From 9f34ad89bcf0e6df6f8b01f1bdab211493fc66d1 Mon Sep 17 00:00:00 2001 From: Jonas Gorski Date: Tue, 29 Apr 2025 22:17:09 +0200 Subject: net: dsa: b53: fix learning on VLAN unaware bridges When VLAN filtering is off, we configure the switch to forward, but not learn on VLAN table misses. This effectively disables learning while not filtering. Fix this by switching to forward and learn. Setting the learning disable register will still control whether learning actually happens.
