ad9d3794b0 Implement support for IP/TCP/UDP checksum offloading provided by 
network interfaces.  This works by pre-computing the pseudo-header
checksum and caching it, delaying the actual checksum to ip_output()
if the hardware cannot perform the sum for us.  In-bound checksums
can either be fully-checked by hardware, or summed up for final
verification by software.  This method was modeled after how this
is done in FreeBSD, although the code is significantly different in
most places.

We don't delay checksums for IPv6/TCP, but we do take advantage of the
cached pseudo-header checksum.

Note: hardware-assisted checksumming defaults to "off".  It is
enabled with ifconfig(8).  See the manual page for details.

Implement hardware-assisted checksumming on the DP83820 Gigabit Ethernet,
3c90xB/3c90xC 10/100 Ethernet, and Alteon Tigon/Tigon2 Gigabit Ethernet.

XXX is eon_rtrequest() change correct regarding to 3rd arg?
eon_rtrequest() and rtrequest() were incorrect since 4.3BSD-reno,
so i do not have correct answer in the source code.

  route entries.
- if the traffic was not validated by xx_ctlinput, allow up to "lowat" pmtud
  route entries (there's upper limit, so bad guys cannot blow up our routing

65fd25ea82 Restructure the PFIL_HOOKS mechanism a bit: 
- All packets are passed to PFIL_HOOKS as they come off the wire, i.e.
  fields in protocol headers in network order, etc.
- Allow for multiple hooks to be registered, using a "key" and a "dlt".
  The "dlt" is a BPF data link type, indicating what type of header is
  present.
- INET and INET6 register with key == AF_INET or AF_INET6, and
  dlt == DLT_RAW.
- PFIL_HOOKS now take an argument for the filter hook, and mbuf **,
  an ifnet *, and a direction (PFIL_IN or PFIL_OUT), thus making them
  less IP (really, IP Filter) centric.

Maintain compatibility with IP Filter by adding wrapper functions for
IP Filter.

ea9b5a9106 Restructure the Path MTU Discovery code somewhat to avoid 
entering rtentry's for hosts we're not actually communicating
with.

Do this by invoking the ctlinput for the protocol, which is
responsible for validating the ICMP message:
	* TCP -- Lookup the connection based on the address/port
	  pairs in the ICMP message.
	* AH/ESP -- Lookup the SA based on the SPI in the ICMP message.

If validation succeeds, ctlinput is responsible for calling
icmp_mtudisc().  icmp_mtudisc() then invokes callbacks registered
by protocols (such as TCP) which want to take some sort of special
action when a path's MTU changes.  For TCP, this is where we now
refresh cached routes and re-enter slow-start.

As a side-effect, this fixes the problem where TCP would not be
notified when a path's MTU changed if AH/ESP were being used.

XXX Note, this is only a fix for the IPv4 case.  For the IPv6
XXX case, we need to wait for the KAME folks.

- 4.4BSD did not check return code from in_ifinit() at all.
  4.4BSD does not support multiple address from same prefix.
- past KAME change passed in{,6}_ifinit() to upwards, toward ifconfig(8).
  the behavior is filed as PR 10427.
- the commit inhibits EEXIST from rtinit(), hence partially recovers old
  4.4BSD behavior.
- the right thing to happen is to properly support multiple address assignment
  from the same prefix.  KAME tree has more extensive change, however, it needs
  much more time to get stabilized (rtentry refcnt change can cause serious
  issue, we really need to bake it before bring it to netbsd)

92e64a4a0d sync with almost-latest KAME IPsec. full changelog would be too big 
to mention here.  notable changes are like below.

kernel:
- make PF_KEY kernel interface more robust against broken input stream.
  it includes complete internal structure change in sys/netkey/key.c.
- remove non-RFC compliant change in PF_KEY API, in particular,
  in struct sadb_msg.  we cannot just change these standard structs.
  sadb_x_sa2 is introduced instead.
- remove prototypes for pfkey_xx functions from /usr/include/net/pfkeyv2.h.
  these functions are not supplied in /usr/lib.

setkey(8):
- get/delete does not require "-m mode" (ignored with warning, if you
  specify it)
- spddelete takes direction specification

4308599c5a disallow bind(2) with IPv4 mapped address for now. port number check is 
insufficient at this moment and we can bind(2) two sockets listen on same
port number.

for real fix, we need to check inpcb table with in6pcb.  we can't
find inpcb chain from particular in6pcb chain (like finding tcbtable from tcb6)
luckily RFC2553 does not talk about bind(2) behavior for IPv4 mapped.
IPv4 mapped brings in too much complexities...

fa5c89d64a do not mistakingly forward link-local scoped packet (the bug was added 
with "beyondscope" icmp6 support).
"options FAKE_LOOPBACK_IF" will honor scope on loopback outputs.  rcvif will
be real interface, not the loopback, just like when multicast loopback.

there are too many protocol specs for ip proto #4/41.
backward compatibility with MROUTING case is now provided in ip_encap.c.

fix ipip to work with gif (using ip_encap.c).  sorry for breakage.

gif now uses ip_encap.c.

with ip proto #41).
