Subject: [PATCH] net: dsa: mv88e6xxx: Allow dsa and cpu ports in multiple
vlans
Git-commit: db06ae41945b14feb7f696dcafe8048cc37e8a20
References: git-fixes
Patch-mainline: v4.14-rc4
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.
Fixes: b2f81d304cee ("net: dsa: add CPU and DSA ports as VLAN members")
