* @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.
