By this change, nexthop caches (IP-MAC address pair) are not stored
in the routing table anymore. Instead nexthop caches are stored in
each network interface; we already have lltable/llentry data structure
for this purpose. This change also obsoletes the concept of cloning/cloned
routes. Cloned routes no longer exist while cloning routes still exist
with renamed to connected routes.
Noticeable changes are:
- Nexthop caches aren't listed in route show/netstat -r
- sysctl(NET_RT_DUMP) doesn't return them
- If RTF_LLDATA is specified, it returns nexthop caches
- Several definitions of routing flags and messages are removed
- RTF_CLONING, RTF_XRESOLVE, RTF_LLINFO, RTF_CLONED and RTM_RESOLVE
- RTF_CONNECTED is added
- It has the same value of RTF_CLONING for backward compatibility
- route's -xresolve, -[no]cloned and -llinfo options are removed
- -[no]cloning remains because it seems there are users
- -[no]connected is introduced and recommended
to be used instead of -[no]cloning
- route show/netstat -r drops some flags
- 'L' and 'c' are not seen anymore
- 'C' now indicates a connected route
- Gateway value of a route of an interface address is now not
a L2 address but "link#N" like a connected (cloning) route
- Proxy ARP: "arp -s ... pub" doesn't create a route
You can know details of behavior changes by seeing diffs under tests/.

XEN3_DOM0. Thanks!
XXX pull-up netbsd-7
This patch fixes "ipfstat" not displaying group rules and fixes problems
being able to remove individual rules using ipf/ipnat.
#547 rule parsing puts junk at the end of ipf rules
#546 ipfstat -io does not list rules in groups aside from 0
Due to unforeseen circumstances I'm not able to commit this myself.

is "undefined", according to C99 6.10.1 note 4. So, change code like
that to use the following paradigm
#if defined(BAR)
#define FOO 1
#else
#define FOO 0
#endif
#if FOO
[conditional code]
#endif
