Subject: iwlwifi: Check BSS ctx active before call mac80211
From: Ilan Peer <[email protected]>
commit e19ebcab01cc130fa832764d453b263460ec3b91 upstream.
It is possible that the BSS context is not active (for example
when the current mode is set to GO), or that the vif->type is
different than station. In such a case we cannot
call mac80211 to report the average rssi for the interface
(the function assumes that the vif is valid and that the type
is station).
