Subject: [PATCH net-next v2 14/18] net: dsa: mv88e6xxx: add VTU Load/Purge operation
Add a new vtu_loadpurge operation to the chip info structure to differ
the various implementations of the VTU accesses.
Now that the STU handling is abstracted behind VTU operations, kill the
obsolete MV88E6XXX_FLAG_STU flag.
