From 0103c34fed88414808dfbc500b9066ab867e3b6c Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Thu, 18 Feb 2016 19:49:18 +0100 Subject: [PATCH] mac80211: minstrel_ht: set default tx aggregation timeout to 0 commit 7a36b930e6ed4702c866dc74a5ad07318a57c688 upstream. The value 5000 was put here with the addition of the timeout field to ieee80211_start_tx_ba_session. It was originally added in mac80211 to save resources for drivers like iwlwifi, which only supports a limited number of concurrent aggregation sessions. Since iwlwifi does not use minstrel_ht and other drivers don't need this, 0 is a better default - especially since there have been recent reports of aggregation setup related issues reproduced with ath9k. This should improve stability without causing any adverse effects.
