[PATCH v1 net-next 4/6] net: mscc: ocelot: VCAP IS1 support

From: Xiaoliang Yang
Date: Wed May 06 2020 - 03:54:09 EST

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