[dpdk-dev] [PATCH 08/15] igb: Convert to use of PMD_REGISTER_DRIVER and fix linking

[Neil Horman <nhorman@tuxdriver.com>]

convert the igb pmd driver to use the PMD_REGISTER_DRIVER macro.
This means that the test applications now have no reference to the igb 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.
