I think it is possible to collapse your rt2800 related patch and this
patch with a single patch only touching generic rt2x00 code.
We could use the max_ap_intf field of the rt2x00_ops struct to
determine the mask in a generic manner.
So, we could have the following statement in generic code (e.g. in
rt2x00lib_probe_dev):
rt2x00dev->hw->wiphy->addr_mask[ETH_ALEN - 1] =
(rt2x00dev->ops->max_ap_intf - 1);
