Subject: [PATCH net-next 3/6] net: dsa: mv88e6xxx: add support for 6390 ATU Move
The 6390 family of Marvell chips uses 5 bits to describe the ToPort and
FromPort values of PortVec in the ATU Move operation, while older
switches use 0xf.
Add an atu_move_port_mask member in the info structure to describe that.
