 * Name: mac802154_req_purge
 *
 * Description:
 *   The MCPS-PURGE.request primitive allows the next higher layer to purge
 *   an MSDU from the transaction queue. Confirmation is returned via
 *   the struct mac802154_maccb_s->conf_purge callback.
 *
 *   NOTE: The standard specifies that confirmation should be indicated via
 *   the asynchronous MLME-PURGE.confirm primitve.  However, in our
 *   implementation we synchronously return the status from the request.
 *   Therefore, we merge the functionality of the MLME-PURGE.request and
 *   MLME-PURGE.confirm primitives together.
