net: dsa: mv88e6xxx: Add support for port mirroring
This patch series 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

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
