From 240ea3ef70a4591ba0f77cfafe4b467d55ce80d0 Mon Sep 17 00:00:00 2001 From: Vivien Didelot Date: Thu, 30 Mar 2017 17:37:12 -0400 Subject: [PATCH] net: dsa: mv88e6xxx: factorize in-chip bridge map Factorize the code in the DSA port_bridge_{join,leave} routines used to program the port VLAN map of all local ports of a given bridge group. At the same time shorten the _mv88e6xxx_port_based_vlan_map to get rid of the old underscore prefix naming convention. Signed-off-by: Vivien Didelot Reviewed-by: Andrew Lunn Signed-off-by: David S.
