Migrate athregs over to use the new stats API.

Migrate athstats to use the new stats API.

Begin abstracting out the access method for ath(4) ioctls.

Each of the ath* commands do their own direct socket/ioctl calls,
which makes it difficult to forklift upgrade things.

So, this is the beginning of abstracting out the stats API calls
in the hope that I can migrate things to use a /dev/athX file for
ioctls and use a more general interface.

Tested:

* QCA9565 NIC, STA mode

DIRDEPS_BUILD: Regenerate without local dependencies.

These are no longer needed after the recent 'beforebuild: depend' changes
and hooking DIRDEPS_BUILD into a subset of FAST_DEPEND which supports
skipping 'make depend'.

Add a format string to the err() calls.

Remove the hard-coded 'ath0' strings and use ATH_DEFAULT.

Remove the duplicate ATH_DEFAULT fields. The build bits should be including
../Makefile.inc as appropriate.

Add META_MODE support.

Off by default, build behaves normally.
WITH_META_MODE we get auto objdir creation, the ability to
start build from anywhere in the tree.

Still need to add real targets under targets/ to build packages.

Make these all work with the new way of doing privatelib.

Without these CFLAGS settings a cross-compile won't find the headers
anywhere.

Tested:

* mips (32, big endian) cross-build w/ LOCAL_DIRS including these
tools.

Stop including if_var.h from userland.

Typecast things.

Don't use a private copy of the ANI definitions - use the HAL definitions.

Whilst I'm at it:

* fix the NI+ to be correct, rather than NI-;
* use the diag api codes, now that the HAL is public.

Tested:

* AR9380, STA mode

Bump mask to be 64 bits - this fixes seeing MCS rates > 19.

Tested:

* AR9380, STA mode, associated to a 3x3 AP (also FreeBSD)

Convert to LIBADD

Add in decode for the AR9300 RX descriptor.

Update these to make them actually compile!

Tested:

* cross compilation to MIPS

Allow it to compile again.

Make the libbsdstat useful again.

Fix paths.

Add more tools to the build.

Update athpoke/athregs to use the modified register read diagnostic API.

Fix athdecode to actually work.

* Add AR9287 and AR9331 chipset support - it just uses the AR5416 support
for now so some of the register mappings are wrong, but it works well
enough.

* don't call exit() from opmark().

Eliminate last vestigies of NO_MAN= in the tree. Also, remove
ineffectual NOMAN= lines. These don't change the build at all.

NO_MAN= has been deprecated in favor of MAN= for some time, go ahead
and finish the job. ncurses is now the only Makefile in the tree that
uses it since it wasn't a simple mechanical change, and will be
addressed in a future commit.

Migrate athstats to use bsdstat.

Fix a compiler warning.

Thanks Clang!

Migrate athaggrstats to use bsdstat.

To avoid having to explicitly test COMPILER_TYPE for setting
clang-specific or gcc-specific flags, introduce the following new
variables for use in Makefiles:

CFLAGS.clang
CFLAGS.gcc
CXXFLAGS.clang
CXXFLAGS.gcc

In bsd.sys.mk, these get appended to the regular CFLAGS or CXXFLAGS for
the right compiler.

Add AR9300 descriptor decoding.

Print out the RTS/CTS rate in the TX descriptor.

Fix incorrect format string.

Add a very skeletal spectral scan control application.

The main use for this is to manually trigger spectral scan operations
(athspectral -i athX start) whilst doing debugging.

Add in a totally hacked up copy of the AR5416 descriptor decoding stuff,
as well as TDMA related things.

I used this to debug TDMA related issues in -HEAD.

Make this a flag.

Implement AR5210 descriptor decoding.

Add AR5211 descriptor decoding support.

Add AR5212 frame decoding support.

Implement a basic data decoder for the data produced by if_ath_alq.

This decodes the AR5416 family 11n TX and RX descriptors.

Add some colour to make it easy (well, easier) to see what the current
selected rates and current sample rates are.

(Note: when run under high traffic and with -s 0.1 the display becomes very
mesmerising. You've been warned.)

Add a '-s <timeout>' option which will display live rate control
statistics.

Tidy up the output quite substantially, making it fit well within
80 columns.

This makes it much easier to use in a shell script, to display a "top"
style output with live rate control data.

Make this build again!

Minor mdoc fix.

Add a missing HAL_DMA_ADDR definition.

Add HAL_DMA_ADDR.

Break out the parsing code from main() and modularise things a little.

The eventual aim will be to support listing "one" and "all" stations for
the given ath device.

Add a needed #include due to my recent change.

Add missing SRCS.

Add the new athratestats tool.

Tidy things up substantially:

* remove some debugging;
* introduce command line arguments;
* introduce support for non-ath0 interfaces.

Use the rate control table to display the rate rather than the rix,
making the output of this program much more meaningful.

Implement a first cut of the 'sample' rate statistics userland utility.

This outputs almost exactly the same information as the kernel sysctl does,
however the rix -> rate mapping isn't yet available as a TLV.

Bump this up - that way the AR9300 and later MACs get covered (for now)
by the AR5416 register map.

Convert athdebug to use the 64 bit dev.ath.X.debug sysctl.

Add athaggrstats to the ath(4) tools build.

Flesh out 'athaggrstats', a utility which will display the aggregation
specific statistics for ath(4).

Change cc -> bc : "bc" is "busy count", which is the % of time the channel
is considered "busy but not doing any active TX or frame RX."

Just keep in mind that "frame RX" is "decoding what looks like a wifi
signal", not necessarily "frame successfully decoded for this particular
device."

Add a tool to print out min, average and max channel survey information
from the current channel.

There seem to be some occasional issues with the extension channel
counters reporting more than 100% of use. I'll investigate that
soon.

Add AR_ISR_S5 and AR_ISR_S5_S.

Add a threadid to the ah_decode API.

This adds the current thread ID to each logged register and mark entry,
allowing for easier debugging of concurrent/overlapping NIC operations.

Stop some of the output from wrapping at 80 characters.

Fix up this local copy of statfoo to support > 128 statistics.

This allows all of the athstats statistics to work again.

Specifics:

* The previous code used chars < 0x80 as printable, and chars >= 0x80
as "statistics"
* .. which meant any statistic above 127 would wrap around to 0;
* .. so once I added the 802.11n TX/RX statistics to athstats, the tail
end of the statistics list weren't accessible.

This patch:

* adds a define which represents the magic character, rather than a hard
coded one
* the statistic in question is little endian encoded after the magic
character.

Notes:

* statfoo is useful enough to possibly warrant turning into a library API.

Add some missing radar config parameters.

Oops, my bad. Fix a broken thing I introduced earlier.

Include an EEPROM dump program for the AR9287 EEPROM format.

This is a full 32 bit field for kite.

Generate opt_ah.h now for all ath tools, a recent HAL change of mine
now requires it.

* re-enable marker stuff, I accidentally disabled it during debugging
* correct arg check

Flesh out a simple tool to print the ALQ dump generated by the HAL.

Oops, fix badness i must've introduced earlier.

The regdomain entries are 16 bits, not 8. Print out all 16 bits.

Update to keep in sync with the HAL

Add support for printing out the open-loop TX power control EEPROM fields.

* add in new EEPROM fields from later revisions
* add in printing futureBase

Keep this in sync with the ar5212 power rate table size.
This doesn't yet know about the 802.11n radios or rates.

Fix this tool to use the updated (corrected) v4k eeprom definition introduced in a previous commit.

Add a simple tool to print the contents of a v4k EEPROM dump.

Add a new tool which takes a text hexdump of the current EEPROM contents.

Patch the athstats code/Makefile to cross-compile correctly.

Add in a new tool which prints a formatted v14 eeprom from an eeprom
hexdump.

This is a part replacement of the old athprom code, which tries
to both fetch and print the contents of an eeprom dump.

A tool to generate hexdumps from a running system will follow shortly.

Remove an un-needed trailing / after OBJDIR.

Nitpicked by: juli

Make the existing ath tools build again.

* add missing includes to quieten warnings
* fix an inline function decl to have a return type
* since .h files are created during the build (opt_ah.h, ah_osdep.h)
which modify the behaviour of the HAL include/source files,
include OBJDIR in the path so the #include's work.

The tools should now build when the directory is added to LOCAL_DIRS
during a make buildworld.

TDMA support for long distance point-to-point links using ath devices:
o add net80211 support for a tdma vap that is built on top of the
existing adhoc-demo support
o add tdma scheduling of frame transmission to the ath driver; it's
conceivable other devices might be capable of this too in which case
they can make use of the 802.11 protocol additions etc.
o add minor bits to user tools that need to know: ifconfig to setup and
configure, new statistics in athstats, and new debug mask bits

While the architecture can support >2 slots in a TDMA BSS the current
design is intended (and tested) for only 2 slots.
