linux-gen: pktio: add AF_XDP socket based packet IO
Add new AF_XDP socket based packet IO implementation. Information about
AF_XDP and XDP can be found in [1].
ODP packet pool(s) created for packet IO entries are used as the UMEM
areas. Currently, only zero-copy mode is supported, copy-mode support
will be added later.
Depending on the XDP program loaded into the environment's NIC(s), TX
and RX queue selection for packets may differ. By default, only a single
combined queue is supported and this may require changing the
configuration of the NIC accordingly so that packets end up on the
AF_XDP socket created by ODP.
