[PATCH 4.4 04/86] iwlwifi: mvm: support sta_statistics() even on older firmware

[Greg Kroah-Hartman]

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Emmanuel Grumbach <emmanuel.grumbach@xxxxxxxxx>

commit ec484d03ef0df8d34086b95710e355a259cbe1f2 upstream.

The oldest firmware supported by iwlmvm do support getting
the average beacon RSSI. Enable the sta_statistics() call
from mac80211 even on older firmware versions.
