Update of /cvsroot/src/sys/netinet
In directory nb00:/tmp/cvs-serv18454

Modified Files:
        if_arp.c in_var.h 
Log Message:
The rewrite of if_arp.c to work with the hashed interface address lists
(1.44) missed a test for the right interface, making some machines answer
to some bogus arp requests (like for WHO-HAS 127.0.0.1).

The quick patch in 1.46-1.47 does not work for so-called "unnumbered"
interfaces, that is, (point-to-point) interfaces that share their local
address with another (e.g., the Ethernet) interface.

We add a macro to in_var.h, to step (in the current implementation) through
the hash chain and fine more entries with the same address, and use that
in if_arp.c to find one which belongs to our interface.
