7d26db1792 - Use time_uptime instead of time_second in data structures for
PF_INET6 in kernel.  This fixes various malfunction when the wall time
  clock is changed.  Bump __FreeBSD_version to 1000041.

- Use clock_gettime(CLOCK_MONOTONIC_FAST) in userland utilities.

9711a168b9 Retire struct sockaddr_inarp.
Since ARP and routing are separated, "proxy only" entries
don't have any meaning, thus we don't need additional field
in sockaddr to pass SIN_PROXY flag.

New kernel is binary compatible with old tools, since sizes
of sockaddr_inarp and sockaddr_in match, and sa_family are
filled with same value.

The structure declaration is left for compatibility with
third party software, but in tree code no longer use it.

a283298ce3 Improve flexibility of receiving Router Advertisement and
automatic link-local address configuration:

- Convert a sysctl net.inet6.ip6.accept_rtadv to one for the
  default value of a per-IF flag ND6_IFF_ACCEPT_RTADV, not a
  global knob.  The default value of the sysctl is 0.

- Add a new per-IF flag ND6_IFF_AUTO_LINKLOCAL and convert a
  sysctl net.inet6.ip6.auto_linklocal to one for its default
  value.  The default value of the sysctl is 1.

- Make ND6_IFF_IFDISABLED more robust.  It can be used to disable
  IPv6 functionality of an interface now.

- Receiving RA is allowed if ip6_forwarding==0 *and*
  ND6_IFF_ACCEPT_RTADV is set on that interface.  The former
  condition will be revisited later to support a "host + router" box
  like IPv6 CPE router.  The current behavior is compatible with
  the older releases of FreeBSD.

- The ifconfig(8) now supports these ND6 flags as well as "nud",
  "prefer_source", and "disabled" in ndp(8).  The ndp(8) now
  supports "auto_linklocal".

cb58c0efad In the NEXTADDR macro use SA_SIZE() rather than directly using
sizeof(), as introduced in r186119, for advancing the current
position into the buffer.
See comment in net/route.h for a description of the difference.

8eca593c5a This checkin addresses a couple of issues:
1. The "route" command allows route insertion through the interface-direct
   option "-iface". During if_attach(), an sockaddr_dl{} entry is created
   for the interface and is part of the interface address list. This
   sockaddr_dl{} entry describes the interface in detail. The "route"
   command selects this entry as the "gateway" object when the "-iface"
   option is present. The "arp" and "ndp" commands also interact with the
   kernel through the routing socket when adding and removing static L2
   entries. The static L2 information is also provided through the
   "gateway" object with an AF_LINK family type, similar to what is
   provided by the "route" command. In order to differentiate between
   these two types of operations, a RTF_LLDATA flag is introduced. This
   flag is set by the "arp" and "ndp" commands when issuing the add and
   delete commands. This flag is also set in each L2 entry returned by the
   kernel. The "arp" and "ndp" command follows a convention where a RTM_GET
   is issued first followed by a RTM_ADD/DELETE. This RTM_GET request fills
   in the fields for a "rtm" object, which is reinjected into the kernel by
   a subsequent RTM_ADD/DELETE command. The entry returend from RTM_GET
   is a prefix route, so the RTF_LLDATA flag must be specified when issuing
   the RTM_ADD/DELETE messages.

2. Enforce the convention that NET_RT_FLAGS with a 0 w_arg is the
   specification for retrieving L2 information. Also optimized the
   code logic.

6e6b3f7cbc This main goals of this project are:
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

07cf047d5a introduced a flag bit "ND6_IFF_ACCEPT_RTADV" in the nd_ifinfo structure to
control whether to accept RAs per-interface basis.
the new stuff ensures the backward compatibility;
- the kernel does not accept RAs on any interfaces by default.
- since the default value of the flag bit is on, the kernel accepts RAs
  on all interfaces when net.inet6.ip6.accept_rtadv is 1.
