linux.git/drivers/net/wireless/rsi, branch v4.12 Linux kernel source tree wireless: Set NL80211_EXT_FEATURE_CQM_RSSI_LIST in multiple drivers 2017-03-06T08:21:39+00:00 Andrew Zaborowski andrew.zaborowski@intel.com 2017-02-10T03:50:23+00:00 ae44b502669d0cd1f167cdb48994292aa20fd3dd Set the NL80211_EXT_FEATURE_CQM_RSSI_LIST wiphy extended feature wholesale in all mac80211-based drivers that do not set the IEEE80211_VIF_BEACON_FILTER flags on their interfaces. mac80211 will be processing supplied RSSI values in ieee80211_rx_mgmt_beacon and will detect when the thresholds set by ieee80211_set_cqm_rssi_range_config are crossed. Remaining (few) drivers need code to enable the firmware to monitor the thresholds. This is mostly only compile-tested.

mac80211: Pass new RSSI level in CQM RSSI notification 2017-02-08T09:43:04+00:00 Andrzej Zaborowski andrew.zaborowski@intel.com 2017-01-25T11:43:40+00:00 769f07d8f0fb6a68a0eda6308bbe890bff894fd7 Extend ieee80211_cqm_rssi_notify with a rssi_level parameter so that this information can be passed to netlink clients in the next patch, if available. Most drivers will have this value at hand. wl1251 receives events from the firmware that only tell it whether latest measurement is above or below threshold so we don't pass any value at this time (parameter is 0).
