When entering D3, we need to use hardcoded key indices because the
firmware requires that. To do so, we are overwriting the HW key index
in the keyconf structure, which makes it impossible to reuse the
indices that were used before entering D3. Additionally, we overwrite
all the non-PTK keys with index 1, because the firmware only allows
one non-PTK key to be set. This is bad, because when we resume, we
may try to set more than one key with index 1, which will obviously
fail.
To fix this, allow the callers to set a pre-defined index to use in
iwl_mvm_set_sta_key() instead of relying on the hw_key_idx value from
the keyconf struct (which requires overwriting it). In normal cases,
the caller can pass STA_KEY_IDX_INVALID, which will cause a new key
offset to be chosen. During HW_RESTART, we pass the offset that is in
use. And during D3 entry, we pass the hardcoded indices we need to
use.
Additionally, don't clear the fw_key_table in D3 entry, so that the
flags are still set with the pre-D3 values when exiting D3.

Of a word in struct htt_data_tx_desc htt version >= 3.4 firmware uses
LSB 16-bit for frequency configuration which is used for offchannel tx
and MSB 16-bit is for peerid. But other firmwares using version 2.X
(10.1, 10.2.2, 10.2.4 and 10.4) are using 32-bit for peerid in htt tx
desc. So far no issue is found with the existing code setting peerid and
freq for HTT version 2.X, this could be mainly because of 0 as frequecy
(home channel) is being always passed with those firmwares. There may be
issues when non-zero freq is passed with firmware using < 3.4 htt version.
To be safe use target_version_major and target_version_minor along with
htt-op-version before configuring peer id and freq in htt tx desc. This
patch extends ath10k_mac_tx_frm_has_freq() to check for htt_op_version_tlv
and uses the helper while setting peerid in htt_tx_desc.

command interface brings in a new wmi_ops for 10.4 gen_peer_assoc().

European Union has made it mandatory that all devices working in 2.4 GHz
has to adhere to the ETSI specification (ETSI EN 300 328 V1.9.1)
beginnig this year. The standard basically speaks about interferences
in 2.4Ghz band.
For example, when 802.11 device detects interference, TX must be stopped
as long as interference is present.
Adaptive CCA is a feature, when enabled the device learns from the
environment and configures CCA levels adaptively. This will improve
detecting interferences and the device can stop trasmissions till the
interference is present eventually leading to good performances in
varying interference conditions.
The patch includes code for enabling adaptive CCA for 10.2.4 firmware on
QCA988X.

ssb bus can be found on various "host" devices like PCI/PCMCIA/SDIO.
Every ssb bus contains cores AKA devices.
The main idea is to have ssb driver scan/initialize bus and register
ready-to-use cores. This way ssb drivers can operate on a single core
mostly ignoring underlaying details.
For some reason PCMCIA support was split between ssb and b43. We got
PCMCIA host device probing in b43, then bus scanning in ssb and then
wireless core probing back in b43. The truth is it's very unlikely we
will ever see PCMCIA ssb device with no 802.11 core but I still don't
see any advantage of the current architecture.
With proposed change we get the same functionality with a simpler
architecture, less Kconfig symbols, one killed EXPORT and hopefully
cleaner b43. Since b43 supports both: ssb & bcma I prefer to keep ssb
specific code in ssb driver.
This mostly moves code from b43's pcmcia.c to bridge_pcmcia_80211.c. We
already use similar solution with b43_pci_bridge.c. I didn't use "b43"
in name of this new file as in theory any driver can operate on wireless
core.

In uap mode the carrier is not enabled until after the first STA joins.
The carrier triggers the bridge to start its state machine, and if STP
is enabled, it takes 4 seconds as it transitions from disabled to
forwarding. During this time the bridge drops all traffic, and the EAPOL
handshake times out after 3 seconds, preventing stations from joining.
Follow the logic used in mac80211 and start the carrier in start_ap
and disable it in stop_ap. This has a nice benefit of allowing the
first station connection time to be reduced by up to 75% when STP is
in use.

(high and low priority) DMA channel. The ring buffers are lockless:
new frames are inserted at the head of the queue, while finished
packets are reaped from the tail.
Unfortunately, the list manipulations are missing any kind of barriers
so are susceptible to various races: for example, a TX completion
handler might read an updated desc->ctrl before the head has actually
advanced, and then null out the ctl->skb pointer while it is still
being used in the TX path.
Simplify things here by adding a spin lock when traversing the ring.
This change increased stability for me without adding any noticeable
overhead on my platform (xperia z).

Some of the ath9k_phyerr enums were wrong from the
beginning (and even before). Most of the time the
codes were used for counters to be displayed over
debugfs, which made this a non-functional issue.
Some (e.g. ATH9K_PHYERR_FALSE_RADAR_EXT) are used
for radar detection and require the correct code
to work as intended.
This patch includes:
a) fixes
ATH9K_PHYERR_FALSE_RADAR_EXT: 24 => 36
ATH9K_PHYERR_CCK_LENGTH_ILLEGAL: 32 => 28
ATH9K_PHYERR_CCK_POWER_DROP: 33 => 29
ATH9K_PHYERR_HT_CRC_ERROR: 34 => 32
ATH9K_PHYERR_HT_LENGTH_ILLEGAL: 35 => 33
ATH9K_PHYERR_HT_RATE_ILLEGAL: 36 => 34
b) extensions
ATH9K_PHYERR_CCK_BLOCKER = 24
ATH9K_PHYERR_HT_ZLF = 35
ATH9K_PHYERR_GREEN_FIELD = 37
Aside from the correction and completion made in
the enum, the patch also extends the display of
the related counters in the debugfs.

SIOCSIWAP (airo_set_wap) affects scan: only the AP specified by
SIOCSIWAP is present in scan results.
This makes NetworkManager work for the first time but then unable to
find any other APs.
Clear APList before starting scan and set it back after scan completes
to work-around the problem.
To avoid losing packets during scan, modify disable_MAC() to omit
netif_carrier_off() call when lock == 2.

This is an alternate driver for a number of Realtek WiFi USB devices,
including RTL8723AU, RTL8188CU, RTL8188RU, RTL8191CU, and RTL8192CU.
It was written from scratch utilizing the Linux mac80211 stack.
After spending months cleaning up the vendor provided rtl8723au
driver, which comes with it's own 802.11 stack included, I decided to
rewrite this driver from the bottom up.
Many thanks to Johannes Berg for 802.11 insights and help and Larry
Finger for help with the vendor driver.
The full git log for the development of this driver can be found here:
git git://git.kernel.org/pub/scm/linux/kernel/git/jes/linux.git
branch rtl8723au-mac80211
This driver is still under development, but has proven to be very
stable for me. It currently supports station mode only. It has support
for OFDM and CCK rates. It does lack certain features found in the
staging driver, such as power management, AMPDU, and 40MHz channel
support. In addition it does not support AD-HOC, AP, and monitor mode
support at this point.
The driver is known to work with the following devices:
Lenovo Yoga (rtl8723au)
TP-Link TL-WN823N (rtl8192cu)
Etekcity 6R (rtl8188cu)
Daffodil LAN03 (rtl8188cu)

This patch disables PCI PS for QCA988X and QCA99X0, Since PCI PS is
validated for QCA6174, let it be enabled only for QCA6174. It would be
better to execute PCI PS related functions only for the supported devices.
PCI time out issue is observed with QCA99X0 on x86 platform, We will
disable PCI PS for QCA988X and QCA99X0 until PCI PS is properly implemented.
Taking and releasing ps_lock is causing higher CPU consumption. Michal Kazior
suggested ps_lock overhead to be reworked so that ath10k_pci_wake/sleep
functions are called less often, i.e. move the powersave logic up (only during
irq handling, tx path, submitting fw commands) but that's a bigger change and
can be implemented later.

Currently target to host (T2H) HTT messages are received at copy engine 1.
These messages are processed by HTC layer in both host and target.
To avoid HTC level processing overhead in both host and target,
the unused copy engine 5 is being used for receiving HTT T2H messages.
This will speedup the receive data processing as well as htt tx completion.
Hence host and target copy engine configuration tables are updated
to enable CE5 pipe. The in-direction HTT mapping is now pointing to CE5
for all HTT T2H.
Moreover HTT send completion messages are polled from HTC handler
as CE 4 is not interrupt-driven. For faster tx completion, CE4 polling
needs to be done whenever CE pipe which transports HTT Rx (target->host)
is processed. This avoids overhead of polling HTT messages from HTC
layer. Servicing CE 4 faster is helping to solve "failed to transmit
packet, dropping: -105".

Register receive callbacks for every copy engines (CE) separately
instead of having common receive handler. Some of the copy engines
receives different type of messages (i.e HTT/HTC/pktlog) from target.
Hence to service them accordingly, register per copy engine receive
callbacks.

The FreeBSD driver [0] uses the same 2G values as for the AR9280 chips.
Using the same values in ath9k results in much better throughput for me.
Before this patch I had a huge amount of packet loss (sometimes up to
40%) and the max transfer speed was somewhere around 5Mbit/s. With this
patch applied I have zero packet loss and ten times the throughput.
My device uses a AR9227 which is the PCI variant of the AR9287.

This patch reorders the call to the function ath10k_core_fetch_board_file
so that we have OTP binary before requesting for boardid-chipid. We get this
OTP data after parsing firmware-N.bin.

QCA6174 needs different board files based on board type. To make it easier to
distribute multiple board files and automatically choose correct board file
create a simple TLV file format following the same principles as with FW IEs.
The file is named board-2.bin and contain multiple board files. Each board file
then can have multiple names.
ath10k searches for file board-N.bin (where N is the interface version number
for the board file, just like we for firmware files) in /lib/firmware/*, for
example for qca99x0 it will try to find it here:
/lib/firmware/ath10k/QCA99X0/hw2.0/board-2.bin
If ath10k doesn't find board-2.bin then it will fallback to the old board.bin file.
This patch adds a simple name scheme using pci device id which for now will be
used by qca6174:
bus=%s,vendor=%04x,device=%04x,subsystem-vendor=%04x,subsystem-device=%04x
This removes the old method of having subsystem ids in ar->spec_board_id and
using that in the board file name.

Add the option to configure multiple 'scan plans' for scheduled scan.
Each 'scan plan' defines the number of scan cycles and the interval
between scans. The scan plans are executed in the order they were
configured. The last scan plan will always run infinitely and thus
defines only the interval between scans.
The maximum number of scan plans supported by the device and the
maximum number of iterations in a single scan plan are advertised
to userspace so it can configure the scan plans appropriately.
When scheduled scan results are received there is no way to know which
scan plan is being currently executed, so there is no way to know when
the next scan iteration will start. This is not a problem, however.
The scan start timestamp is only used for flushing old scan results,
and there is no difference between flushing all results received until
the end of the previous iteration or the start of the current one,
since no results will be received in between.
