47 * The functions in this file handle management requests sent from
48 * user mode.
49 *
50 * Most of these functions have two separate blocks of code that are
51 * conditional on whether this is a station or an AP. This is used
52 * to separate out the STA and AP responses to these management primitives.
53 * It's a choice (good, bad, indifferent?) to have the code in the same
54 * place so it's clear that the same primitive is implemented in both
55 * cases but has different behavior.
