[dpdk-dev] [PATCH 0/X v5 12/14] virtio: Convert to use of PMD_REGISTER_DRIVER and fix linking

convert the virtio pmd driver to use the PMD_REGISTER_DRIVER macro.
This means that the test applications now have no reference to the virtio library
when building DSO's and must specify its use on the command line with the -d
option. Static linking will still initalize the driver automatically.
