22dd2fd283 iwlwifi: remove duplicate initialization in __iwl_down()
We initialize exit_pending twice.  It's the second initialization which
is correct.  That was added in d745d472af "iwlwifi: cancel scan when
down the device".

ffd8c746fb iwlegacy: fix bugs in change_interface
If change_interface gets invoked during a firmware
restart, it may crash; prevent that from happening
by checking if ctx->vif is assigned.

Additionally, in my initial commit I forgot to set
the vif->p2p variable correctly, so fix that too.

24047e2c4f carl9170: Fix tx aggregation problems with some clients
Some clients seem to rely upon the reception of BlockAckReqs to flush
their rx reorder buffer. In order to fix aggregation for these clients
carl9170 should set IEEE80211_TX_STAT_AMPDU_NO_BACK to generate a
BlockAckReq if the transmission of an AMPDU subframe fails.

This fixes aggregation problems with Intel 5100 Windows STAs (and maybe
others as well).

0263aa4529 iwl3945: disable hw scan by default
After new NetworkManager 0.8.996 changes, hardware scanning is causing
microcode errors as reported here:
https://bugzilla.redhat.com/show_bug.cgi?id=683571
and sometimes kernel crashes:
https://bugzilla.redhat.com/show_bug.cgi?id=688252

Also with hw scan there are very bad performance on some systems
as reported here:
https://bugzilla.redhat.com/show_bug.cgi?id=671366

Since Intel no longer supports 3945, there is no chance to get proper
firmware fixes, we need workaround problems by disable hardware scanning
by default.

d0eb633431 iwlwifi: cleanup and bugfix tx aggregation code
Since the driver split, there's no need for no_agg_framecnt_info since
all devices have this set to false. Secondly, the compressed block ack
handling code was broken. Fix this.

(1) A shift less than zero simply implies that the buffer wrapped, this
is expected. Remove the incorrect comment.

(2) The (agg->frame_count > (64-sh)) condition can happen if the last
frame is dropped. E.g., if I send 7 frames and the 6th is received but
the 7th is lost, the other side may only shift the window 6, not 7
frames since the last bit is a 0. This is perfectly fine behavior and
doesn't invalidate the feedback.

(3) Store the feedback from a Compressed BA in the first newly received
frame, rather than the start of the window. This way it will get
processed by the rate selection code. Feedback stored in a non-received
frame is likely to get overwritten by the retransmission.
    This is based on the approach taken by minstrel_ht.

374920cb05 iwlwifi: limit number of attempts for highest HT rate
When filling out its rate scale table, iwlwifi repeats the first HT rate
IWL_HT_NUMBER_TRY times. The hardware scheduler will stop using
aggregation for any frame that fails LINK_QUAL_AGG_DISABLE_START_DEF
times. Currently, both these constants equal 3.

If iwlwifi probes a faster rate than the link supports, all frames in a
(potentially tens of frames large) batch will fail IWL_HT_NUMBER_TRY
times. Because this happens to be as large as
LINK_QUAL_AGG_DISABLE_START_DEF, all frames will then be sent
individually. This leads to a short, but performance-degrading window
where the legacy stop-and-wait MAC takes over.

Bounding the initial rate by (LINK_QUAL_AGG_DISABLE_START_DEF-1)
attempts makes the third try use a lower rate and hence more be likely
to succeed. This somewhat mitigates the above described behavior.

d78f4b3e2c ath9k: Fix TX queue stuck issue.
commit 86271e460a introduced a
regression that caused mac80211 queues in stopped state.

ath_drain_all_txq is called in driver flush which would reset
the stopped flag and the mac80211 queues were never started
after that. iperf traffic is completely stalled due to this issue.

Restart the mac80211 queues in driver flush only if the txqs were
drained.

19b9675069 ath9k: Fix kernel panic caused by invalid rate index access.
With the recent tx status optimization in mac80211, we bail out as
and and when invalid rate index is found. So the behavior of resetting
rate idx to -1 and count to 0 has changed for the rate indexes that
were not part of the driver's retry series.

This has resulted in ath9k using incorrect rate table index which
caused the system to panic. Ideally ath9k need to loop only for the
indexes that were part of the retry series and so simply use hw->max_rates
as the loop counter.

Pasted the stack trace of the panic issue for reference.

7d2c16befa ath9k: fix aggregation related interoperability issues
Some clients seems to keep track of their reorder window even after an
aggregation session has been disabled. This causes issues if there are
still retried but not completed frames pending for the TID.
To ensure that rx does not stall in such situations, set sendbar to 1
for any frame purged from the TID queue on teardown.

efff395e97 ath9k: improve reliability of beacon transmission and stuck beacon handling
ath9k calls ath9k_hw_stoptxdma every time it sends a beacon, however there
is not much point in doing that if the previous beacon and mcast traffic
went out properly. On AR9380, calling that function too often can result
in an increase of stuck beacons due to differences in the handling of the
queue enable/disable functionality.

With this patch, the queue will only be explicitly stopped if the previous
data frames were not sent successfully. With the beacon code being the
only remaining user of ath9k_hw_stoptxdma, this function can be simplified
in order to remove the now pointless attempts at waiting for transmission
completion, which would never happen at this point due to the different
method of tx scheduling of the beacon queue.

0d51cccc24 ath9k: fix stopping tx dma on reset
In some situations, stopping Tx DMA frequently fails, leading to messages
like this:

ath: Failed to stop TX DMA in 100 msec after killing last frame
ath: Failed to stop TX DMA!

This patch uses a few MAC features to abort DMA globally instead of iterating
over all hardware queues and attempting to stop them individually.
Not only is that faster and works with a shorter timeout, it also makes the
process much more reliable.

With this change, I can no longer trigger these messages on AR9380,
and on AR9280 they become much more rare.

d89dba7a27 libertas: fix write past end of array in mesh_id_get()
defs.meshie.val.mesh_id is 32 chars long.  It's not supposed to be NUL
terminated.  This code puts a terminator on the end to make it easier to
print to sysfs.  The problem is that if the mesh_id fills the entire
buffer the original code puts the terminator one spot past the end.

The way the original code was written, there was a check to make sure
that maxlen was less than PAGE_SIZE.  Since we know that maxlen is at
most 34 chars, I just removed the check.

2e286947f1 ath9k: remove support for the FIF_PROMISC_IN_BSS filter flag
The hardware rx filter flag triggered by FIF_PROMISC_IN_BSS is overly broad
and covers even frames with PHY errors. When this flag is enabled, this message
shows up frequently during scanning or hardware resets:

ath: Could not stop RX, we could be confusing the DMA engine when we start RX up

Since promiscuous mode is usually not particularly useful, yet enabled by
default by bridging (either used normally in 4-addr mode, or with hacks
for various virtualization software), we should sacrifice it for better
reliability during normal operation.

This patch leaves it enabled if there are active monitor mode interfaces, since
it's very useful for debugging.

5f6722ee63 wl1251: fix elp_work race condition
While working on PS I've noticed elp_work is kicking rather often, and
sometimes the chip is put to sleep before 5ms delay expires. This
seems to happen because by the time wl1251_ps_elp_wakeup is called
elp_work might still be pending. After wakeup is done, the processing
may take some time, during which 5ms might expire and elp_work might
get scheduled. In this case, ss soon as 1st thread finishes work and
releases the mutex, elp_work will then put the device to sleep without
5ms delay. In addition 1st thread will queue additional elp_work
needlessly.

Fix this by cancelling work in wl1251_ps_elp_wakeup instead.

d0c331aff9 wl1251: remove wl1251_ps_set_elp function
wl1251_ps_set_elp() only does acx_sleep_auth call and takes the chip
from/to ELP, however all callers of wl1251_ps_set_mode() have already
taken the chip out of ELP and puts it back to ELP when they finish.
This makes ELP calls (and register writes they result in) superfluous.

So remove wl1251_ps_set_elp function and call acx_sleep_auth directly.

410f2bb30d iwlwifi: avoid too frequent recover from statistics
Usually H/W generate statistics notify once per about 100ms, but
sometimes we can receive notify in shorter time, even 2 ms.

This can be problem for plcp health and ack health checking.

I.e. with 2 plcp errors happens randomly in 2 ms duration, we
exceed plcp delta threshold equal to 100 (2*100/2).

Also checking ack's in short time, can results not necessary false
positive and firmware reset, for example when channel is noised and
we do not receive ACKs frames or when remote device does not send
ACKs at the moment.

Patch change code to do statistic check and possible recovery only
if 99ms elapsed from last check. Forced delay should assure we have
good statistic data to estimate hardware state.

a24408307e rt2x00: Optimize getting the beacon queue structure.
In the spirit of optimizing the code to get the queue structure of TX queues,
also optimize the code to get beacon queues. We can simply use the bcn queue
field of the rt2x00_dev structure instead of using the rt2x00queue_get_queue
function.

The ATIM queue is considered to be a TX queue by the drivers that support
the queue. Therefore include support for the ATIM queue to the
rt2x00queue_get_tx_queue function so that the drivers that support the ATIM
queue can also use that function.

Add the support in such a way that drivers that do not support the ATIM

previously used the STAs AID to select an appropriate key slot. But
since the AID is per VIF we can end up with two STAs having the same AID

the key information of another STA.

Fix this by simply searching for the next unused entry in the pairwise
key table.

2da69b890f wl12xx: Switch to level trigger interrupts
The interrupt of the wl12xx is a level interrupt in nature, since the
interrupt line is not auto-reset. However, since resetting the interrupt
requires bus transactions, this cannot be done from an interrupt
context. Thus, requesting a level interrupt would require to disable the
irq and re-enable it after the HW is acknowledged. Since we now request
a threaded irq, this can also be done by specifying the IRQF_ONESHOT
flag.

Triggering on an edge can be problematic in some platforms, if the
sampling frequency is not sufficient for detecting very frequent
interrupts. In case an interrupt is missed, the driver will hang as the
interrupt line will stay high until it is acknowledged by the driver,
which will never happen.

Fix this by requesting a level triggered interrupt, with the
IRQF_ONESHOT flag.

a620865edf wl12xx: Switch to a threaded interrupt handler
To achieve maximal throughput, it is very important to react to
interrupts as soon as possible. Currently the interrupt handler wakes up
a worker for handling interrupts in process context. A cleaner and more
efficient design would be to request a threaded interrupt handler.  This
handler's priority is very high, and can do blocking operations such as
SDIO/SPI transactions.

Some work can be deferred, mostly calls to mac80211 APIs
(ieee80211_rx_ni and ieee80211_tx_status). By deferring such work to a
different worker, we can keep the irq handler thread more I/O
responsive. In addition, on multi-core systems the two threads can be
scheduled on different cores, which will improve overall performance.

The use of WL1271_FLAG_IRQ_PENDING & WL1271_FLAG_IRQ_RUNNING was
changed. For simplicity, always query the FW for more pending
interrupts. Since there are relatively long bursts of interrupts, the
extra FW status read overhead is negligible. In addition, this enables
registering the IRQ handler with the ONESHOT option.

393fb560d3 wl12xx: Change claiming of the SDIO bus
The SDIO bus is claimed and released for each SDIO transaction. In
addition to the few CPU cycles it takes to claim and release the bus, it
may also cause undesired side effects such as the MMC host stopping its
internal clocks.

Since only the wl12xx_sdio driver drives this SDIO card, it is safe to
claim the SDIO host once (on power on), and release it only when turning
the power off.

This patch was inspired by Juuso Oikarinen's (juuso.oikarinen@nokia.com)

On newer hardware revisions, there is no need to write the host's

8aad24642a wl12xx: Reorder data handling in irq_work
The FW has a limited amount of memory for holding frames. In case it
runs out of memory reserved for RX frames, it'll have no other choice
but to drop packets received from the AP. Thus, it is important to
handle RX data interrupts as soon as possible, before handling anything
else.

In addition, since there are enough TX descriptors to go around, it is
better to first send TX frames, and only then handle TX completions.

Fix this by changing the order of function calls in wl1271_irq_work.

11251e7e5c wl12xx: Don't rely on runtime PM for toggling power
Runtime PM might not always be enabled. Even if it is enabled in the
running kernel, it can still be temporarily disabled, for instance
during suspend. Runtime PM is opportunistic in nature, and should not be
relied on for toggling power.

In case the interface is removed and re-added while runtime PM is
disabled, the FW will fail to boot, as it is mandatory to toggle power
between boots. For instance, this can happen during suspend in case one
of the devices fails to suspend before the MMC host suspends, but after
mac80211 was suspended. The interface will be removed and reactivated
without toggling the power.

Fix this by calling mmc_power_save_host/mmc_power_restore_host in
wl1271_sdio_power_on/off functions. It will toggle the power to the chip
even if runtime PM is disabled. The runtime PM functions should still be
called to make sure runtime PM does not opportunistically power the chip
off (e.g. after resuming from system suspend).

375ff4c778 rtlwifi: Fix error registering rate-control
When a second module such as rtl8192ce or rtl8192cu links to rtlwifi, the attempt
to register a rate-control mechanism fails with the warning shown below. The fix is to
select the RC mechanism when rtlwifi is initialized.

I still can observe above warning after apply patch, but it is very
hard to reproduce it, and have count=1. Whereas that one is easy to
reproduce using debugfs force_reset while transmitting data, and have
very big counts eg. 240, like quoted here. So count=1 WARNING seems
to be different issue that need to be resolved separately.

c3371d64d2 iwlwifi: remove duplicate initialization
rate_mask is initialized again later so this can be removed.  Btw, if
rate_control_send_low(sta, priv_sta, txrc) returns false, that means
that "sta" is non-NULL.  That's why the second initialization of
rate_mask is a little simpler than the first.

3311abbbbf b43: fill PHY ctl word1 in TX header for N-PHY
This patch fixes tramissing on OFDM rates for PHYs 1 and 2. There is
still something wrong with PHYs 3+. Tests has shown decreasing of
performance on CCK rates by 1-2%, we have to live with that.
Additionaly this noticeably reduces amount of PHY errors. They were
mostly produced by auto-switching to higher rate for better
performanced, which resulted in no transmit at all and PHY errors.

850bedcc10 iwlagn: fix iwlagn_check_needed_chains
This function was intended to calculate the
number of RX chains needed, but could only
work where the AP's streams were asymmetric,
i.e. 2 TX and 3 RX or similar. In the case
where IEEE80211_HT_MCS_TX_RX_DIFF was not
set, this function would calculate the wrong
information.

Additionally, mac80211 didn't pass through
the required values at all, so it couldn't
work anyway.

Rewrite the logic in this function and add
appropriate comments to make it readable.

7bb4568372 mac80211: make tx() operation return void
The return value of the tx operation is commonly
misused by drivers, leading to errors. All drivers
will drop frames if they fail to TX the frame, and
they must also properly manage the queues (if they
didn't, mac80211 would already warn).

Removing the ability for drivers to return a BUSY
value also allows significant cleanups of the TX
TX handling code in mac80211.

Note that this also fixes a bug in ath9k_htc, the
old "return -1" there was wrong.

fw_status. Manually notify mac80211 about PS mode changes in connected
stations.

mac80211 will only be notified about PS start when the station is in PS
and there is a small number of TX blocks from this link ready in HW.
This is required for waking up the remote station since the TIM is
updated entirely by FW.

When a station enters mac80211-PS-mode, we drop all the skbs in the
low-level TX queues belonging to this sta with STAT_TX_FILTERED
to keep our queues clean.

09039f42a2 wl12xx: AP-mode - count free FW TX blocks per link
Count the number of FW TX blocks allocated per link. We add blocks to a
link counter when allocated for a TX descriptor. We remove blocks
according to counters in fw_status indicating the number of freed blocks
in FW. These counters are polled after each IRQ.

ba7c082a13 wl12xx: AP-mode - support HW based link PS monitoring
When operating in AP mode the wl1271 hardware filters out null-data
packets as well as management packets. This makes it impossible for
mac80211 to monitor the PS mode by using the PM bit of incoming frames.

Disable mac80211 automatic link PS-mode handling by supporting
IEEE80211_HW_AP_LINK_PS in HW flags.

1d36cd892c wl12xx: report invalid TX rate when returning non-TX-ed skbs
Report a TX rate idx of -1 and count 0 when returning untransmitted
skbs to mac80211 using ieee80211_tx_status(). Otherwise mac80211
tries to use the returned (essentially garbage) status.

a8c0ddb5ba wl12xx: AP-mode - TX queue per link in AC
When operating in AP-mode we require a per link tx-queue.
This allows us to implement HW assisted PS mode for links,
as well as regulate per-link FW TX blocks consumption.
Split each link into ACs to support future QoS for AP-mode.

AC queues are emptied in priority and per-link queues are
scheduled in a simple round-robin fashion.

99a2775d02 wl12xx: AP-mode - fix race condition on sta connection
If a sta starts transmitting immediately after authentication, sometimes
the FW deauthenticates it. Fix this by marking the sta "in-connection"
in FW before sending the autentication response.

The "in-connection" entry is automatically removed when connection
succeeds or after a timeout.

f4d08ddd3e wl12xx: fix potential race condition with TX queue watermark
Check the conditions for the high/low TX queue watermarks when the
spin-lock is taken. This prevents race conditions as tx_queue_count and
the flag checked are only modified when the spin-lock is taken.

The following race was in mind:
- Queues are almost full and wl1271_op_tx() will stop the queues, but it
  doesn't get the spin-lock yet.
- (on another CPU) tx_work_locked() dequeues 15 skbs from this queue and
  tx_queue_count is updated to reflect this
- wl1271_op_tx() does not check tx_queue_count after taking the
  spin-lock and incorrectly stops the queue.
