From d51c542b782fac35a9f37a23391f3bee884b7401 Mon Sep 17 00:00:00 2001 From: Vivien Didelot Date: Mon, 18 Jul 2016 20:45:29 -0400 Subject: [PATCH] net: dsa: mv88e6xxx: remove basic function flags All 88E6xxx Marvell switches (even the old not supported yet 88E6060) have at least an ATU, per-port STP states and VLAN map, to run basic switch functions such as Spanning Tree and port based VLANs. Get rid of the related MV88E6XXX_FLAG_{ATU,PORTSTATE,VLANTABLE} flags, as they are defaults to every chip. This enables STP on 6185 and removes many inconsistencies on others.
