* 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;
