From db06ae41945b14feb7f696dcafe8048cc37e8a20 Mon Sep 17 00:00:00 2001 From: Andrew Lunn Date: Mon, 25 Sep 2017 23:32:20 +0200 Subject: net: dsa: mv88e6xxx: Allow dsa and cpu ports in multiple vlans Ports with the same VLAN must all be in the same bridge. However the CPU and DSA ports need to be in multiple VLANs spread over multiple bridges. So exclude them when performing this test.
