f95f4dac4c Add two new generic control messages, NGM_ASCII2BINARY and
NGM_BINARY2ASCII, which convert control messages to ASCII and back.
This allows control messages to be sent and received in ASCII form
using ngctl(8), which makes ngctl a lot more useful.

This also allows all the type-specific debugging code in libnetgraph
to go away -- instead, we just ask the node itself to do the ASCII
translation for us.

Currently, all generic control messages are supported, as well as
messages associated with the following node types: async, cisco,
ksocket, and ppp.

See /usr/share/examples/netgraph/ngctl for an example of using this.

Also give ngctl(8) the ability to print out incoming data and
control messages at any time.  Eventually nghook(8) may be subsumed.

Several other misc. bug fixes.

d49b10a83a Expand the field width for subtypes. We had already overflowed it
by 2 with people just adding numbers on the end of the ethernet subtypes.
We now have an additional 14 subtypes available in ethernet.
Use one of them immediatly for homePNA.

23ccdea8bb Only emit the ``wrong ifa'' message if the matching interface
is neither IFF_LOOPBACK or IFF_POINTOPOINT.  It's quite common
(and probably more correct) to route local IP numbers via lo0
and it makes configuration easier to assign the hostname address
to local POINTOPOINT links too.

This message usually remains hidden because the loopback interface
gets the highest interface number at boot time, but when the
ethernet interface is added later, the message can get pretty
annoying.

Also, fix a typo.

the packet already has a valid link-level source address.  This defaults
to off (the address is overwritten)

a175011ce8 This patch clears the way for removing a number of tty related
fields in struct cdevsw:

        d_stop          moved to struct tty.
        d_reset         already unused.
        d_devtotty      linkage now provided by dev_t->si_tty.

These fields will be removed from struct cdevsw together with
d_params and d_maxio Real Soon Now.

The changes in this patch consist of:

        initialize dev->si_tty in *_open()
        initialize tty->t_stop
        remove devtotty functions
        rename ttpoll to ttypoll

024e9c590a Remove NBPF conditionality of bpf calls in most of our network drivers.
This means that we will not have to have a bpf and a non-bpf version
of our driver modules.

This does not open any security hole, because the bpf core isn't loadable

The drivers left unchanged are the "cross platform" drivers where the respective
maintainers are urged to DTRT, whatever that may be.

Add a couple of missing FreeBSD tags.

adcee7f9a2 Increase the size of the route reference count from 15 bits to 31 bits.
This doesn't change the size or alignment of the structure on either i386
or Alpha, and thus should be binary-compatible (modulo problems with old
applications and routes with more than 2^15 references).

6975958ce7 Never return the root node itself from rn_match(); return NULL instead.
This caused a panic in rtfreee() called with a root node from the
routing socket code (when processing a RTM_GET message looking for
the default route while there is none).

Since no existing code seems to have any use getting the root node
from rn_match(), it seems cleaner never to return it rather than
check for this condition at the caller's.

591a564670 Add a new interface ioctl, to return "aux status".
This is inteded for to allow ifconfig to print various unstructured
information from an interface.

The data is returned from the kernel in ASCII form, see the comment in
if.h for some technicalities.

Canonical cut&paste example to be found in if_tun.c

Initial use:
        Now tun* interfaces tell the PID of the process which opened them.

Future uses could be (volounteers welcome!):
        Have ppp/slip interfaces tell which tty they use.
        Make sync interfaces return their media state: red/yellow/blue
        alarm, timeslot assignment and so on.

bb0e3278df Introduce IFF_SMART bit.
This means that the driver will add/delete routes when it knows it is
up/down, rather than have the generic code belive it is up if configured.

This is probably most useful for serial lines, although many PHY chips
could probably tell us if we're connected to the cable/hub as well.

447bf5968f Simplify cdevsw registration.
The cdevsw_add() function now finds the major number(s) in the
struct cdevsw passed to it.  cdevsw_add_generic() is no longer
needed, cdevsw_add() does the same thing.

cdevsw_add() will print an message if the d_maj field looks bogus.

Remove nblkdev and nchrdev variables.  Most places they were used
bogusly.  Instead check a dev_t for validity by seeing if devsw()
or bdevsw() returns NULL.

Move bdevsw() and devsw() functions to kern/kern_conf.c

Bump __FreeBSD_version to 400006

This commit removes:
        72 bogus makedev() calls
        26 bogus SYSINIT functions

if_xe.c bogusly accessed cdevsw[], author/maintainer please fix.

I4b and vinum not changed.  Patches emailed to authors.  LINT
probably broken until they catch up.
