If the device is on a shared media, one thing we want to provide is 
pair-wise SAs to all other devices on the media.  This will automagically 
protect ARPs and any other MAC frames.

A specific solution to ARP is a mis-application of our resources.

A linksec solution that does not provide protection for ARPs has to be 
questioned as to its completeness.
