	The two ioctl() macros SIOCGARP and SIOCSARP are not defined in any of 
the include files. How to get the ethernet hardware address without these
macros ?  Even Richard Stevens' book avoided mentioning these macros. Is 
there any other way to get the hardware address ?  

	In fact, the above mentioned macros(with SS_ prefix, i.e., SS_SIOCGARP,
etc.) were found defined in a file:

		/usr/src/sys/i386/ibcs2/ibcs2_socksys.h

	When I included the above file and compiled my code it was pointing
out error in the include file.

		Any takers ?
