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.
