+    ath9k: do not set half/quarter channel flags in AR_PHY_MODE
+    
+    5/10 MHz channel bandwidth is configured via the PLL clock, instead of
+    the AR_PHY_MODE register. Using that register is AR93xx specific, and
+    makes the mode incompatible with earlier chipsets.
+    
+    In some early versions, these flags were apparently applied at the wrong
+    point in time and thus did not cause connectivity issues, however now
+    they are causing problems, as pointed out in this OpenWrt ticket:
