+    ath9k_hw: remove ANI function restrictions for AP mode
+    
+    The primary purpose of this piece of code was to selectively disable
+    OFDM weak signal detection. The checks for this are elsewhere, and an
+    earlier commit relaxed the restrictions for older chips, which are more
+    sensitive to interference.
