Subject: xdp: T2666: initial XDP (generic mode) forwarding support

The CLI command 'set interfaces ethernet <interface> offload-options xdp" enables
the XDP generic mode on the given interface.

vyos@vyos:~$ show interfaces ethernet eth1
eth1: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 xdpgeneric/id:151 qdisc mq state DOWN group default qlen 1000
    link/ether 00:50:56:bf:ef:aa brd ff:ff:ff:ff:ff:ff
    inet6 fe80::250:56ff:febf:efaa/64 scope link tentative
       valid_lft forever preferred_lft forever
    Description: fooa

XDP code is thankfully copied from [1], thank you for this nice tutorial.

NOTE: this is an experimental feature which might break your
forwarding/filtering.
