From e39d14a760c039af0653e3df967e7525413924a0 Mon Sep 17 00:00:00 2001 From: Jonas Gorski Date: Sat, 10 May 2025 11:22:11 +0200 Subject: net: dsa: b53: implement setting ageing time b53 supported switches support configuring ageing time between 1 and 1,048,575 seconds, so add an appropriate setter. This allows b53 to pass the FDB learning test for both vlan aware and vlan unaware bridges.
