From 8f5d16f638b9a1adf544a7f8cfd11ac1c01c6e25 Mon Sep 17 00:00:00 2001 From: Vladimir Oltean Date: Sun, 28 Apr 2019 21:45:44 +0300 Subject: net: dsa: Be aware of switches where VLAN filtering is a global setting On some switches, the action of whether to parse VLAN frame headers and use that information for ingress admission is configurable, but not per port. Such is the case for the Broadcom BCM53xx and the NXP SJA1105 families, for example. In that case, DSA can prevent the bridge core from trying to apply different VLAN filtering settings on net devices that belong to the same switch.
