  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.
