From 709643aa626ec8f0bd678be79187beefffae32c7 Mon Sep 17 00:00:00 2001 From: Vivien Didelot Date: Mon, 9 May 2016 13:22:52 -0400 Subject: [PATCH] net: dsa: mv88e6131: drop VLAN Ethertype setup The 6131 switch models have a Core Tag Type register. Their setup code is setting it to 0x8100, which is the reset default. Drop this specific part which is correctly configured on reset anyway. Signed-off-by: Vivien Didelot Signed-off-by: David S.
