From: Tamizh chelvam <tamizhr@codeaurora.org>

Currently station mode has the support of rssi based cqm. This patchsets
extended the support for AP mode as well. Already netlink accepts mac
address in cqm notification event. We can use that to pass mac address of
the station to specify its rssi change event. This patchsets introduce
new api cfg80211_ap_sta_cqm_notify and multicast group to notify the event.

  cfg80211: enable setting cqm rssi config for AP mode
  mac80211: implement cqm rssi check using rx data signal

v3:
  * Added vif type check to avoid enable this feature for all mode.

V2:
  * Removed changing existing ieee80211_cqm_rssi_notify api changes.
  * Introduced new ext feature bit and multicast group id to support this
    feature.

From: Tamizh chelvam <tamizhr@codeaurora.org>

This patch extend cqm rssi config and notifier feature to AP mode
by introducing NL80211_EXT_FEATURE_AP_STA_CQM_RSSI_CONFIG ext
feature bit. And this patch introduces NL80211_MCGRP_AP_STA_CQM
for notifying station's low/high rssi event to userspace application.

From: Tamizh chelvam <tamizhr@codeaurora.org>

Triggers cfg80211_ap_sta_cqm_rssi_notify with the corresponding event
when station signal goes lower than the configured rssi threshold. And
notify back to user space once the station signal becomes greater than
the configured value. It uses rx data signal and compare with rssi value
given by user. This rssi threshold is bss specific and it is common for
all the stations.
