31  * conditional on whether this is a station or an AP.  This is used
32  * to separate out the STA and AP responses to these management primitives.
33  * It's a choice (good, bad, indifferent?) to have the code in the same
34  * place so it's clear that the same primitive is implemented in both
35  * cases but has different behavior.
