+Subject: [PATCH] rt2x00: rt2800lib: add hw_beacon_count field to struct
+ rt2800_drv_data
+
+Some chipsets can handle more than 8 beacons at once.
+Add a new field to the rt2800_drv_data structure which
+will hold the number of supported beacons of the given
+chipset.
+
+Update the rt2x00_init_registers function to get the
+beacon count from the new field instead of using a
+hardcoded value.
+
+In order to keep the current behaviour, initialize the
+new field with the actually used value.
