Title:
  virtio only support packed ring size power of 2

Status in QEMU:
  Expired

Bug description:
  Issue discription:
  When QEMU starts with "-device 
virtio-net-pci,netdev=netdev0,mac=52:54:00:00:00:01,disable-modern=false,mrg_rxbuf=on,rx_queue_size=1025,tx_queue_size=1025,mq=on,vectors=15,packed=on"

  It raises error: Invalid rx_queue_size (= 1025), must be a power of 2
  between 256 and 1024

  Analysis:
  According to virtio1.1 spec, the packed queue size value does not have to be 
a power of 2.
