -1
EAL:   probe driver: 1af4:1000 rte_virtio_pmd
EAL: PCI device 0000:00:09.0 on NUMA socket -1
EAL:   probe driver: 1af4:1000 rte_virtio_pmd
Lcore 0: RX port 0
Lcore 1: RX port 1
Initializing port 0...
EAL: Error - exiting with code: 1
  Cause: rte_eth_rx_queue_setup:err=-22, port=0

On debugging further, I see that in function virtio_dev_queue_setup, vq_size
is zero and hence returns error.

I was able to run e1000 pmd and virtio pmd *extension* successfully. Please
let me know if I need to set anything specifically to make virtio pmd to
work.

Thanks,
Selvaganapathy.C.
