This is getting more common in tablets and laptops. It replaces PS/2 for
the internal keyboard and pointing devices. This is simpler and cheaper
than using up USB ports, and also simpler than the old and quirky PS/2
protocol.
The HID spec is the same no matter what transport is used (it is also
applicable for Bluetooth). Ideally we could create a separate HID bus
manager that would handle all these devices in a generic way, but that
is a lot of work nad extra complications for uncertain gains.
For now, just move the common files to a shared directory where both
drivers can use them. As a result the files are compiled twice, which is
what we want, because currently they hardcode some device paths that
need to be different for each driver.

the API used to set the value from userland via the diagnostic API.

These will only come from userland and it will go and program the rest of
the ANI control parameters with the values in the ANI table.
* Ensure all of the ANI parameters can be tweaked at runtime, even if they're
disabled.

Fix return value check to not complain.
Compilers complain more about things, so let's keep them happy.
Extend the start PCU receive to handle resetting ANI.
One of the fun issues with scanning has been how the existing
ANI values were programmed into the hardware when channels were
changed. If you're on a really crappy channel and ANI has made
you deaf then when you scan you continue to be deaf on all channels.
This code passes in a flag to startpcureceive which in AR5416 and later
is also used to enable ANI. This allows it to know if it's a normal
operation or a scan operation.
This fixes my situation at home where a temporary spot of a device
going deaf due to interference starts scanning and .. can't hear
anything until I restart.
Now, this isn't the full fix - ideally:
(a) all the ANI config and per-channel information would be migrated
to the shared HAL stuff and enabled for all of the NICs;
(b) when a station reassociates and some other error conditions
(like missed beacons, NF calibration failures, etc) a knob
to reset ANI parameters would likely help recovery.
But hey, I'm committing bits of code again! woo!
Tested:
* AR9344 (2G), STA operation
Fix ANI calibration during non-ACTIVE states; start poking at rate control
These are some fun issues I've found with my upstairs wifi link at such a ridiculous
low signal level (like, < 5dB.)
* Add per-station tx/rx rssi statistics, in potential preparation to use that
in the RX rate control.
* Call the rate control on each received frame to let it potentially use
it as a hint for what rates to potentially use. It's a no-op right now.
* Do ANI calibration during scan as well. The ath_newstate() call was disabling the
ANI timer and only re-enabling it during transitions to _RUN. This has the
unfortunate side-effect that if ANI deafened the NIC because of interference
and it disassociated, it wouldn't be reset and the scan would never hear beacons.
The ANI configuration is stored at least globally on some HALs and per-channel
on others. Because of this a NIC reset wouldn't help; the ANI parameters would
simply be programmed back in.
Now, I have a feeling I also need to do this during AUTH/ASSOC too and maybe,
if I'm feeling clever, I need to reset the ANI parameters on a given channel
during a transition through INIT or if the VAP is destroyed/re-created.
However for now this gets me out of the immediate weeds with connectivity
upstairs (and thus I /can/ commit); I'll keep chipping away at tidying this
stuff up in subsequent commits.
Tested:
* AR9344 (Wasp), 2G STA mode
Have the final attempted rate in 11n modes to be the lowest one.
Right now ath_rate_sample has a fixed rate schedule, rather than the minstrel_ht
style "best, good, most reliable" triplet. So, if higher rates are tried then
it'll not fail back to a lower MCS rate in that transmission schedule.
This means that in low SNR situations it'll not easily drop to MCS0 unless enough
transmissions occur to allow rate control to eventually decide to drop; and if
it's TCP traffic it'll get slowed down because of packet loss.
It's worse for 2-stream and 3-stream rates; it doesn't ever fall back to lower
stream rates, and these higher stream rates required higher SNR to work.
So instead let's (for now?) have each of the 11n transmit rates use MCS0 as
the last attempt. ath_rate_sample will quickly see that rate succeeds more
and will move to it much quicker.

Yes, people shouldn't use bitfields in C for structure parsing.
If someone ever wants a cleanup task then it'd be great to remove them
from this vendor code and other places in the ar9285/ar9287 HALs.
Alas, here we are.
AH_BYTE_ORDER wasn't defined and neither were the two values it could be.
So when compiling ath_ee_print_9300 it'd default to the big endian struct
layout and get a WHOLE lot of stuff wrong.
So:
* move AH_BYTE_ORDER into ath_hal/ah.h where it can be used by everyone.
* ensure that AH_BYTE_ORDER is actually defined before using it!
This should work on both big and little endian platforms.
Add some extra data into the rate control lookup.
Right now (well, since I did this in 2011/2012) the rate control code
makes some super bad choices for 11n aggregates/rates, and it tracks
statistics even more questionably.
It's been long enough and I'm now trying to use it again daily, so let's
start by:
* telling the rate control code if it's an aggregate or not;
* being clearer about the TID - yes it can be extracted from the
ath_buf but this way it can be overridden by the caller without
changing the TID itself.
(This is for doing experiments with voice/video QoS at some point..)
* Return an optional field to limit how long the aggregate is in
microseconds. Right now the rate control code supplies a rate table
and the ath aggr form code will look at the rate table and limit
the aggregate size to 4ms at the slowest rate. Yeah, this is pretty
terrible.
* Add some more TODO comments around handling txpower, rate and
handling filtered frames status so if I continue to have spoons for
this I can go poke at it.
Extend ath_rate_sample to better handle 11n rates and aggregates.
My initial rate control code was .. suboptimal. I wanted to at least get MCS
rates sent, but it didn't do anywhere near enough to handle low signal level links
or remotely keep accurate statistics.
So, 8 years later, here's what I should've done back then.
* Firstly, I wasn't at all tracking packet sizes other than the two buckets
(250 and 1600 bytes.) So, extend it to include 4096, 8192, 16384, 32768 and
65536. I may go add 2048 at some point if I find it's useful.
This is important for a few reasons. First, when forming A-MPDU or AMSDU
aggregates the frame sizes are larger, and thus the TX time calculation
is woefully, increasingly wrong. Secondly, the behaviour of 802.11 channels
isn't some fixed thing, both due to channel conditions and radios themselves.
Notably, there was some observations done a few years ago on 11n chipsets
which noticed longer aggregates showed an increase in failed A-MPDU sub-frame
reception as you got further along in the transmit time. It could be due to
a variety of things - transmitter linearity, channel conditions changing,
frequency/phase drift, etc - but the observation was to potentially form
shorter aggregates to improve BER.
* .. and then modify the ath TX path to report the length of the aggregate sent,
so as the statistics kept would line up with the correct bucket.
* Then on the rate control look-up side - i was also only using the first frame
length for an A-MPDU rate control lookup which isn't good enough here.
So, add a new method that walks the TID software queue for that node to
find out what the likely length of data available is. It isn't ALL of the
data in the queue because we'll only ever send enough data to fit inside the
block-ack window, so limit how many bytes we return to roughly what ath_tx_form_aggr()
would do.
* .. and cache that in the first ath_buf in the aggregate so it and the eventual
AMPDU length can be returned to the rate control code.
* THEN, modify the rate control code to look at them both when deciding which bucket
to attribute the sent frame on. I'm erring on the side of caution and using the
size bucket that the lookup is based on.
Ok, so now the rate lookups and statistics are "more correct". However, MCS rates
are not the same as 11abg rates in that they're not a monotonically incrementing
set of faster rates and you can't assume that just because a given MCS rate fails,
the next higher one wouldn't work better or be a lower average tx time.
So, I had to do a bunch of surgery to the best rate and sample rate math.
This is the bit that's a WIP.
* First, simplify the statistics updates (update_stats()) to do a single pass on
all rates.
* Next, make sure that each rate average tx time is updated based on /its/ failure/success.
Eg if you sent a frame with { MCS15, MCS12, MCS8 } and MCS8 succeeded, MCS15 and MCS
12 would have their average tx time updated for /their/ part of the transmission,
not the whole transmission.
* Next, EWMA wasn't being fully calculated based on the /failures/ in each of the
rate attempts. So, if MCS15, MCS12 failed above but MCS8 didn't, then ensure
that the statistics noted that /all/ subframes failed at those rates, rather than
the eventual set of transmitted/sent frames. This ensures the EWMA /and/ average
TX time are updated correctly.
* When picking a sample rate and initial rate, probe rates aroud the current MCS
but limit it to MCS0..7 /for all spatial streams/, rather than doing crazy things
like hitting MCS7 and then probing MCS8 - MCS8 is basically MCS0 but two spatial
streams. It's a /lot/ slower than MCS7. Also, the reverse is true - if we're at
MCS8 then don't probe MCS7 as part of it, it's not likely to succeed.
* Fix bugs in pick_best_rate() where I was /immediately/ choosing the highest MCS
rate if there weren't any frames yet transmitted. I was defaulting to 25% EWMA and
.. then each comparison would accept the higher rate. Just skip those; sampling
will fill in the details.
So, this seems to work a lot better. It's not perfect; I'm still seeing a lot of
instability around higher MCS rates because there are bursts of loss/retransmissions
that aren't /too/ bad. But i'll keep iterating over this and tidying up my hacks.
Ok, so why this still something I'm poking at? rather than porting minstrel_ht?
ath_rate_sample tries to minimise airtime, not maximise throughput. I have
extended it with an EWMA based on sub-frame success/failures - high MCS rates
that have partially successful receptions still show super short average frame
times, but a /lot/ of retransmits have to happen for that to work.
So for MCS rates I also track this EWMA and ensure that the rates I'm choosing
don't have super crappy packet failures. I don't mind not getting lower
peak throughput versus minstrel_ht; instead I want to see if I can make "minimise
airtime" work well.
Tested:
* AR9380, STA mode
* AR9344, STA mode
* AR9580, STA/AP mode
le oops, trim out an #if 1 that I didn't fully delete.
Cool, so now I know it's about 3 weeks between starting on freebsd coding
and breaking the build again. Queue dunce cap.
Fix logic for determining whether to bump up an MCS rate.
* Fix formatting, cause reasons;
* Put back the "and the chosen rate is within 90% of the current rate" logic;
* Ensure the best rate and the current rate aren't the same; this ...
* ... fixes the packets_since_switch[] tracking to actually conut how many
frames since the rate switched, so now I know how stable stuff is; and
* Ensure that MCS can go up to a higher MCS at this or any other spatial stream.
My previous quick hack attempt was doing > rather than >= so you had to go
to both a higher root MCS rate (0..7) and spatial stream. Eg, you couldn't
go from MCS0 (1ss) to MCS8 (2ss) this way.
The best rate and switching rate logic still have a bunch more work to do
because they're still quite touchy when it comes to average tx time but at least
now it's choosing higher rates correctly when it wants to try a higher rate.
Tested:
* AR9380, STA mode
Limit the tx schedules for A-MPDU ; don't take short retries into account and remove the requirement that the MCS rate is "higher" if we're considering a new rate.
Ok, another fun one.
* In order for reliable non-software retried higher MCS rates, the TX schedules
(inconsistently!) use hard-coded lower rates at the end of the schedule.
Now, hard-coded is a problem because (a) it means that aggregate formation
is limited by the SLOWEST rate, so I never formed large AMDU frames for
3 stream rates, and (b) if the AP disables lower rates as base rates, it
complains about "unknown rix" every frame you transmit at that rate.
So, for now just disable the third and fourth schedule entry for AMPDUs.
Now I'm forming 32k and 64k aggregates for the higher density MCS rates
much more reliably.
It would be much nicer if the rate schedule stuff wasn't fixed but instead
I'd just populate ath_rc_series[] when I fetch the rates. This is all a
holdover of ye olde pre-11n stuff and I really just need to nuke it.
But for now, ye hack.
* The check for "is this MCS rate better" based on MCS itself is just garbage.
It meant things like going MCS0->7 would be fine, and say 0->8->16 is fine,
(as they're equivalent encoding but 1,2,3 spatial streams), BUT it meant
going something like MCS7->11 would fail even though it's likely that
MCS11 would just be better, both for EWMA/BER and throughput.
So for now just use the average tx time. The "right" way for this comparison
would be to compare PHY bitrates rather than MCS / rate indexes, but I'm not
yet there. The bit rates ARE available in the PHY index, but honestly
I have a lot of other cleaning up to here before I think about that.
* Don't include the RTS/CTS retry count (and thus time) into the average tx time
caluation. It just makes temporarily failures make the rate look bad by
QUITE A LOT, as RTS/CTS exchanges are (a) long, and (b) mostly irrelevant
to the actual rate being tried. If we keep hitting RTS/CTS failures then
there's something ELSE wrong on the channel, not our selected rate.
Fix correct status when completing frames with short failures.
My preivous logic was a bit wrong. This caused transmissions that failed due
to a mix of short and long retries to count intermediate rates as OK if the
LONG retry count indicated some retries had made it to this intermediate rate,
but the SHORT retry count was the one that caused the whole transmit to fail.
Now status is passed in again - and this is the status for the whole transmission -
and then update_stats() does some quick math to see if the current transmission
series hit its long retry count or not before updating things as a success
or failure.
Obey the maximum frame length even when using static rates.
I wasn't enforcing the maximum packet length when using static rates
so although the driver was enforcing it itself OK, the statistics were
sometimes going into the wrong bin.
Tested:
* AR9380, STA mode
reset hardware if this particular mac bug is seen.
I have to dig into why I'm seeing it on chips as late as the AR9380 era
stuff (as it's marked as an AR5416 bug, but who knows!) but i'm seeing
aggregate TX frames complete with no blockack bit set. So, everything
should be treated as a failure and do a hardware reset for good measure.
Tested:
* AR9380, STA mode
* AR9580 (5GHz), AP mode
Hopefully recover better-er upon RX restart on AR9380.
This is all very long-standing bug stuff that is touchy and still poorly
documented. Ok, here goes.
The basic bug:
* deleting a VAP causes the RX path (and TX path too) to be restarted
without a full chip reset, which causes RX hangs on the AR9380 and later.
(ie, the ones with the newer DMA engine.)
The basic fix:
* do an RX flush when stopping RX in ath_vap_delete() to match what happens
when RX is stopped elsewhere. This ensures any pending frames are completed
and we restart at the right spot; it also ensures we don't push new RX buffers
into the hardware if we're stopping receive.
The other issues I found:
* Don't bother checking the RX packet ring in the deferred read taskqueue;
that's specifically supposed to be for completing frames rather than
just yanking them off the receive ring.
* Cancel/drain any pending deferred read taskqueue. This isn't done inside
any locks so we should be super careful here. This stops the hardware
being reprogrammed at the same time in another thread/CPU whilst we're
stopping RX.
* .. (yes, this should be better serialised, but that's for another day. maybe.)
* Add more debugging to trace what's going on here.
And the fun bit:
* Reinitialise the RX FIFO ONLY if we've been reset or stopped, rather than just
reset. I noticed that after all the above was done I was STILL seeing RXEOL.
RXEOL isn't enabled on the AR9380 so I'd only see it if I was sending TX frames
(ie a ping where it'd be transmitted but never received) so I was not being
spammed by RXEOL. So, as long as stuff is stopped, restart it.
This seems to be doing the right thing in both AP and STA modes.
What I should do next, if I ever get time:
* as I said above, serialise the receive stop/start to include taskqueues
* monitor RXEOL on the AR9380 and I keep seeing it spammed / lockups, just
go do a full chip reset to get things back on track. It sucks, but it
is better than nothing.
Tested:
* AR9380 AP/STA mode, adding/deleting a hostap VAP to trigger the TX/RX
queue stop/start; whilst also running an iperf through it. Lots of times.
Lots. Of.. Times.
Propagate the HAL_RESET_TYPE through to the chip reset; set it during ath_reset()
Although I added the reset type field to ath_hal_reset() years ago,
I never finished adding it both throughout the HALs and in if_ath.c.
This will eventually deprecate the ath_hal force_full_reset option
because it can be requested at the driver layer.
So:
* Teach ar5416ChipReset() and ar9300_chip_reset() about the HAL type
* Use it in ar5416Reset() and ar9300_reset() when doing a full chip reset
* Extend ath_reset() to include the HAL_RESET_TYPE parameter added in the above functions
* Use HAL_RESET_NORMAL in most calls to ath_reset()
* .. but use HAL_RESET_BBPANIC for the BB panics, and HAL_RESET_FORCE_COLD during fatal, beacon miss and other hardware related hangs.
This should be a glorified no-op outside of actual hardware issues.
I've tested things with ath_hal force_full_reset set to 1 for years now,
so I know that feature and a full reset works (albeit much slower than
a warm reset!) and it does unwedge hardware.
The eventual aim is to use this for all the places where the driver
detects a potential hang as well as if long calibration - ie, noise floor
calibration - fails to complete. That's one of the big hardware related
things that causes station mode operation to hang without easy recovery.

Update ath_rate_sample to use the same base type as ticks.
Until net80211 grows a specific ticks type that matches the system,
manually use the same type as the kernel/net80211 'ticks' type
(signed int.)
Tested:
* AR9380, STA mode
Don't re-program the beacon timers if we miss a beacon in software-beacon STA mode.
This is something I added a few years ago to handle resyncing the beacon if
we miss a beacon or need to sync after association/reassociation/powersave.
However, if we're doing STA+AP mode (eg DWDS) then we don't want
to reprogram the beacons here; this may upset normal AP operation.
I missed checking for the sc->sc_swbmiss flag so I was reinitialising
the beacon timers after every beacon miss / TSFOOR option, and
that isn't likely good.
This plus ensuring that STA's are created with "-beacon" to disable
BMISS/TSFOOR processing will hopefully quieten some of the issues
I've seen with missed beacons / TSFOOR (out of range) interrupts
coming in when operating in STA mode.
Tested:
* AR9380/AR9580, STA+AP modes
Don't update the beacon bits from beacon frames in hostapd mode.
This logic is running the beacon receive bits in STA+AP mode on both the
STA and AP side. The STA side sees its beacons from the BSS fine; the
AP side is seeing other beacons on the same channel but with the BSS
node for some odd reason. (I think it's a valid reason, but I currently
forget what that valid reason is.)
So, just to be cleaner about things, don't run the nexttbtt/etc bits
at all if we're in hostap mode. If I ever get mesh working then maybe
I'll make sure it works right on mesh+ap and mesh+sta modes.
Whilst here, log the VAP i'm being called on to make it clearer what
is going on. I may end up adding a VAP dprintf version of this at
some point.
Tested:
* AR9380, STA (DWDS client) + hostap on the same NIC
Add KeyMiss for AR5212/AR5416 series chips.
This is a flag from the MAC that says the received packet didn't match
a keycache slot. This isn't technically a problem as WEP keys don't
match keycache slots (they're "global" keys), but it could be useful
for tracking down CCMP decryption failures.
Right now it's a no-op - it mirrors what the AR9300 HAL does and it
just increments a counter. But, hey, maybe one day I'll use it for
diagnosing keycache/CCMP decrypt issues.

replace the hard-coded magic values in if_athioctl.h with constant defines
Replace some hard-coded magic values in the ioctl stats struct with
defines. I'm going to follow up with some more sanity checking in
the receive path that also use these values so we don't do bad
things if the hardware is (more) confused.
Don't use hard-coded values in the sanity check.
Don't use hard-coded values in the phy error and receive antenna
checks.
also remove the magic size value here for the transmit antenna statistics.

iwn(4): (partially) rewrite A-MPDU Tx path
Generic Tx stats fixes:
- do not try to parse "aggregation status" for single frames; send them
to iwn_tx_done() instead;
- try to attach mbuf / node reference pair to reported BA events;
allows to fix reported status for ieee80211_tx_complete() and ifnet counters
(previously all A-MPDU frames were counted as failed - see PR 210211);
requires few more firmware bug workarounds;
- preserve short / long retry counters for wlan_amrr(4)
(disabled for now - causes significant performance degradation).
- Add new IWN_DEBUG_AMPDU debug category.
- Add one more check into iwn_tx_data() to prevent aggregation ring
overflow.
- Workaround 'seqno % 256' != 'current Tx slot' case (until D9195 is not
in the tree).
- Improve watchdog timer updates (previously watchdog check was omitted
when at least one frame was transmitted).
- Stop Tx when memory leak in currently used ring was detected (unlikely
to happen).
- Few other minor fixes.
Was previously tested with:
- Intel 6205, STA mode (Tx aggregation behaves much better now).
- Intel 4965AGN, STA mode (still unstable).

Fix ieee80211_radiotap(9) usage in wireless drivers:
- Alignment issues:
* Add missing __packed attributes + padding across all drivers; in
most places there was an assumption that padding will be always
minimally suitable; in few places - e.g., in urtw(4) / rtwn(4) -
padding was just missing.
* Add __aligned(8) attribute for all Rx radiotap headers since they can
contain 64-bit TSF timestamp; it cannot appear in Tx radiotap headers, so
just drop the attribute here. Refresh ieee80211_radiotap(9) man page
accordingly.
- Since net80211 automatically updates channel frequency / flags in
ieee80211_radiotap_chan_change() drop duplicate setup for these fields
in drivers.
Tested with Netgear WG111 v3 (urtw(4)), STA mode.
