From 354d381baf1126c45d03b5c0d87d22caf938b86b Mon Sep 17 00:00:00 2001 From: "Pedersen, Thomas" Date: Wed, 28 Sep 2016 16:56:28 -0700 Subject: mac80211: add offset_tsf driver op and use it for mesh This allows the mesh sync (and debugfs) code to make incremental TSF adjustments, avoiding any uncertainty introduced by delay in programming absolute TSF.
