From 9b783763aa9623dedeed77bec158f7377cb87750 Mon Sep 17 00:00:00 2001 From: Michal Kazior Date: Thu, 21 Jan 2016 14:13:25 +0100 Subject: [PATCH] ath10k: add new FW_FEATURE_PEER_FLOW_CONTROL This feature flag will be used for firmware which supports pull-push model where host shares it's software queue state with firmware and firmware generates fetch requests telling host which queues to dequeue tx from. Primary function of this is improved MU-MIMO performance with multiple clients.
