Merge branch 'dsa-next' 

Vivien Didelot says:

====================
net: dsa: push switchdev prepare phase in FDB ops

This patchset pushes the switchdev prepare phase for the FDB add and del
operations down to the DSA drivers. Currently only mv88e6xxx is affected.

Since the dump requires a bit of refactoring in the driver, it'll come in a
future patchset.

Changes in v2:
 * forward declare switchdev structs instead of fixing the dsa.h include.
