net: Add IFLA_XDP_PROG_ID
Expose prog_id through IFLA_XDP_PROG_ID. This patch
makes modification to generic_xdp. The later patches will
modify other xdp-supported drivers.
prog_id is added to struct net_dev_xdp.
iproute2 patch will be followed. Here is how the 'ip link'
will look like:
> ip link show eth0
3: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 xdp(prog_id:1) qdisc fq_codel state UP mode DEFAULT group default qlen 1000
