28070a0efe Bring in latest CSRG revisions to this file: 
- Report destination address of a P2P link when servicing
  routing socket messages.

- Report interface name, address, and destination address
  of a P2P link when servicing NET_RT_{DUMP,FLAGS} sysctls.

Part of CSRG revision 8.6 coresponds to revision 1.12.
CSRG revision 8.7 corresponds to revision 1.15.

05153c617d if_index is the highest interface index in the system, not the next 
available index.

b9d45cebf4 The interface index space may be sparsely populated (e.g. when an 
interface in the middle is if_detach()'d).  Return (and handle)
 ENOENT when the ifmib(4) is accessed for a nonexistent interface.

211f625a91 Set the interface speed back to zero, after ether_ifattach() set it 
to 10Mbps.  RFC 2863 says: "For a sub-layer which has no concept
of bandwidth, [ifSpeed] should be zero."

ffb5a10458 Move device nodes into a /dev/net/ directory, to avoid conflict with 
existing devices (e.g.: tunX).  This may need a little more thought.

Create a /dev/netX alias for devices.  net0 is reserved.

Allow wiring of net aliases in /boot/device.hints of the form:
	hint.net.1.dev="lo0"
	hint.net.12.ether="00:a0:c9:c9:9d:63"

242c766b79 - Fix typo in "didn't find tag in list" code -- != should have been ==. 
This fixes the panic when receiving a packet with an unknown tag, and
  also allows reception of packets with known tags.
- Allow overlapping tag number spaces when using multiple hardware-assisted
  VLAN parent devices (by comparing the parent interface in
  vlan_input_tag() just as in vlan_input() ).
- fix typo in comment

830cc17841 Two main changes here: 
+ implement "limit" rules, which permit to limit the number of sessions
   between certain host pairs (according to masks). These are a special
   type of stateful rules, which might be of interest in some cases.
   See the ipfw manpage for details.

 + merge the list pointers and ipfw rule descriptors in the kernel, so
   the code is smaller, faster and more readable. This patch basically
   consists in replacing "foo->rule->bar" with "rule->bar" all over
   the place.
   I have been willing to do this for ages!

abb6470625 Make stf a clonable device. 
Yes this really is rather silly and the implementation is overkill given
that you are only allowed one of them, but NetBSD implements cloning on
this device and it's a less cluttered example of cloning then most.

Note ALL MODULES MUST BE RECOMPILED
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.
