From b723dbb313f09d238738dae5efd6d7c52f0fe25e Mon Sep 17 00:00:00 2001 From: Lubomir Rintel Date: Sun, 10 Feb 2019 20:48:22 +0100 Subject: [PATCH] libertas_tf: fix signal reporting Instead of exposing the signal-to-noise ration, calculate the actual signal level taking the noise floor into account. Also, flip the SIGNAL_DBM bit on, so that mac80211 exposes the signal level along with the station info in scan results. This fills NetworkManager's "nmcli d wifi output" output with colors, bars and joy.
