* Refactor the initial learning configuration (port learning, address expiry,
handling address moving between ports, etc, etc) into a separate HAL routine
* and ensure that it's consistent between switch chips - the AR8216,8316,724x,9331
SoCs all share the same switch code.
* .. the AR8327 needs doing - the defaults seem OK for now
* .. the AR9340 is different but it's also programmed now.
* Add support for flushing a single port worth of ATU entries
* Add support for fetching the ATU table from AR8216 and derived chips
Tested:
* AR9344, Carambola 2
TODO:
* Further testing on other chips
* Add AR9340 support
* Add AR8327 support
Stop leaking kernel pointers though theses sysctls and make sure that the
padding in the structures is zeroed on allocation to avoid other leaks.

preference to LIBFICL{,32}. LIBFICL{,32} are now always defined, but
LDR_INTERP{,32} is defined empty when building w/o forth (aka the
simple interpreter) and defined to LIBFICL{,32} when we are building
forth.
I had thought that this would be useful. However it was committed too
late, and wound up being unused. It's in the way of future work now,
so retire it rather than bring it forward.
loader scripts. However, that path won't be taken after all it
seems. Remove this code before it decays into uselessness. Also remove
build dependencies on forth no longer needed.
This has never been installed. It was added to the tree disconnected
to the build in FreeBSD 5 (17 years ago) and has never been used as
far as I can tell. The desired improvements never really happened
(despite a couple minor cleanups along the way). It's relevance is
long past, so better to retire it.

Otherwise we might not write out the last chunk that is shorter than

This become important after the r324794.

Fix a pretty simple, yet pretty tragic typo: we should return IPPROTO_DONE,
not IPPROTO_NONE. With IPPROTO_NONE we will keep parsing the header chain
on an mbuf that was already freed.

MK_CTF, MK_SSP, MK_PROFILE, NO_PIC, and INTERNALLIB are always the
same, so set them in defs.mk. MAN= is common, so set it here too.
This removes a lot of boring repetition from the Makefiles that added
almost no value.
This stuff may be a bit fluid during this -HEAD cycle as various other
switch features are added, but the current stuff is enough to drive
initial development and features on the atheros range of integrated
and external switches.
* add a method to flush the whole address table;
* add a method to flush all addresses on a given port;
* add a method to download the address table;
* .. and then a method to fetch entries from the address table.
The table fetch/read methods pass through to the drivers for now since
the drivers may implement different ways of fetching/caching the address
table data. The atheros devices for example fetch the table by
iterating over the table through a set of registers and so you need
to keep that locked whilst you iterate otherwise you may have the table
flushed half way by a port status change.
This is a no-op until the userland and arswitch code shows up.
The old way required the data to be present really early and copied it from
memory mapped NOR flash; this only worked during kernel boot but not for
ath/ath_hal modules.
Tested:
* AR9331, Carambola2, ath/hal modules.
1) The OPW() function macro should have the same return type like the
function it executes.
2) The DEVFS I/O-limit should be enforced for all character device reads
and writes.
3) The character device file handle should be passable, same as for
DEVFS based file handles.

Whether we should be overwriting the loaded FDT module with the 'fixed up'
version or not was questionable when this was added, and now that overlays
are possible this is downright wrong.
Overlays can increase the size of the blob, so writing it back to the
original VA will generally write past the end of the block and start
clobbering other things in memory.
Rip it out- it was questionable to begin with, it's doing bad things now,
and it serves no purpose since the modified blob will be copied into place
rather than relying on this to reflect the changes.

akin to what Pedro Souza and Wojciech Koszek did in the lua GSoC with
interp.h, interp_simple.c and changes to interp.c and interp_forth.c,
but completely redone from scratch.
This effectively restores the spirit of r326712 (my first attempt to
bring in Pedro's and Wojciech's work) updated for new requirements
that had silently broke their original work. This change also differs
by using fixed function names instead of function pointers to simply
things. Only one interpreter at a time may be compiled in.
Also of note: we take a mutable string, pass it in via a const char *
pointer into intrp_forth's interp_run(). We then cast away the const
to pass into ficlExec since ficl would require extensive changes to
properly const-poison. See Sections 6.5.2.5 and 6.7.3 of C11 standard
noting it's only UB if you modify a const object through a non-const
pointer, but not char [] -> const char * -> char * as here.
