[dpdk-dev] [RFC PATCH 2/7] lib/librte_vhost: Add an abstraction layer for vhost backends

[Tetsuya Mukawa <mukawa@igel.co.jp>]

The patch adds an abstraction layer for vhost backends.
So far CUSE is the only one vhost backend. But QEMU-2.1 can have one
more backend called vhost-user. To handle both backends, this kind of
layer is needed.

Signed-off-by: Tetsuya Mukawa <mukawa@igel.co.jp>
