From 973324fff154beb51711136d5d242df7f328f708 Mon Sep 17 00:00:00 2001 From: "Pedersen, Thomas" Date: Wed, 28 Sep 2016 16:56:29 -0700 Subject: [PATCH] ath10k: implement offset_tsf ieee80211_op Current set_tsf is implemented in terms of TSF_INCREMENT only. Instead support new WMI command TSF_DECREMENT and export these through offset_tsf. Advantage is we get more accurate TSF adjustments, and don't calculate wrong offset in case absolute TSF was calculated from rx_mactime (actual TSF). The new WMI command is available in firmware 10.4-3.2.1-00033 for QCA4019 chips. Old drivers on new firmware or vice versa shouldn't be a problem since get/set tsf logic was already broken.
