Secondary process support had been disabled for the AF_XDP PMD because
there was no logic in place to share the AF_XDP socket file descriptors

APIs.
Rx and Tx are disabled in the secondary process due to memory mapping of
the AF_XDP rings being assigned by the kernel in the primary process only.
However other operations including retrieval of stats are permitted.
