     As I understand it, FastPaths running KIP only propagate IP
broadcasts to the Ethernet.  Back when there weren't any AppleTalk hosts
on the Ethernet, it didn't make sense to put AppleTalk traffic on the
Ethernet.  NBPLookup requests on the AppleTalk network, for instance,
were answered by the FastPath, which used ARP on the Ethernet side to
find hosts that were not on the AppleTalk network.  I assume KIP still
works this way.
