Renumber cluase 4 to 3, per what everybody else did when BSD granted
them permission to remove clause 3. My insistance on keeping the same
numbering for legal reasons is too pedantic, so give up on that point.

* flesh out a "get default DFS parameters" routine
* remove the stub that returns NULL
* fix up the enable DFS method to do what FreeBSD does - specifically, allow pe_enabled
to be set/cleared.
This allows the radar pulse reporting code to function, but it doesn't yet
do anything useful.
* add debugging
* disable the manual noise floor calibration and tracking done by the HAL;
this interferes with the normal calibration path and will lock up the RX
side
* don't program short report / priority if they're provided as NOVAL.
All devices:
- add support for rate adaptation via ieee80211_amrr(9);
- use short preamble for transmitted frames when needed;
- multi-bss support:
* for RTL8821AU: 2 VAPs at the same time;
* other: 1 any VAP + 1 sta VAP.
RTL8188CE:
- fix IQ calibration bug (reason of significant speed degradation);
- add h/w crypto acceleration support.
USB:
- A-MPDU Tx support;
- short GI support;
Other:
- add support for RTL8812AU / RTL8821AU chipsets
(a/b/g/n only; no ac yet);
- split merged code into subparts:
* bus glue (usb/*, pci/*, rtl*/usb/*, rtl*/pci/*)
* common (if_rtwn*)
* chip-specific (rtl*/*)
- various other bugfixes.
Due to code reorganization, module names / requirements were changed too:
urtwn urtwnfw -> rtwn rtwn_usb rtwnfw
rtwn rtwnfw -> rtwn rtwn_pci rtwnfw
Tested with RTL8188CE, RTL8188CUS, RTL8188EU and RTL8821AU.

* add support to read the timer and capability
* add support to enable/disable the location timer.
On AR9380 at least, enabling the location timer is required to make
the timer tick, otherwise location packets return a timestamp of 0.
However, it then makes /all/ RX packets use the RX location timestamp
instead of the TSF timestamp.
So, unless I find another magical way to do location timestamping,
we will have to dynamically switch things on/off and ensure the
TX/RX path handles the "different" timestamps correctly.
Tested:
* AR9380, STA mode
* LOC_INFO is mostly just "did this packet come with a locationing
timestamp instead of TSF";
* Decode not-sounding, uploaded-data, data-valid, data type and
number of extension spatial streams.
* If fast_ts is set then the TX timestamp is the fast timestamp, not
normal TSF.
* If the TX descriptor has the position bit set then request locationing
and clear sounding-disable. This way we (a) get the response with
the TX timestamp from the location side of things, and (b) we get
a CSI dump of the response ACK, which we will eventually use in the
locationing path.
* the code already stored the length of the RX desc, which I never used.
So, use that and retire the new flag I introduced a while ago.
* Introduce a TX timestamp length field and capability.
Among other things, this introduces the idea of DBA-gated queues that
aren't the CABQ. The TDMA support requires this.
Tested:
* AR9580 (hostap mode)
* AR9380 (sta mode)
Approved by: re (gjb)
This is in preparation for some other TDMA fixes which will hopefully
end with having working TDMA.
But, it does avoid lots of read/modify/writes in the txq setup path.
* Allow readyTime to just be programmed in directly
* The beacon interval and all of the beacon timing sysctl's are in TU,
not TSF. So, we were doing the wrong math on the CAB programming
in the first place.
This seems to make 5G work better.
It doesn't fix powersave handling though, that still sees the PHY get
stuck during initial calibration and everything goes pear shaped.
I'll look into that later.
Tested:
* QCAFN222 NIC, STA mode, 5GHz
Obtained from: Linux ath9k
Turns out I wasn't even initialising or programming a lot of stuff
for the AR9462 2.1 chip. Oops.
This mostly gets it working. powersave scan results in some pretty
hilarious NFcal hangs and I don't see beacons reliably.
There are still some xlna gain tables missing that ath9k has; I'll
follow up with some fixes and then see if the QCAFN222 NIC I have
tests this path.
Tested:
* QCAFN222 NIC, STA mode, 2GHz and 5GHz
These are apparently conditional on there being a shared PA/LNA, which
at least on AR9462/QCA9535 devices I have isn't a thing.
I'm .. not yet sure which devices it /is/ a thing, so I'll come back
to that.
Tested:
* QCA9565 STA + bluetooth
Obtained from: Linux ath9k
* Add extra debugging - the weights debugging is really useful to ensure
things are programmed into the wlan coexistence table. The weights are
what traffic priority each of the various modes get (tx, tx-high-priority,
rx-beacon, etc) if they're all zero, things work very poorly.
* Add in coex init routines from ath9k for AR9462 and QCA9565 1ANT and 2ANT.
This control things like beacon stomping, ACK handling, antennas, PA/LNA
shared, etc.
* Some ancillary bits.
TODO:
* There's some conditional stuff around MCI_ANT_ARCH_PA_LNA_SHARED() in ath9k
which doesn't always enable force-on LNA. That'll have to be examined
and merged in as appropriate.
Obtained from: linux ath9k
Notably, this also sets AR_BTCOEX_WL_LNADIV to FORCE_ON, so LNA diversity
is always enabled and under control of the wifi chip.
Tested:
* QCA9565, STA + bluetooth mode
Obtained from: Linux ath9k
This configures the LNA antenna diversity control, which should be on
if wlan owns the LNA for bluetooth coexistence. Otherwise, make sure
it's off.
I think this is eventually intended to allow 1-antenna bluetooth +
wifi setups for QCA9565, but I'm not sure where that's actually configured
in ath9k.
