 *  @brief Private IOCTL entry to send an ADDTS TSPEC
 *
 *  Receive a ADDTS command from the application.  The command structure

 *
 *  The TSPEC is received in the API as an opaque block. The firmware will
 *    send the entire data block, including the bytes after the TSPEC.  This
 *    is done to allow extra IEs to be packaged with the TSPEC in the ADDTS
 *    action frame.
 *
 *  The IOCTL structure contains two return fields:
 *    - The firmware command result, which indicates failure and timeouts
 *    - The IEEE Status code which contains the corresponding value from
 *      any ADDTS response frame received.
 *
 *  In addition, the opaque TSPEC data block passed in is replaced with the
 *    TSPEC received in the ADDTS response frame.  In case of failure, the
 *    AP may modify the TSPEC on return and in the case of success, the
 *    medium time is returned as calculated by the AP.  Along with the TSPEC,
 *    any IEs that are sent in the ADDTS response are also returned and can be
 *    parsed using the IOCTL length as an indicator of extra elements.
 *
 *  The return value to the application layer indicates a driver execution
 *    success or failure.  A successful return could still indicate a firmware
 *    failure or AP negotiation failure via the commandResult field copied
 *    back to the application.
