This is a tested version of the virtio Tx performance improvements
that I posted earlier on the list, and described at the DPDK Userspace
meeting in Dublin. Together they get a 25% performance improvement for
both small packet and large multi-segment packet case when testing
from DPDK guest application to Linux KVM host.

Stephen Hemminger (5):
  virtio: clean up space checks on xmit
  virtio: don't use unlikely for normal tx stuff
  virtio: use indirect ring elements
  virtio: use any layout on transmit
  virtio: optimize transmit enqueue
