a good idea. Instead hand the work off expiring interface addresses off
to a taskq. Fixes the "p->p_wchan == NULL" panics seen with usb ethernet
adapters.

above the reroute label that pf uses after it does dest addr rewriting
on outgoing packets. previously rerouting caused an extra copy to
be allocated, which caused the first copy to be leaked.
this has been bugging me for over half a year probably. after i got
some rudimental mbuf tracing in place it took me and alex wilson
most of a work day to audit the stack.

are are lie, since the software engine emulates hardware offloading
and that is later indistinguishable. so kill the hw cksummed counters.
introduce software checksummed packet counters instead.
tcp/udp handles ip & ipvshit, ip cksum covered, 6 has no ip layer cksum.
as before we still have a miscounting bug for inbound with pf on, to be
fixed in the next step.

(unplugged). Even if it makes no sense to keep them around if the
interface is no more, we cannot safely remove them since pcb multicast
options might keep a pointer to them.

Really change the link-local address in the unlikely event of an IFID
collision, instead of going into an infinite conf-nak loop with the peer.
To make the netinet6 code use the IPv6CP IFID in a new link-local address,
in6_ifattach_linklocal() must accept a provided IFID. Replace the unused
'altifp' parameter with a new 'ifid' parameter for this purpose.
Always use the latest suggested address in IPv6CP replies, even if
the task to update the interface's address hasn't run yet.
Also, clear the ifindex (KAME hack) in addresses sent during IPv6CP.

Instead of linking multicast records to the first configured address of
the corresponding protocol, making this address and its position in the
global list special, add them to a new list directly linked to the
interface descriptor.
This new multicast address list is similar to the address list, all its
elements contain a protocol agnostic part. This design allows us to
be able to join a multicast group without necessarily having a configured
address. That means IPv6 multicast kludges are no longer needed.
Another benefit is to be able to add and remove an IP address from an
interface without worrying about multicast records. That means that the
global IPv4 list is no longer needed since the first configured address
of an interface is no longer special.
This new list might also be extended in the future to contain the
link-layer addresses used to configure hardware filters.

divert6_packet() from "pd" to "divert" to match the rest of the source.
I think "pd" was not a good name for a struct pf_divert because "pd"
usually refers to a pf_pdesc.
No object file change.

stack should still scan for IPv6 type 0 routing headers. There are
OpenBSD routers running without pf and there are plenty of legacy
implementations supporting RH0.
Bring back the function ip6_check_rh0hdr() that I removed a month
ago. As an improvement to the prevoius solution, only scan the
header chain in ip6_input() if the packet has not been inspected
by pf. Both implementations drop packets with RH0 anywhere in the
extension header chain.

is marked as NODAD.
Since we're not gonna do duplicate address detection for this address,
the TENTATIVE flag won't get cleared, rendering the address unusable.
The existing logic only checked whether DAD was enabled for the interface,
but DAD can be configured on a per-address basis.

One worrying bit is in icmp6.h where some htols() and htonl() are
added, which may affect compatibility down the line. This component
can be reverted if issues show up. Ports tree greps indicate no issue.
