Subject: [PATCH 0/7] dsa: marvell: Add support for mv88e6071 and 6020 switches

This patch set provides following changes:

- Provide support for mv88e6020 and mv88e6071 switch circuits (the
  "Link Street" family of products including added earlier to this
  driver mv88e6250 and mv88e6220).

- Add the max_frame size variable to specify the buffer size for the
  maximal frame size

- The above change required adjusting all supported devices in the
  mv88e6xxx driver, as the current value assignment is depending
  on the set of provided callbacks for each switch circuit - i.e.
  until now the value was not explicitly specified.

- As the driver for Marvell's mv88e6xxx switches was rather complicated
  the intermediate function (removed by the end of this patch set)
  has been introduced. It was supposed to both validate the provided
  values deduced from the code and leave a trace of the exact
  methodology used.

  dsa: marvell: Define .set_max_frame_size() function for mv88e6250 SoC
    family
  dsa: marvell: Add helper function to validate the max_frame_size
    variable
  dsa: marvell: Correct value of max_frame_size variable after
    validation
  dsa: marvell: Modify get max MTU callback to use per switch provided
    value
