     *   Encode memory with an Atheros vendor specific message header
     *   having HomePlug message protocol version (INTELLON_MMV) and
     *   Atheros message type (MMTYPE);
     *
     *   return the number of bytes actually encoded or 0 on encode error;
     *   the error code is stored in errno;
     *
     *   see the INT6000 Firmware Technical Reference Manual for more
     *   about MME headers and message types; the Atheros OUI is
     *   implicit in this function;
     *
     *   MMV is the version number of the MME command set; currently,
     *   there is only one command set for Atheros MMEs;
     *
     *   MMTYPE indicates the desired Atheros device operation taken
     *   from the TRM; some operations are undocumented and should not
     *   be used;
     *
     *   OUI is the Organizationally Unique Identifier resgistered with
     *   the IEEE by the vendor and is a constant for Atheros Devices;
     *
     *   There is no need to flush the header since this function writes
     *   to all locations unless there is an error; the caller may elect
     *   to flush the buffer before calling this function;
