0384fff8c5 Major update to the way synchronization is done in the kernel. Highlights
include:

* Mutual exclusion is used instead of spl*().  See mutex(9).  (Note: The
  alpha port is still in transition and currently uses both.)

* Per-CPU idle processes.

* Interrupts are run in their own separate kernel threads and can be
  preempted (i386 only).

71582bf515 o Add missing "\n" to warning output in netinet/if_loop.c, when an
unsupported address family is used on localhost interface.

    looutput: af=0 unexpected

  Speculation as to the reasons for my seeing this error are welcome, of
  course.  :-)

db90128160 Avoid the modules madness I inadvertently introduced by making the
cloning infrastructure standard in kern_conf.  Modules are now
the same with or without devfs support.

If you need to detect if devfs is present, in modules or elsewhere,
check the integer variable "devfs_present".

This happily removes an ugly hack from kern/vfs_conf.c.

This forces a rename of the eventhandler and the standard clone
helper function.

Include <sys/eventhandler.h> in <sys/conf.h>: it's a helper #include
like <sys/queue.h>

Remove all #includes of opt_devfs.h they no longer matter.

3f54a085a6 Remove all traces of Julians DEVFS (incl from kern/subr_diskslice.c)
Remove old DEVFS support fields from dev_t.

  Make uid, gid & mode members of dev_t and set them in make_dev().

  Use correct uid, gid & mode in make_dev in disk minilayer.

  Add support for registering alias names for a dev_t using the
  new function make_dev_alias().  These will show up as symlinks
  in DEVFS.

  Use makedev() rather than make_dev() for MFSs magic devices to prevent
  DEVFS from noticing this abuse.

  Add a field for DEVFS inode number in dev_t.

  Add new DEVFS in fs/devfs.

  Add devfs cloning to:
        disk minilayer (ie: ad(4), sd(4), cd(4) etc etc)
        md(4), tun(4), bpf(4), fd(4)

  If DEVFS add -d flag to /sbin/inits args to make it mount devfs.

  Add commented out DEVFS to GENERIC

a66233226c Fix if_types.h as per the IANA assignments with regard to IPv6.
gif/faith/stf moved to 0xfN entries, since their previous location
is allocated to some other interfaces.
Also add the IFT_PVC, which is the ATM PVC subinterface from ALTQ.

This also syncs us up a bit to NetBSD again.

This change requires a total recompilation of all kmem users, as
itojun told me.

Next in line is synching to the IANI SMI list.

a5213f145a Add the tap driver.
The tap driver is used to present a virtual Ethernet interface to the
system. Packets presented by the network stack to the interface are
made available to a character device in /dev. With tap and the bridge
code, you can make remote bridge configurations where both sides of
the bridge are separated by userland daemons.

This driver also has a special naming hack to allow it to serve a similar
purpose to the vmware port.

e1e1452d61 Make the ng_ether(4) node type dynamically loadable like the rest.
This means 'options NETGRAPH' is no longer necessary in order to get
netgraph-enabled Ethernet interfaces. This supports loading/unloading
the ng_ether.ko and attaching/detaching the Ethernet interface in any
order.

Add two new hooks 'upper' and 'lower' to allow access to the protocol
demux engine and the raw device, respectively. This enables bridging
to be defined as a netgraph node, if so desired.

b106252c19 Implement SIOCSIFLLADDR, which allows you to change the link-level
address on an interface. This basically allows you to do what my
little setmac module/utility does via ifconfig. This involves the
following changes:

socket.h: define SIOCSIFLLADDR
if.c: add support for SIOCSIFLLADDR, which resets the values in
      the arpcom struct and sockaddr_dl for the specified interface.
      Note that if the interface is already up, we need to down/up
      it in order to program the underlying hardware's receive filter.
ifconfig.c: add lladdr command
ifconfig.8: document lladdr command

You can now force the MAC address on any ethernet interface to be
whatever you want. (The change is not sticky across reboots of course:
we don't actually reprogram the EEPROM or anything.) Actually, you
can reprogram the MAC address on other kinds of interfaces too; this
shouldn't be ethernet-specific (though at the moment it's limited to
6 bytes of address data).

Nobody ran up to me and said "this is the politically correct way to
do this!" so I don't want to hear any complaints from people who think
I could have done it more elegantly. Consider yourselves lucky I didn't
do it by having ifconfig tread all over /dev/kmem.

fe81f64ffc Rather than checking for hlen causing misalignment, we should do the
m_adj() and then check the resulting mbuf for misalignment, copying
backwards to align the mbuf if required.

This fixes a longstanding problem where an mbuf which would have been
properly aligned after an m_adj() was being misaligned and causing an
unaligned access trap in ip_input().  This bug only triggered when booting
diskless.

2e2de7f23f Move code to handle BPF and bridging for incoming Ethernet packets out
of the individual drivers and into the common routine ether_input().
Also, remove the (incomplete) hack for matching ethernet headers
in the ip_fw code.

The good news: net result of 1016 lines removed, and this should make
bridging now work with *all* Ethernet drivers.

The bad news: it's nearly impossible to test every driver, especially
for bridging, and I was unable to get much testing help on the mailing
lists.
