From 111b49902465116a8353d29afe02eff0f56ea0a3 Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Thu, 16 Nov 2017 09:57:13 +0100 Subject: [PATCH] mac80211: tweak TSQ settings Latencies can be much higher on wifi devices, especially with aggregation. Tune the network stack setting introduced in the previous commit to account for that.
