5596676e6c KSE Milestone 2
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.

Sorry john! (your next MFC will be a doosie!)

829347d510 Implement direct support for semipersistant nodes.
(e.g. ethernet nodes are persistent until you rip out the hardware)
Use this support in the ethernet and sample nodes.
Add some more abstraction on the 'item's so that  node and
hook reference counting can be checked easier.
Slight man page correction.
Make pppoe type dependent on ethernet type.
Clean up node shutdown a little.
Move a mutex from MTX_SPIN to MTX_DEF (oops)
Fix small ref-counting bug.
remove warning on one2many type.

95d27233f3 Add a generic "queued function callin" mechanism
Use it to implement (hopefully) SMP safe node/hook addition
and removal.
Fix some debug stuff.

ff86256bf7 Part 2 of the netgraph rewrite.
This is mostly cosmetic changes, (though I caught a bug or two while
makeing them)

f0c46a9d00 Rewrite of netgraph to start getting ready for SMP.
This version is functional and is aproaching solid..
notice I said APROACHING. There are many node types I cannot test
I have tested: echo hole ppp socket vjc iface tee bpf async tty
The rest compile and "Look" right.  More changes to follow.
DEBUGGING is enabled in this code to help if people have problems.

0c949560a1 Divorce the kernel binary ABI version number from the message
format version number. (userland programs should not need to be
recompiled when the netgraph kernel internal ABI is changed.

Also fix modules that don;t handle the fact that a caller may not supply
a return message pointer. (benign at the moment because the calling code
checks, but that will change)

This clears out my outstanding netgraph changes.
There is a netgraph change of design in the offing and this is to some
extent a superset of soem of the new functionality and some of the old
functionality that may be removed.

This code works as before, but allows some new features that I want to
work with and evaluate. It is the basis for a version of netgraph
with integral locking for SMP use.

This is running on my test machine with no new problems :-)

db0edd3c39 Fix a bug where if the interface was in promiscuous mode when the
last hook was disconnected, the interface would not get reset to
non-promiscuous mode.

0a22d74ab0 When sending a packet back to a network interface to simulate an arrived
packet, make sure that the packet has the interface marked in the first mbuf,
the same a truely arrived packets would have.

d826d6c208 Add three more control messages to complement their opposites:
NGM_ETHER_SET_ENADDR, NGM_ETHER_GET_PROMISC, and NGM_ETHER_GET_AUTOSRC.
Alter parsing algorithm so the EN address really looks like one.

32c8825fe1 Remove node's name reference when the interface is detached;
otherwise, the ng_ether.ko KLD will never be unloadable after
all Ethernet interfaces are detached, as it should be, because
of the lingering extra reference.

8c0bd98e14 Don't forget to set our MAC address into packets we wre sending out via
netgraph. Eventually we may need to have a separate hook for packets
that already have a source AMC address but for now just drop it in.
Should fix PPPoE.

9af816e946 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.
