From 0ad5daf6ba80af4a8d72b4284079357c4e3b9e4a Mon Sep 17 00:00:00 2001 From: Vivien Didelot Date: Mon, 1 May 2017 14:05:23 -0400 Subject: 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. Signed-off-by: Vivien Didelot Reviewed-by: Andrew Lunn Signed-off-by: David S.
