e065ddb891 mwifiex: fix SDIO firmware dump problem
It's been observed that firmware doesn't go back to normal
state when all firmware memories are dumped. As a result,
further commands are blocked. This happens due to missing
driver change of writing READ DONE to control register for
SDIO interface.

This patch adds a missing change to fix the problem.

fc23e81eb8 brcmfmac: allow NVRAM values to contain spaces
Platform NVRAMs often contain values with spaces. Even if right now most
firmware-supported entries are simple values, we shouldn't reject these
with spaces. It was semi-confirmed by Broadcom in the early patch adding
support for platform NVRAMs.

279b4cb7bc brcmfmac: treat \0 as end of comment when parsing NVRAM
This fixes brcmfmac dealing with NVRAM coming from platform e.g. from a
flash MTD partition. In such cases entries are separated by \0 instead
of \n which caused ignoring whole content after the first "comment".
While platform NVRAM doesn't usually contain comments, we switch to
COMMENT state after e.g. finding an unexpected char in key name.

c869f77d6a add mt7601u driver
Add support for the simplest of MediaTek Wi-Fi devices - MT7601U.
It is a single stream bgn chip with no bells or whistles.
This driver is partially based on Felix's mt76 but IMHO it doesn't
make sense to merge the two right now because MT7601U is a design
somewhere between old Ralink devices and new Mediatek chips.  There
wouldn't be all that much code sharing with the devices mt76 supports.
Situation may obviously change when someone decides to extend m76 with
support for the more recent USB dongles.

The driver supports only station mode.  I'm hoping to add AP support
when time allows.

This driver sat on GitHub for quite a while and got some testing there:

464a5f3f04 brcmfmac: Improve throughput by scheduling msbug flow worker.
The tx flow worker in msgbuf gets scheduled at tx till a certain
threshold has been reached. Then the tx completes will take over
the scheduling. When amsdu and ampdu is used the frames are
transferred wireless in a very bulky fashion, in combination
with this scheduling algorithm and buffer limiters in the stack
this can result in limited throughput. This change causes the
flow worker to be scheduled more frequently from tx.

1277fa2ab2 rtlwifi: Remove the clear interrupt routine from all drivers
Several of these drivers have there TX randomly blocked for 3~5 seconds while
measuring tx throughput (iperf). The root couse happens in rtl_pci_flush().
The function uses a while-loop to wait for TX queue length to decrease to 0.
The TX queue length counts the number of packets that are queued in the driver.
The driver relys on the TX OK interrupt to return skb and reduce TX queue length.

The interrupt subroutine disables interupts, reads the interrupt registers, and
then clears the registers in the beginning of _rtl_pci_interrupt(). After all
interupts process are finished, the driver invokes enable_interrupt() to enable
interupts. This behavior is normal for an interrupt subroutine.

But enable_interrupt() invokes clear_interrupt() again. This unexpected interrupt
clearing may cleari me fresh TX OK interrupts. These missing interrupts cause TX
queue length to never reduce to 0i, which causes rtl_pci_flush() to be stuck in
unterminated while-loop.

This patch removes clear_interrupt() in enable_interrupt() to avoid this behavior.

The problem is that test_bit() takes a bit number and not a mask.  It
means that when we do:

	set_bit(OP_TSF_RESET, &priv->op_flags);

Then it sets the (1 << 6) bit instead of the 6 bit so we are setting a
bit which is past the end of the unsigned long.

fe0a483ecf adm8211: fixed the possible pci cache line sizes inside switch-case
The PCI cache line size value was being compared against decimal values
prefixed with 0x.

Fixed the literals to use the correct hex values.

This has not been tested due to lack of hardware. However, the value in
`cline` is PCI cache line size, which is the CPU's cache line size.
It is less likely for cache line sizes to be 22 or 50, and more likely for
them to be 16 or 32. Also, as far as I understand, cache line size is used for
things like aligning DMA requests with CPU cache line, which improve
performance but wouldn't break anything if the value doesn't match. In
this case, we will fall through to the default case which leaves `reg`
unchanged.

48f4ca34f3 ath10k: add new 4addr related fw_feature
Some firmware revisions pad 4th hw address in
Native Wifi Rx decap. This is the case with 10.x
and it was assumed that this is true for all
firmware images.

However QCA988X with 999.999.0.636 and QCA61X4
with WLAN.RM.2.0-00088 don't have the padding.
Hence add a feature flag indicating that the
padding isn't present so firmware images can
advertise it appropriately. This way driver will
behave as it was before with old firmware blobs
and doesn't cause any regressions from user
perspective.

Effectively this patch enables QCA988X with
999.999.0.636 and QCA61X4 with WLAN.RM.2.0-00088
to set up client bridging provided user has an
updated firmware blob.

77258d409c ath10k: enable pci soc powersaving
By using SOC_WAKE register it is possible to bring
down power consumption of QCA61X4 from 36mA to
16mA when associated and idle.

Currently the sleep threshold/grace period is at a
very conservative value of 60ms.

Contrary to QCA61X4 the QCA988X firmware doesn't
have Rx/beacon filtering available for client mode
and SWBA events are used for beaconing in AP/IBSS
so the SoC needs to be woken up at least every
~100ms in most cases. This means that QCA988X
is at a disadvantage and the power consumption
won't drop as much as for QCA61X4.

Due to putting irq-safe spinlocks on every MMIO
read/write it is expected this can cause a little
performance regression on some systems. I haven't
done any thorough measurements but some of my
tests don't show any extreme degradation.

The patch removes some explicit pci_wake calls
that were added in 320e14b8db51aa ("ath10k: fix
some pci wake/sleep issues"). This is safe because
all MMIO accesses are now wrapped and the device
is woken up automatically if necessary.

917826be9f ath10k: fix idle power consumption
mac80211 can update vif powersave state while
disconnected. Firmware doesn't behave nicely and
consumes more power than necessary if PS is
disabled on a non-started vdev. Hence
force-enable PS for non-running vdevs.

This reduces power drain on QCA61X4 from 88mA to
36mA when interface is up and not associated.
QCA988X wasn't measured.

76d870ed09 ath10k: enable ASPM
It is actually safe to enable ASPM after the
device is booted up.

This reduces power drain of QCA61X4 when driver is
simply loaded (no interface is up) from 31mA to
14mA. QCA988X wasn't measured but doesn't seem to
regress in any other way.

b04096ff33 Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Four minor merge conflicts:

1) qca_spi.c renamed the local variable used for the SPI device
   from spi_device to spi, meanwhile the spi_set_drvdata() call
   got moved further up in the probe function.

2) Two changes were both adding new members to codel params
   structure, and thus we had overlapping changes to the
   initializer function.

3) 'net' was making a fix to sk_release_kernel() which is
   completely removed in 'net-next'.

4) In net_namespace.c, the rtnl_net_fill() call for GET operations
   had the command value fixed, meanwhile 'net-next' adjusted the
   argument signature a bit.

This also matches example merge resolutions posted by Stephen
Rothwell over the past two days.

184a394eea ath10k: increase relay buffer size of spectral scan
Spectral scan supported by ath10k has capability to monitor and report
through whole bands and channels, but current buffer size is too small
to save reported spectral scan data.
This results in dropping 5G channel reports at all when dual band card
is used, so that users are not able to analyze spectral environments.
Hence increase the buffer size to fix the problem.

A spectral data size is vary based on the number of bins, so the unit
buffer size, 1140, is chose to minimize relay buffer fragmentation.

The total buffer size is also chose in tradeoff with spectral scan
support vs. kernel memory consumption.
Since theoretical maximum buffer size, 9.5MB, can be consumed with
512 bins in dual bands, we target to cover up to 128 bins for all
channels in dual bands and due to the buffer size limitation,
spectral scan with bin number bigger than 128 needs to be run on
single band each.

a lot of small fixes and cleanups, the bigger items are:

  * mac80211 "fast-xmit", a mechanism to reduce, in most cases, the
    amount of code we execute while going from ndo_start_xmit() to

  * this also clears the way for properly supporting S/G and checksum
