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 v2
- Support mirroring egress and ingress traffic to different ports
- Check for invalid configurations when multiple ports are mirrored
