net/sched: cls_flower: Support matching on SCTP ports
Support matching on SCTP ports in the same way that matching
on TCP and UDP ports is already supported.
Example usage:
tc qdisc add dev eth0 ingress
tc filter add dev eth0 protocol ip parent ffff: \
flower indev eth0 ip_proto sctp dst_port 80 \
action drop
