Of course.  Isn't that why it's a macro and then isn't memcpy the best way
to guarantee a successful port?  If someone needs the speed, this is one of
the first places to optimize.  It's why I brought up the idea of macros
solely for IP and MAC address copies (as they were known to be 4 and 6 bytes
and better inlined manually on some platforms).  Naturally, I'm all for
changing defaults to improve overall performance. :-)
