Whoops, I should really have jumped into this thread earlier but somehow
missed it.

This cannot be converted to __set_bit because the IEEE specs mandate
this format.

We can insert a comment that the format must stay like this :)

You have to realise that the TIM is sent as-is with the 0th bit
indicating multicast traffic (IIRC) and each of the other bits
indicating traffic for that AID.
