as belonging to SPX. This replaces the implicit assumption that the cb
pointer for non-SPX pcb's will be NULL. This isn't required in TCP/IP
as different pcb lists are maintained for different IP protocols; IPX
stores all pcbs on the same global ipxpcb_list.

- Introduce invariant that all IPX/SPX sockets will have valid so_pcb
pointers to ipxpcb structures, and that for SPX, the control block
pointer will always be valid. Don't attempt to free the socket or
pcb at various odd points, such as disconnect.
- Add a new ipxpcb flag, IPXP_DROPPED, which will be set in place of
freeing PCB's so that this invariant can be maintained. This flag
is now checked instead of a NULL check in various socket protocol
calls.
- Introduce many assertions that this invariant holds.
- Various pieces of code, such as the SPX timer code, no longer needs
to jump through hoops in case it frees a PCB while running.
- Break out ipx_pcbfree() from ipx_pcbdetach(). Likewise
spx_pcbdetach().
- Comment on some SMP-related limitations to the SPX code.
- Update copyrights.

variable on the spx_input() stack. It's not very large, and this will
avoid parallelism issues when spx_input() runs in more than one thread at
a time.

IPX PCB lists. Add macros to initialize, destroy, lock, unlock,
and assert the mutex. Initialize the mutex when IPX is started.
Add per-IPX PCB mutexes, ipxp_mtx in struct ipxpcb, to protect
per-PCB IPX/SPX state. Add macros to initialize, destroy, lock,
unlock, and assert the mutex. Initialize the mutex when a new
PCB is allocated; destroy it when the PCB is free'd.

- ipx_pcbnotify(), which is never called.
- ipx_rtchange(), which is never called, is incomplete inplemented, and
also #ifdef notdef.
- spx_fixmtu(), which is never called, is incompletely implemented, and

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!)

BSD's who made this change quite some time ago. More commits to come.
socket addresses in mbufs. (Socket buffers are the one exception.) A number
of kernel APIs needed to get fixed in order to make this happen. Also,
fix three protocol families which kept PCBs in mbufs to not malloc them
instead. Delete some old compatibility cruft while we're at it, and add
some new routines in the in_cksum family.
Use the MAC address of an interface for the host part of an IPX address
and not the MAC address of the first interface for every IPX address.
This is more inline with the way others like Novell do it.

Take out the error messages (the ip icmp equivalent) with #ifdef IPXERRORMSGS.
This is bogus and as far as I could figure out IPX don't have anything like
it. This is a leftover from its XNS heritage. If nobody complains, I will
take it out completely in a few weeks.
Add some more ipxstat statistics counters.
Make ipxprintfs a sysctl variable and off by default.
Add IPX Netbios "routing" support. This is off by default and can be
switched on with a sysctl knob.
General code cleanup to at least use the same style throughout the IPX
code, but also be more style(9) conformant. Also make a lot of functions
static.
If I don't get any complaints I'll bring all of this over to the 2.2 tree
in a few weeks.
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
- don't #include other headers just to get struct names.
- don't use __BEGIN_DECLS/__END_DECLS for system prototypes. It is for
user prototypes.
- don't use extern.
- don't use lines longer than 80 columns.
- use alphabetical order.
- use tabs.

This is a bulk mport of Mike's IPX/SPX protocol stacks and all the
related gunf that goes with it..
it is not guaranteed to work 100% correctly at this time
but as we had several people trying to work on it
I figured it would be better to get it checked in so
they could all get teh same thing to work on..
Mikes been using it for a year or so
but on 2.0
more changes and stuff will be merged in from other developers now that this is in.
