cfg80211: Pass new RSSI level in CQM RSSI notification

Browse source

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.
