MAX_HEADER does not include the ipv6 header length in it,
so we need to add it in explicitly.

If inet6_init() fails later than ndisc_init() call, or IPv6 module is
unloaded, ndisc_netdev_notifier call remains in the list and will follows in
oops later.

We did not send appropriate IsRouter flag if the forwarding setting is
positive even value. Let's give 1/0 value to ndisc_send_na().
Also, existing users of ndisc_send_na() give 0/1 to override,
we can omit redundant operation in that function.

We have sent NA with router flag from the node-wide forwarding
configuration. This is not appropriate for proxy NA, and it should be
set according to each proxy entry's configuration.
This is used by Mobile IPv6 home agent to support physical home link
in acting as a proxy router for mobile node which is not a router,
for example.

This aims at proxying router not updating neighbor cache entry for proxied
address when it receives NA because either the proxied node is off link or
it has already sent a NA to the proxied router.

This labels the flows that could utilize IPSec xfrms at the points the
flows are defined so that IPSec policy and SAs at the right label can
be used.
The following protos are currently not handled, but they should
continue to be able to use single-labeled IPSec like they currently
do.

There are errors and inconsistency in the display of NIP6 strings.
ie: net/ipv6/ip6_flowlabel.c
There are errors and inconsistency in the display of NIPQUAD strings too.
ie: net/netfilter/nf_conntrack_ftp.c
This patch:
adds NIP6_FMT to kernel.h
changes all code to use NIP6_FMT
fixes net/ipv6/ip6_flowlabel.c
adds NIPQUAD_FMT to kernel.h
fixes net/netfilter/nf_conntrack_ftp.c
changes a few uses of "%u.%u.%u.%u" to NIPQUAD_FMT for symmetry to NIP6_FMT

Timer set up by pneigh_enqueue() ended up calling ndisc_rcv()
via pndisc_redo(), which clears LOCALLY_ENQUEUED flag in
NEIGH_CB(skb) and NS was queued again.
Let's call ndisc_recv_ns() directly to avoid the loop.

Essentially netlink at the moment always reports a pid and sequence of 0
always for v6 route activities.
To understand the repurcassions of this look at:
http://lists.quagga.net/pipermail/quagga-dev/2005-June/003507.html
While fixing this, i took the liberty to resolve the outstanding issue
of IPV6 routes inserted via ioctls to have the correct pids as well.
This patch tries to behave as close as possible to the v4 routes i.e
maintains whatever PID the socket issuing the command owns as opposed to
the process. That made the patch a little bulky.
I have tested against both netlink derived utility to add/del routes as
well as ioctl derived one. The Quagga folks have tested against quagga.
This fixes the problem and so far hasnt been detected to introduce any
new issues.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
