   The patch was applied as a separate patch.

 - Rebase on "remove pci driver from vdevs".
 - Optimize RX/TX functions.
 - Fix resource leaks.
 - Fix compile issue.
 - Add patch to fix vhost library.

RFC PATCH v3 changes:
 - Optimize performance.
   In RX/TX functions, change code to access only per core data.
 - Add below API to allow user to use vhost library APIs for a port managed
   by vhost PMD. There are a few limitations. See "rte_eth_vhost.h".
    - rte_eth_vhost_portid2vdev()
   To support this functionality, vhost library is also changed.
   Anyway, if users doesn't use vhost PMD, can fully use vhost library APIs.
 - Add code to support vhost multiple queues.
   Actually, multiple queues functionality is not enabled so far.

RFC PATCH v2 changes:
 - Fix issues reported by checkpatch.pl
   (Thanks to Stephen Hemminger)
