The use of an indication passed up from the datalink layer that indicates
whether the packet was sent to the datalink broadcast or not, while useful,
does not cover the entire problem. There are network configurations where, in 
effect, you do not have data link level packet addressing - for example, if
a network was built out of point to point links (slip, etc, etc). At a previous
company I worked at, we offered a product that allowed one to build TCP/IP
networks between mainframe hosts using serial point to point links. All 
addressing was carried in the IP header. ALL decisions as to the destination
of the packet were made SOLELY on the basis of the IP header.

I think that the preferred solution is to FIX the problem.
