Subject: [PATCH net-next v3 0/2] net: dsa: mv88e6xxx: Add support for port mirroring

This patch serie add support for port mirroring in the mv88e6xx switch driver.
The first patch changes the set_egress_port function to allow different egress
ports for egress and ingress traffic. The second patch adds the actual code for
port mirroring support.

Tested on a 88E6176 with:

tc qdisc add dev wan0 clsact
tc filter add dev wan0 ingress matchall skip_sw \
        action mirred egress mirror dev lan2
tc filter add dev wan0 egress matchall skip_sw \
        action mirred egress mirror dev lan3

Changes in v3

- Use enum for egress traffic direction
- Keep track of egress ports on mv88e6390
- Move booleans in struct for better structure packing

Changes in v2

- Support mirroring egress and ingress traffic to different ports
- Check for invalid configurations when multiple ports are mirrored
