If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 58a547a24ce6f5917eaee965676eb57402998224 Author: Vladimir Oltean <vladimir.oltean@xxxxxxx> Date: Mon Jul 4 22:02:41 2022 +0300 net: dsa: felix: build as module when tc-taprio is module [ Upstream commit 10ed11ab6399813eb652137db9c378433c28a95c ] felix_vsc9959.c calls taprio_offload_get() and taprio_offload_free(), symbols exported by net/sched/sch_taprio.c. As such, we must disallow building the Felix driver as built-in when the symbol exported by tc-taprio isn't present in the kernel image.
