From 3a53731df7e2a6e238274d13aa8d4826f78030f9 Mon Sep 17 00:00:00 2001 From: "Pedersen, Thomas" Date: Wed, 28 Sep 2016 16:56:31 -0700 Subject: [PATCH] mac80211: mesh: decrease max drift The old value was 30ms, which means mesh sync will treat any value below as merely TSF drift. This isn't really reasonable (typical drift is < 10us/s) since people probably want to adjust TSF in smaller increments (for ie. beacon collision avoidance) without mesh sync fighting back. Change max drift adjustment to 0.8ms, so manual TSF adjustments can be made in 1ms increments, with some margin.
