From 4b965be536eefdd16ca0a88120fee23f5b92cd16 Mon Sep 17 00:00:00 2001 From: Karthikeyan Periyasamy Date: Mon, 8 Feb 2021 13:32:11 +0200 Subject: ath11k: Update tx descriptor search index properly 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.
