06daa0588c Two more fixes to if_detach. These are generic to all interfaces and
do not pollute the interface further.

o Run if_detach at splnet().
o Creatively swipe the relevant parts of the netatm atm_nif_detach
  which will delete the relevant references to the interface going
  away.

ce079123e3 The current code incorrectly assumes that all vlans
are configured, and/or associated with a parent device.  If you
receive a frame for a VLAN that's not in the list, you walk off

108333f0a4 Add some gross ad-hock hacks to increase stability of if_detach:
o be more careful about clearing addresses (this isn't a kludge)
o For AF_INET interfaces, call SIOCDIFFADDR to remove last(?) bit
  of cruft.

Special cases for AF_INET shouldn't be here, but I didn't see a good
generic way of doing this.  If I missed something, please let me know.

This gross hack makes pccard ejection stable for ethernet cards.

6a226314fd Fix a route table leak in rtalloc() and rtalloc_ign(). It is
possible for ro->ro_rt to be non-NULL even though the RTF_UP flag
is cleared.  (Example: a routing daemon or the "route" command
deletes a cloned route in active use by a TCP connection.)  In that
case, the code was clobbering a reference to the routing table
entry without decrementing the entry's reference count.

The splnet() call probably isn't needed, but I haven't been able
to prove that yet.  It isn't significant from a performance standpoint
since it is executed very rarely.

81fceb37a9 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.

e060599533 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.

a2c68c62db 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

d612df1de6 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.
