make the kernel aware that there are smaller units of scheduling than the
process. (but only allow one thread per process at this time).
This is functionally equivalent to teh previousl -current except
that there is a thread associated with each process.

particularly nice that IPSEC inserts a zero-length mbuf into the
chain, and that bug should be fixed too, but interfaces should be
robust to bad input.
Print the interface name when TUNDEBUG()ing about dropping an mbuf.
This is to be friendly with non-IPv6 peer (If the peer complains due to
lack of IPv6CP, drop IPv6CP). This basically implements "RXJ+" state
transition in the RFC.

effect, which would cause unnecessary route deletion:
* Unfortunately, this has the obnoxious
* property of also triggering for insertion /above/ a pre-existing network
* route and clones. Sigh. This may be fixed some day.
The effect has been even worse, because recent versions of route.c set
the parent rtentry for cloned routes from an interface-direct route.
For example, suppose that we have an interface "ne0" that has an IPv4
subnet "10.0.0.0/24". Then we may have a cloned route like 10.0.0.1
on the interface, whose parent route is 10.0.0.0/24 (to the interface
ne0). Now, when we add the default route (i.e. 0.0.0.0/0),
rt_fixchange() will remove the cloned route 10.0.0.1. The (bad) effect
also prevents rt_setgate from configuring rt_gwroute, which would not
be an intended behavior.
As suggested in the comments to rt_fixchange(), we need stricter check
in the function, to prevent unintentional route deletion.
This fix also solve the "IPV6 panic?" problem in nd6_timer().

of tunclose() rather than the end, and tunopen() grabbed that unit
before tunclose() finished (one process is allocating it while another
is freeing it!).
It may be worth hanging some sort of rw mutex around all specinfo
calls where d_close and the detach handler get a write lock and all
other functions get a read lock. This would guarantee certain levels
of ``atomicity'' (is that a word?) that people may expect (I believe
Solaris does something like this).

Second, set the IFF_RUNNING flag on an interface after its

Only tun0 -> tun32767 may now be opened as struct ifnet's if_unit
is a short.
It's now possible to open /dev/tun and get a handle back for an available
tun device (use devname to find out what you got).
The implementation uses rman by popular demand (and against my judgement)
to track opened devices and uses the new dev_depends() to ensure that
all make_dev()d devices go away before the module is unloaded.
