Bruno Randolf c85ea1156d rtl8xxxu: Enable data frame reception in rtl8xxxu_start
mac80211 documentation says, the ieee80211_ops.start callback "must turn on
frame reception (for possibly enabled monitor interfaces.)". If not a single
monitor interface does not receive data frames.

Similarly we should not change the data reception based on the association
state.

Eliad Peller 1ad4f639cc iwlwifi: mvm: move TX PN assignment for TKIP to the driver
If protocol offloading is configured, the fw might generate some
frames (e.g. arp response) on its own during d3/d0i3.

On d3/d0i3 exit the driver queries the updated PN (if relevant),
and updates its keys (for the d0i3 case, this is done by
iwl_mvm_d0i3_exit_work(), which is scheduled on d0i3 exit)

While in d0i3, iwlmvm defers tx frames until d0i3 exit, and
then continues their processing.

This is problematic with TKIP, since the frame's PN has already
been set at this stage (in contrast to CCMP, where the PN is
being set only later on), so both the frame's PN and the upcoming
PN update (from d0i3 exit work) might be wrong.

Fix it by moving the TX PN assignment (for TKIP) to the driver,
similarly to CCMP.

Lior David 34d505193b cfg80211: basic support for PBSS network type
PBSS (Personal Basic Service Set) is a new BSS type for DMG
networks. It is similar to infrastructure BSS, having an AP-like
entity called PCP (PBSS Control Point), but it has few differences.
PBSS support is mandatory for 11ad devices.

Add support for PBSS by introducing a new PBSS flag attribute.
The PBSS flag is used in the START_AP command to request starting
a PCP instead of an AP, and in the CONNECT command to request
connecting to a PCP instead of an AP.

Emmanuel Grumbach a6bd005fe9 iwlwifi: pcie: fix RF-Kill vs. firmware load race
When we load the firmware, we hold trans_pcie->mutex to
avoid nested flows. We also rely on the ISR to wake up the
thread when the DMA has finished copying a chunk. During
this flow, we enable the RF-Kill interrupt.

The problem is that the RF-Kill interrupt handler can take
the mutex and bring the device down. This means that if
we load the firmware while the RF-Kill switch is enabled
(which will happen when we load the INIT firmware to read
the device's capabilities and register to mac80211), we
may get an RF-Kill interrupt immediately and the ISR will
be waiting for the mutex held by the thread that is
currently loading the firmware. At this stage, the ISR
won't be able to service the DMA's interrupt needed to
wake up the thread that load the firmware. We are in a
deadlock situation which ends when the thread that loads
the firmware fails on timeout and releases the mutex.

To fix this, take the mutex later in the flow, disable
the interrupts and synchronize_irq() to give a chance to
the RF-Kill interrupt to run and complete.
After that, mask all the interrupts besides the DMA
interrupt and proceed with firmware load. Make sure to
check that there was no RF-Kill interrupt when the
interrupts were disabled.

Luca Coelho 5e56276e75 iwlwifi: mvm: don't allow sched scans without matches to be started
The firmware can perform a scheduled scan with not matchsets passed,
but it can't send notification that results were found.  Since the
userspace then cannot know when we got new results and the firmware
wouldn't trigger a wake in case we are sleeping, it's better not to
allow scans without matchsets.

This patch adds an interface for handling commands like

powersave mode is quite bad, powersaving mode is unusable,

Sjoerd Simons 97f1a17109 brcmfmac: sdio: Increase the default timeouts a bit
On a Radxa Rock2 board with a Ampak AP6335 (Broadcom 4339 core) it seems
the card responds very quickly most of the time, unfortunately during
initialisation it sometimes seems to take just a bit over 2 seconds to
respond.

This results intialization failing with message like:
  brcmf_c_preinit_dcmds: Retreiving cur_etheraddr failed, -52
  brcmf_bus_start: failed: -52
  brcmf_sdio_firmware_callback: dongle is not responding

Increasing the timeout to allow for a bit more headroom allows the
card to initialize reliably.

A quick search online after diagnosing/fixing this showed that Google
has a similar patch in their ChromeOS tree, so this doesn't seem
specific to the board I'm using.

Rafał Miłecki d1e61b86a2 brcmfmac: treat NULL character in NVRAM as separator
Platform NVRAM (stored on a flash partition) has entries separated by a

simply consume it and analyze whatever is placed ahead.

This fixes harmless warnings spamming debugging output:

Rafał Miłecki a4f4abd037 brcmfmac: analyze descriptors of current component only
So far we were looking for address descriptors without a check for
crossing current component border. In case of dealing with unsupported
descriptor or descriptor missing at all the code would incorrectly get
data from another component.

Consider this binary-described component from BCM4366 EROM:
4bf83b01	TAG==CI		CID==0x83b
20080201	TAG==CI		PORTS==0+1	WRAPPERS==0+1
18400035	TAG==ADDR	SZ_SZD		TYPE_SLAVE
00050000
18107085	TAG==ADDR	SZ_4K		TYPE_SWRAP

Driver was assigning invalid base address to this core:
brcmfmac:  [6 ] core 0x83b:32 base 0x18109000 wrap 0x18107000
which came from totally different component defined in EROM:
43b36701	TAG==CI		CID==0x367
00000201	TAG==CI		PORTS==0+1	WRAPPERS==0+0
18109005	TAG==ADDR	SZ_4K		TYPE_SLAVE

This change will also allow us to support components without wrapper
address in the future.

First of all it changes the way we calculate primary channel offset. If
we use e.g. 80 MHz channel with primary frequency 5180 MHz (which means
center frequency is 5210 MHz) it makes sense to calculate primary offset
as -30 MHz.
Then it fixes values we compare primary_offset with. We were comparing
offset in MHz against -2 or 2 which was resulting in picking a wrong
primary channel.

Maya Erez fe5c271e28 wil6210: protect synchronous wmi commands handling
In case there are multiple WMI commands with the same reply_id,
the following scenario can occur:
- Driver sends the first command to the device
- The reply didn’t get on time and there is timeout
- Reply_id, reply_buf and reply_size are set to 0
- Driver sends second wmi command with the same reply_id as the first
- Driver sets wil->reply_id
- Reply for the first wmi command arrives and handled by wmi_recv_cmd
- As its ID fits the reply_id but the reply_buf is not set yet it is
handled as a reply with event handler, and WARN_ON is printed

This patch guarantee atomic setting of all the reply variables and
prevents the above scenario.

When in AP mode we need to filter in beacons from other APs to update HT
operation mode. As a power optimization the beacons are filtered out when
there are no associated stations. As a result, when there are no

station connects.

The 9000 series introduces several changes in the device
DMA operation.
As the device now supports multi-queue rx, several DMA channels
should be configured.
The flows of providing the device with the allocated RBDs now
changes as well - the device maintains a separate table of used
and free table.

The hardware may use the free table to feed RBDs to any queue.
This requires maintaing a shared table to map returned RBDs to
the original RXB - for that purpose the VID is introduced - an
internal identifier of the RB placed in the lower 12 bits and
returned by HW in the used data.

Another change is the support of 64 bit DMA address.

The 9000 series devices will support multi rx queues.
Current code has one static rx queue - change it to allocate
a number of queues per the device capability (pre-9000 devices

Subsequent generalizations are:

Change the code to access an explicit numbered rx queue only
when the queue number is known - when handling interrupt, when
accessing the default queue and when iterating the queues.
The rest of the functions will receive the rx queue as a pointer.

Generalize the warning in allocation failure to consider the
allocator status instead of a single rx queue status.

Move the rx initial pool of memory buffers to be shared among
all the queues and allocated to the default queue on init.

Emmanuel Grumbach 3955525d5d iwlwifi: pcie: buffer packets to avoid overflowing Tx queues
When the Tx queues are full above a threshold, we
immediately stop the mac80211's queue to stop getting new
packets. This worked until TSO was enabled.
With TSO, one single packet from mac80211 can use many
descriptors since a large send needs to be split into
several segments.
This means that stopping mac80211's queues is not enough
and we also need to ensure that we don't overflow the Tx
queues with one single packet from mac80211.
Add code to transport layer to do just that. Stop
mac80211's queue as soon as the queue is full above the
same threshold as before, and keep pushing the current
packet along with its segments on the queue, but check
that we don't overflow. If that would happen, buffer the
segments, and send them when there is room in the Tx queue
again. Of course, we first need to send the buffered
segments and only then, wake up mac80211's queues.

Shengzhen Li dc896b15fe mwifiex: fix power state out of sync problem
It's been observed that driver's power state goes out
of sync with firmware in some corner cases. When this
happens, driver tries to download the data to firmware
assuming it's awake which causes Tx data timeout.

Main thread will process interrupt as soon as interrupt
handler fills 'int_status' variable.

This patch fixes the race issue by updating 'int_status'
at the end of mwifiex_interrupt_status().

chunfan chen 2fd5c6ed0b mwifiex: firmware download enhancements
Same chip is being used by WLAN as well as bluetooth
drivers. Each driver needs to check during initialisation
if firmware is already active or it needs to be freshly
downloaded. If one driver has started downloading the
firmware, other finds the winner flag as false.

mwifiex_check_fw_status() checks firmware status and also
check if WLAN is the winner for firmware downloading.

Once we detect that other interface is downloading
the firmware, we call this routine again with max
poll count to wait until firmware is ready.

This patch splits the routine to avoid checking
winner status unnecessarily multiple times and ensures
that correct messages are displayed to user.

Firmware status poll count is also increased to 150.

Raja Mani 0b523ced9a ath10k: add basic skeleton to support ahb
qca4019 uses ahb instead of pci where it slightly differs in device
enumeration, clock control, reset control, etc. Good thing is that
ahb also uses copy engine for the data transaction. So, the most of
the stuff implemented in pci.c/ce.c are reusable in ahb case too.

Device enumeration in ahb case comes through platform driver/device
model. All resource details like irq, memory map, clocks, etc for
qca4019 can be fetched from of_node of platform device.

Simply flow would look like,

 device tree => platform device (kernel) => platform driver (ath10k)

Device tree entry will have all qca4019 resource details and the same
info will be passed to kernel. Kernel will prepare new platform device
for that entry and expose DT info to of_node in platform device.
Later, ath10k would register platform driver with unique compatible name
and then kernels binds to corresponding compatible entry & calls ath10k
ahb probe functions. From there onwards, ath10k will take control of it
and move forward.

New bool flag CONFIG_ATH10K_AHB is added in Kconfig to conditionally
enable ahb support in ath10k. On enabling this flag, ath10k_pci.ko
will have ahb support. This patch adds only basic skeleton and few
macros to support ahb in the context of qca4019.

Raja Mani 4ddb3299aa ath10k: make ath10k_pci_read32/write32() ops more generic
ath10k_pci_read32/write32() does work more specific to
PCI by ensuring pci wake/sleep for every read and write.
There is a plan to use most of stuff available in pci.c
(irq stuff, copy engine, etc) for AHB case. Such kind
of pci wake/sleep for every read/write is not required
in AHB case (qca4019). All those reusable areas in pci.c
and ce.c calls ath10k_pci_read32/write32() for low level
read and write.

In fact, ath10k_pci_read32/write32() should do what it does
today for PCI case. But for AHB, it has to do differently.
To make ath10k_pci_read32/write32() more generic, new function
pointers are added in ar_pci for the function which does
operation more close to the bus. Later, corresponding bus
specific read and write function will be mapped to that.

ath10k_pci_read32/write32() are changed to call directly
those function pointers without worrying which bus underlying
to it. Also, the function to get number of bank is changed
in the same way.

Miaoqing Pan 466b0f0208 ath9k: fix data bus error on ar9300 and ar9580
One crash issue be found on ar9300: RTC_RC reg read leads crash, leading
the data bus error, due to RTC_RC reg write not happen properly.

Warm Reset trigger in continuous beacon stuck for one of the customer for
other chip, noticed the MAC was stuck in RTC reset. After analysis noticed
DMA did not complete when RTC was put in reset.

So, before resetting the MAC need to make sure there are no pending DMA
transactions because this reset does not reset all parts of the chip.

The 12th and 11th bit of MAC _DMA_CFG register used to do that.
	12 cfg_halt_ack 0x0
		0 DMA has not yet halted
		1 DMA has halted
	11 cfg_halt_req 0x0
		0 DMA logic operates normally
		1 Request DMA logic to stop so software can reset the MAC

The Bit [12] of this register indicates when the halt has taken effect or
not. the DMA halt IS NOT recoverable; once software sets bit [11] to
request a DMA halt, software must wait for bit [12] to be set and reset
the MAC.

So, the same thing we implemented for ar9580 chip.
