tc: flower: Allow *_mac options to accept a mask
* The argument to src_mac and dst_mac may now take an optional mask
to limit the scope of matching.
* This address is is documented as a LLADDR in keeping with ip-link(8).
* The formats accepted match those already output when dumping flower
filters from the kernel.
Example of use of LLADDR with and without a mask:
tc qdisc add dev eth0 ingress
tc filter add dev eth0 protocol ip parent ffff: flower indev eth0 \
src_mac 52:54:01:00:00:00/ff:ff:00:00:00:01 action drop
tc filter add dev eth0 protocol ip parent ffff: flower indev eth0 \
src_mac 52:54:00:00:00:00/23 action drop
tc filter add dev eth0 protocol ip parent ffff: flower indev eth0 \
src_mac 52:54:00:00:00:00 action drop
