Hello!

This patchset is to provide high performance networking interface (virtio)
for container-based DPDK applications. The way of starting DPDK apps in
containers with ownership of NIC devices exclusively is beyond the scope.
The basic idea here is to present a new virtual device (named eth_cvio),
which can be discovered and initialized in container-based DPDK apps using
rte_eal_init(). To minimize the change, we reuse already-existing virtio
frontend driver code (driver/net/virtio/).

 With the aforementioned fixes i tried to run it inside libvirt-lxc. I got the following:
a) With hugepages - "abort with 256 hugepage files exceed the maximum of 8 for vhost-user" - i set -m 512
b) With --single-file - ovs runs, but doesn't get any packets at all. When i try to ping the container from within host side, it
counts drops on vhost-user port.

Kind regards,
