This patch support multiple queues feature in DPDK based virtio-net frontend.
It firstly gets max queue number of virtio-net from virtio pci configuration
and then send command to negotiate the queue numer with backend;
when receiving and transmiting packets, negotiated multiple virtio-net queues
An automated unit test for the new API to allow a ring to be used as an
ethdev. Verifies that expected enqueue/dequeue functionality still
works.

Add in a pair of functions which meet the criteria for rx_burst and
tx_burst, which then allow a ring to be used as though it were an
ethdev, so that code can be written agnostically. Provide a convertion
function that takes a single ring and returns an index of the ethdev
corresponding to it.

This allows us to get the ethdev structure definition without a full
set of additional headers from other libs being included.
To ensure compilation, add new includes to C files that needed mbuf
header without explicitly including it.

This patch set aims to provide a shorter simpler alternative the public API
functions for using rings as ethdevs provided by the librte_pmd_ring library.
This alternative just provides simple RX and TX burst functions and a
conversion API, without any of the complexities present in the pmd_ring

Problems with lib rte_malloc:
1. Rte_malloc searches a heap's entire free list looking for

2. Heaps store free blocks in a singly-linked list, resulting

adjacent block.
