Subject: [PATCH net-next 0/6] Egress VLAN modification using VCAP ES0 on Ocelot switches

This patch set adds support for modifying a VLAN ID at the egress stage
of Ocelot/Felix switch ports. It is useful for replicating a packet on
multiple ports, and each egress port sends it using a different VLAN ID.

Tested by rewriting the VLAN ID of both
(a) packets injected from the CPU port
(b) packets received from an external station on a front-facing port

Adding a selftest to make sure it doesn't bit-rot, and if it does, that
it can be traced back easily.

Vladimir Oltean (6):
  net: mscc: ocelot: support egress VLAN rewriting via VCAP ES0
  net: mscc: ocelot: write full VLAN TCI in the injection header
  net: dsa: tag_ocelot: set the classified VLAN during xmit
  selftests: net: mscc: ocelot: bring up the ports automatically
  selftests: net: mscc: ocelot: rename the VLAN modification test to
    ingress
  selftests: net: mscc: ocelot: add a test for egress VLAN modification
