BTW after you have reviewed the patch, and you think the patch is ok, you could reply with: Reviewed-by: Peter Oh <peter.oh@eero.com> Patchwork automatically picks up that and then it would be an indication for me that the patch is ready to be applied. I like the Reviewed-by tag a lot as then I can see that others have also reviewed the patch. -- https://patchwork.kernel.org/project/linux-wireless/list/ https://wireless.wiki.kernel.org/en/developers/documentation/submittingpatches

Tx descriptor search index field should be updated with hw peer id and not by AST Hash as per the HW/FW recommendation. Incorrect search index causes throughput degradation in all scenario for all the platforms. so updated the search index field with hw peer id, which is a common change applicable for all the platforms. Also no need of these configuration for non station type. seen 10% throughput increase in WDS traffic with this change.
