From a058825fa7b53fab3b003d8928b60e5b686b3421 Mon Sep 17 00:00:00 2001

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.
