[dpdk-dev] [PATCH 05/19] ring: convert the ring pmd driver to use the PMD_INIT_NONPCI macro

[Neil Horman <nhorman@tuxdriver.com>]

Separate the ring pmd from calls within the core eal library so that it will
not be loaded unless needed (or compiled in statically)

Note: The demo test application calls directly into the ring pmd driver, and
that needs to be cleaned up, so that the -d option is used on the command line
to test the proper pmd.  for now I've just added linkage to the pmd directly to
avoid build breaks and will fix up the application operation in a subsequent
patch
