Instead of having a list of virtual device drivers in EAL code, add an API to register drivers. Thanks to this new registration method, we can remove the references to pmd_ring, pmd_pcap and pmd_xenvirt in EAL code. This also enables the ability to register a virtual device driver as a shared library. The registration is done in an init function flaged with __attribute__((constructor)). The new convention is to name this function rte_pmd_xyz_init(). The per-device init function is renamed rte_pmd_xyz_devinit(). By the way the internal PMDs are now also .so/standalone ready. Let's do it later on. It will be required to ease maintenance. Signed-off-by: Olivier Matz <olivier.matz@6wind.com> Acked-by: Thomas Monjalon <thomas.monjalon@6wind.com>
