From 8ae861221042057b8a986cd0a47ecf88bd2fc2b2 Mon Sep 17 00:00:00 2001 From: Robert Marko Date: Sun, 13 Aug 2023 15:58:47 +0200 Subject: [PATCH] ipq40xx: qca8k: add ageing setting support qca8k driver we are currently based of is rather out of date and is lacking support for setting the ageing time or fast ageing so until we update the driver lets just backport support for those from qca8k.
