VCAP IS1 is a VCAP module which can filter MAC, IP, VLAN, protocol, and
TCP/UDP ports keys, and do Qos classified and VLAN retag actions.
This patch added VCAP IS1 support in ocelot ace driver, which can supports
vlan modify and skbedit priority action of tc filter.
Usage:
tc qdisc add dev swp0 ingress
tc filter add dev swp0 protocol 802.1Q parent : flower \
skip_sw vlan_id 1 vlan_prio 1 action vlan modify id 2 priority 2
