 *
 *   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;
