Subject: [PATCH iproute2] iplink: document XDP subcommand to force the XDP mode.

When attaching an eBPF program to a device, ip link can force the XDP mode
by using the xdp{generic,drv,offload} keyword instead of just 'xdp'.
Document this behaviour also in the help output.

Signed-off-by: Matteo Croce <mcroce@...hat.com>
Fixes: 14683814 ("bpf: add xdpdrv for requesting XDP driver mode")
Fixes: 1b5e8094 ("bpf: allow requesting XDP HW offload")
