From 8efdda4a1b609ac40c4729109215f9c77f938fdc Mon Sep 17 00:00:00 2001 From: Vivien Didelot Date: Thu, 13 Aug 2015 12:52:23 -0400 Subject: [PATCH] net: dsa: mv88e6xxx: use port 802.1Q mode Secure This commit changes the 802.1Q mode of each port from Disabled to Secure. This enables the VLAN support, by checking the VTU entries on ingress. Signed-off-by: Vivien Didelot Signed-off-by: David S.
