 * Module:	etheraddr
 * Description:	This is the solaris-specific interface for retrieving
 *		the MAC (IEEE 802.3) node identifier, a.k.a. the ethernet
 *		address of the system.  Note that this can only get the
 *		ethernet address if the process running the code can open
 *		/dev/[whatever] read/write, e.g. you must be root.
