a47ffec442 Call icmp_error() at the bottom of rip_input IFF rip_input is the handler 
for the protocol in the specified packet.
Fix statistic gathering to not make bogus increments of ips_delivered and
ips_noproto for cases where rip_input() is called by a protocol handler
(such as icmp_input or igmp_input) which has already processed the packet.

118d2b1d4f IPv6 kernel code, based on KAME/NetBSD 1.4, SNAP kit 19990628. 
(Sorry for a big commit, I can't separate this into several pieces...)
Pls check sys/netinet6/TODO and sys/netinet6/IMPLEMENTATION for details.

- sys/kern: do not assume single mbuf, accept chained mbuf on passing
  data from userland to kernel (or other way round).
- "midway" ATM card: ATM PVC pseudo device support, like those done in ALTQ
  package (ftp://ftp.csl.sony.co.jp/pub/kjc/).
- sys/netinet/tcp*: IPv4/v6 dual stack tcp support.
- sys/netinet/{ip6,icmp6}.h, sys/net/pfkeyv2.h: IETF document assumes those
  file to be there so we patch it up.
- sys/netinet: IPsec additions are here and there.
- sys/netinet6/*: most of IPv6 code sits here.
- sys/netkey: IPsec key management code
- dev/pci/pcidevs: regen

In my understanding no code here is subject to export control so it
should be safe.

a22cfcf3d4 Make programs that use raw IP work again; trim the header length from ip_len 
before handing the packet off to the socket.

30fcf99ef8 Fix a bug which would cause a panic in soreceive() if multiple raw

9df1988ac8 Implement the IP_RECVIF socket option: supply a datagram packet's incoming 
interface using a sockaddr_dl in a control mbuf.

Implement SO_TIMESTAMP for IP datagrams.

Move packet information option processing into a generic function
so that they work with multicast UDP and raw IP as well as unicast UDP.

59bbc2199e In rip_output(), sanity check the length of the packet to be transmitted. 
If it's larger than IP_MAXPACKET, return an error condition.

f90cf78fba convert pcb lists to CIRCLEQs, so that the end can be looked at more 
easily, and so that the original (insque/remque) logic can be effectively
mimiced.  (This fixes a bug in the previous set of list changes.)
also (since terminator is no longer null) reinstate uninitted list checks,
but mark them XXX.
