1904ffad56 - 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.

d4826e3f0a MFC 1.18 - 1.21: 
- Document last change to ARP behavior.
  - Document several undocumented sysctl variables.
  - Fix spelling of few diagnostics.
  - Improve the documentation of "proxyall" knob, somewhat: we do not
    proxy for hosts that are reachable through the same interface the
    request came in from.  This feature is mainly for hosts reachable
    through some P2P link, e.g. the gif(4) tunnel.

7a125692f3 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

e91a5a8a8f 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.

91b9756f6b 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.)
