I don't understand.

The point is - you're setting the bit in the beacon that indicates "I'm
transmitting it as duplicate", right?

But you're also using that bit to actually configure it to do (non-HT)
duplicate transmissions.

But fundamentally, those two things aren't really related, are they? Why
shouldn't you be - at least theoretically - be able to configure it for
duplicate transmission (or not) regardless of the bit in the beacon?

To me it seems "do duplicate transmission" is a property of the *rate*
you want to use to transmit, not really necessarily a property of the
*content* of the frame you're transmitting.
