* The functions in this file handle management requests sent from
* user mode.
*
* Most of these functions have two separate blocks of code that are
* conditional on whether this is a station or an AP. This is used
* to separate out the STA and AP responses to these management primitives.
* It's a choice (good, bad, indifferent?) to have the code in the same
* place so it's clear that the same primitive is implemented in both
* cases but has different behavior.
