06274cee44 - Before doing ioctl(SIOCGIFNETMASK) put the proper IP address into the ifreq, 
to obtain correct netmask in case of interface with multiple aliases.
- While here, remove a comment with a bad idea.

68839124b6 Massive cleanup of the code removing global variables to 
pass function arguments and results.

Hopefully no functional changes except fixing a couple of
bugs which could cause endless loops if an ioctl() on an

b9de94e9eb Implement a new option: -i, which will allow to limit 
the scope of operation to the ARP entries on a particular
interface.  It should be useful on machines with numerous
network interfaces, e.g., on inter-VLAN routers.

2ab778e1d3 Unbreak this file after the last drive-by committing. We have to 
#include route.h before iso88025.h, and we have to dereference
the trld_route array correctly. (NOTE: I'm not altogether sure
that this is really the correct way to traverse this array. This
just eliminates the build warning/error. It may not work right at
runtime, and I have no way to test it since I lack the necessary
hardware.)

3f844a2221 - Renamed the `proxy'' modifier of the -d flag to `pub'', 
to be consistent with the -s flag.  Updated documentation
  on what this modifier does.

- Added the ``only'' keyword to the -s and -S flags, that
  could be used to created "proxy-only" published entries.
  Previously, arp(8) created an entry of this type only
  in the absence of the route to a destination.
