From 5533513784a88049e19dd2ab380a452b61e5171e Mon Sep 17 00:00:00 2001 From: Ashok Nagarajan Date: Tue, 28 Feb 2012 17:04:08 -0800 Subject: {nl,cfg,mac}80211: Implement RSSI threshold for mesh peering Mesh peer links are established only if average rssi of the peer candidate satisfies the threshold. This is not in 802.11s specification but was requested by David Fulgham, an open80211s user. This is a way to avoid marginal peer links with stations that are barely within range. This patch adds a new mesh configuration parameter, mesh_rssi_threshold. This feature is supported only for hardwares that report signal in dBm.

This can be passed in NL80211_CMD_START_AP and used by the drivers which have AP MLME in firmware but don't support get_station() properly. To disable inactivity timer in userspace, wpa_s for example, there is a new flag, NL80211_FEATURE_INACTIVITY_TIMER, in nl80211_feature_flags through which drivers can register their capability to use the inactivity timeout to free the stations.
