From bee427b86217b78a0a5fc85575cc155e4c32bbf9 Mon Sep 17 00:00:00 2001 From: Andrzej Zaborowski Date: Wed, 25 Jan 2017 12:43:41 +0100 Subject: cfg80211: Pass new RSSI level in CQM RSSI notification Update the drivers to pass the RSSI level as a cfg80211_cqm_rssi_notify parameter and pass this value to userspace in a new nl80211 attribute. This helps both userspace and also helps in the implementation of the multiple RSSI thresholds CQM mechanism. Note for marvell/mwifiex I pass 0 for the RSSI value because the new RSSI value is not available to the driver at the time of the cfg80211_cqm_rssi_notify call, but the driver queries the new value immediately after that, so it is actually available just a moment later if we wanted to defer caling cfg80211_cqm_rssi_notify until that moment. Without this, the new cfg80211 code (patch 3) will call .get_station which will send a duplicate HostCmd_CMD_RSSI_INFO command to the hardware.
