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
POSIX. This also makes the struct correct we ever implement an i386-time64
architecture. Not that we need too.

While I'm here, rearrange the synopsis a bit: sort the options and
clarify that -i and -s are mutually exclusive.

refers to the size of the whole ethernet packet, just the DHCP
message within the UDP payload, or something else. bootpd interpreted
it as a maximum UDP payload size, so it could end up sending
fragmented packets to clients (such as some versions of Etherboot)
that used different interpretations of the maximum message size.
Switch to the most conservative interpretation: ensure that the
ethernet packet containing the response is no larger than the
specified maximum message size. This matches the behaviour of
the ISC dhcpd.

bptypes.h originally defined int32 to be of type long. This obviously
doesn't work on the Alpha. By defining int32 (and u_int32) in terms of
int32_t (and u_int32_t) it now is what it says it should be.
Two occurrences of 'unsigned int32' have been changed to 'u_int32' for
consistency.
