From ef0a731882a2bf120511072a08d973f65d00d979 Mon Sep 17 00:00:00 2001 From: Andrew Lunn Date: Sat, 3 Dec 2016 04:35:16 +0100 Subject: [PATCH] net: dsa: mv88e6xxx: Implement mv88e6390 tag remap The mv88e6390 does not have the two registers to set the frame priority map. Instead it has an indirection registers for setting a number of different priority maps. Refactor the old code into an function, implement the mv88e6390 version, and use an op to call the right one.
