[PATCH net v2 1/5] net: dsa: b53: Lookup VID in ARL searches when VLAN is enabled
From: Florian Fainelli
Date: Mon Apr 20 2020 - 23:27:56 EST
When VLAN is enabled, and an ARL search is issued, we also need to
compare the full {MAC,VID} tuple before returning a successful search
result.
Fixes: 1da6df85c6fb ("net: dsa: b53: Implement ARL add/del/dump operations")
