1. separating L2 tables (ARP, NDP) from the L3 routing tables
2. removing as much locking dependencies among these layers as
possible to allow for some parallelism in the search operations
3. simplify the logic in the routing code,
The most notable end result is the obsolescent of the route
cloning (RTF_CLONING) concept, which translated into code reduction
in both IPv4 ARP and IPv6 NDP related modules, and size reduction in
struct rtentry{}. The change in design obsoletes the semantics of
RTF_CLONING, RTF_WASCLONE and RTF_LLINFO routing flags. The userland
applications such as "arp" and "ndp" have been modified to reflect
those changes. The output from "netstat -r" shows only the routing
entries.
Quite a few developers have contributed to this project in the
past: Glebius Smirnoff, Luigi Rizzo, Alessandro Cerri, and
Andre Oppermann. And most recently:
- Kip Macy revised the locking code completely, thus completing
the last piece of the puzzle, Kip has also been conducting
active functional testing
- Sam Leffler has helped me improving/refactoring the code, and
provided valuable reviews
- Julian Elischer setup the perforce tree for me and has helped
me maintaining that branch before the svn conversion
to obtain correct netmask in case of interface with multiple aliases.

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.
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
interface would fail.
Remove global variables in favour of local ones.
Fix indentation of a couple of switch statements.
Overall, this program badly need cleaning up, as it relies
on information passed around through global variables.
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.

#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.)
