Why?

Please include an example how to use the debugfs file.

IIRC there was a similar rtw88 patch adding a debugfs to force setting
the tx rate. So what's the consensus, are we going to allow each driver
have their own custom interfaces setting tx rates? In my opinion this
should go via a generic nl80211 command, but if people think having
custom tx rate interfaces is ok I guess I need to reconsider.

As this patch needs more discussion, please separate it from rest of the
series so that it can be applied separately.
