This patchset refactors the DSA and mv88e6xxx code to use the switchdev FDB
objects.
The first two patches add minor but necessary changes to switchdev, the third
one implements the switchdev glue in DSA for FDB routines, and the remaining
ones refactor the FDB access functions in the mv88e6xxx co
The address in the switchdev_obj_fdb structure is currently represented
as a pointer. Replacing it for a 6-byte array allows switchdev to carry
addresses directly read from hardware registers, not stored by the

FID 0 means that multiple address databases are not being used).

chips we need to get the MAC address from the firmware.
Add a module parameter called 'mac_address' for this. It
will be used if no DT node can be found and the B2_MAC
register holds an invalid value.

The FMan MAC configuration code needs the speed and duplex information
for fixed-link interfaces that is parsed now by the of function
of_phy_register_fixed_link(). This parses the fixed-link parameters but
does not expose to the caller neither the phy_device pointer nor the
status struct where it
Use the speed and duplex information from the device tree fixed link
node accessing the status structure parsed by of_phy_parse_fixed_link().

Some drivers may need to parse the fixed link values before registering
the fixed link phy or access the status values. Separate the parsing from
the actual registration and provide an export for the added parsing function.
