itojun 4d51fe368b change the meaning of ifnet.if_lastchange to meet RFC1573 ifLastChange.
follows BSD/OS practice and ucd-snmp code (FreeBSD does it for specific
interfaces only).

was: if_lastchange get updated on every packet transmission/receipt.
now: if_lastchange get updated when IFF_UP is changed.

thorpej ca4d373730 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.

and only splnet() is allowed for the protection of data structures
used by network devices.

thorpej 896cba1b56 if_alloc_sadl(): if the interface already has a link name, free
it before assigning a new one.  This is useful for interfaces
that may change their link names in the course of their existence.

itojun df9784d749 pull post-4.4BSD change to sys/net/route.c from BSD/OS 4.2 (UCB copyrighted).
have sys/net/route.c:rtrequest1(), which takes rt_addrinfo * as the argument.
pass rt_addrinfo all the way down to rtrequest, and ifa->ifa_rtrequest.
3rd arg of ifa->ifa_rtrequest is now rt_addrinfo * instead of sockaddr *
(almost noone is using it anyways).

benefit: the follwoing command now works.  previously we need two route(8)
invocations, "add" then "change".
# route add -inet6 default ::1 -ifp gif0

remove unsafe typecast in rtrequest(), from rtentry * to sockaddr *.  it was
introduced by 4.3BSD-reno and never corrected.

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.
someone with more clue about netiso-over-ip, please help.

thorpej fc5dafc79b Fix a rather annoying problem where the sockaddr_dl which holds
the link level name for the interface (ifp->if_sadl) is allocated
before ifp->if_addrlen is initialized, which could lead to allocating
too little space for the link level address.

Do this by splitting allocation of the link level name out of
if_attach() and into if_alloc_sadl(), which is normally called
by functions like ether_ifattach().  Network interfaces which
don't have a link-specific attach routine must call if_alloc_sadl()
themselves (example: gif).

Link level names are freed by if_free_sadl(), which can be called
from e.g. ether_ifdetach().  Drivers never need call if_free_sadl()
themselves as if_detach() will do it if it is not already done.

While here, add the ability to pass an AF_LINK address to
SIOCSIFADDR in ether_ioctl() (this is what caused me to notice
the problem that the above fixes).

also takes an argument indicating whether or not the interface should
also be disabled (i.e. power removed, resources freed, etc.)

thorpej 8dc841aa19 Change the behavior of ifpromisc() slightly. If interface is not IFF_UP,
attempting to enable promisc would result in ENETDOWN.  Change this to
allow the interface to always be placed in promiscuous mode, regardless
of IFF_UP.  When the interface does come up, the IFF_PROMISC flag will
be consulted, and this matches the behavior that disabling promiscuous
mode has.

thorpej 1e58f22342 Add the notion of "cloning" of network pseudo-interface (e.g. `gif').
This allows them to be created and destroyed on the fly via ifconfig(8),
rather than specifying the count in the kernel configuration file.

thorpej fc96443d15 New callout mechanism with two major improvements over the old
timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
  resource allocation.
- Insertion and removal of callouts is constant time, important as
  this facility is used quite a lot in the kernel.

The old timeout()/untimeout() API has been removed from the kernel.

thorpej 0f5c059d1f - Add link status to if_data, so that routing daemons and other interested
parties can easily know the state of a link.
- Define an interface announcement message for the routing socket so that
  routing daemons and other interested parties know when an interface
  is attached/detached.

thorpej 72ecabeb4d In if_detach(), call PRU_PURGEIF for *every* protocol within a domain
that has a usrreq entry point.  Each protocol may have its own PCB
tables that need to be purged of references to the interface.

thorpej c1185c1020 PRU_PURGEADDR -> PRU_PURGEIF, per a discussion w/ itojun. In the IPv4
and IPv6 code, also use this to traverse PCB tables, looking for cached
routes referencing the dying ifnet, forcing them to be refreshed.

thorpej d844a3ac41 First-draft if_detach() implementation, originally from Bill Studnemund,
although this version has been changed somewhat:
- reference counting on ifaddrs isn't as complete as Bill's original
  work was.  This is hard to get right, and we should attack one
  protocol at a time.
- This doesn't do reference counting or dynamic allocation of ifnets yet.
- This version introduces a new PRU -- PRU_PURGEADDR, which is used to
  purge an ifaddr from a protocol.  The old method Bill used didn't work
  on all protocols, and it only worked on some because it was Very Lucky.

This mostly works ... i.e. works for my USB Ethernet, except for a dangling
ifaddr reference left by the IPv6 code; have not yet tracked this down.

bouyer 075ea2cfea Fix ifa_ifwithnet() for the netatalk case: netatalk uses blocks of addresses
which can't be handled by netmask, and ifa_ifwithnet() didn't find the
interface associated with an adress if it was in the same block but not with
the same prefix. This prevented 'route add' and atalkd to work properly
with some network configs.
This has been discussed on tech-net some weeks ago.

itojun 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.
