[PATCH v2 05/14] rt2x00: rt2800lib: add hw_beacon_count field to struct rt2800_drv_data

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Gabor Juhos <juhosg@xxxxxxxxxxx>

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.
