Adds following tests:

1. AF_XDP SKB mode
    Generic mode XDP is driver independent, used when the driver does
    not have support for XDP. Works on any netdevice using sockets and
    generic XDP path. XDP hook from netif_receive_skb().
    a. nopoll - soft-irq processing
    b. poll - using poll() syscall

Could you have a patch to put xdpxceiver in .gitignore?

I see below:

   (use "git add <file>..." to include in what will be committed)

ACK, patch on the list now
