+ mac80211: fix crash on getting sta info with uninitialized rate control
+
+ If the expected throughput is queried before rate control has been
+ initialized, the minstrel op for it will crash while trying to access
+ the rate table.
+ Check for WLAN_STA_RATE_CONTROL before attempting to use the rate
+ control op.
