The patch adds the test framework for OVS using afxdp. Currently there are two test cases, using ping and http as traffic forwarding through ovs with 2 afxdp netdev. Signed-off-by: William Tu <u901206

The patch creates a new netdev type "afxdp" and copies some of the afxdp api implementation from xdpsock_user.c at linux sample code. The afxdp ebpf programs/maps are loaded when dpif-netdev is create

AF_XDP requires attaching an xdp program and xskmap for each netdev. The patch provides these program/map and the loading and attaching implementation. Signed-off-by: William Tu <u9012063@...> --- aci
