- *
- * 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.
