34d4fcd881 ath9k: Read noise floor calibration data from eeprom
AR9003 devices can have calibrated noise floor values
which can be used instead of hard coded one. Read them
from eeprom and save interpolated value in nf limits for
the current channel.

528782ecf5 ath9k: Alternative EEPROM size for AR9003
AR9003 factory calibration allows to use bigger EEPROM than
standard 1k without changing the default layout. Allow
probing of EEPROM at alternative address if initial check
for default fails.
The original ar9003 eeprom ops are still be used.

81b35afa49 wil6210: support parsing brd file address from fw file
In order to allow using the same brd file across different
11ad chips, the address for loading the brd file should be
part of the FW file, instead of the brd file. The brd file is
expected to include only one section.
To allow backward compatibility the driver reads the
address from the brd file in case it is not included in the
FW file.

70bcc658c0 wil6210: fix random failure to bring network interface up
Currently when we want to bring the interface up, we first
reset the device which causes the boot loader to run. Then
we halt the device CPU, load FW image and resume the device
CPU.
There are some boot loader versions which perform redundant
memory accesses even when idle. Halting the device CPU
while boot loader access memory can cause the device memory
controller to get stuck, the FW will fail to load and the
network interface will not come up.
For such boot loaders implement a workaround where we freeze
the boot loader before halting the device CPU, so it will not
perform any memory accesses.

OTP HW vectors values are different for 40MHz and 330MHz AHB

In SW reset flow, the host driver sets the clock frequency
to 40MHz. In order to allow reading from the OTP, the host

a3fa3669d1 rtlwifi: Use mutex to replace spin_lock to protect IPS and LPS
Enter/leavel IPS and LPS are large critical section, and they can't use
sleep function because running in atomic-context, which own a spin_lock.
In commit ba9f93f82a ("rtlwifi: Fix enter/exit power_save"), it moves
LPS functions to thread-context, so this commit can simply change LPS's
spin lock to mutex.
Considering IPS functions, rtl_ips_nic_on() may be called by TX tasklet
(softirq-context) that check whether packet is auth frame. Fortunately,
current mac80211 will ask driver to leave IPS using op_config with
changed flag IEEE80211_CONF_CHANGE_IDLE, before issuing auth frame, so
IPS functions can run in thread-context and use mutex to protect critical
section, too.
Also, this commit removes some useless spin locks.

cc124d5cc8 brcmfmac: fix CLM load error for legacy chips when user helper is enabled
For legacy chips without CLM blob files, kernel with user helper function
returns -EAGAIN when we request_firmware(), and then driver got failed
when bringing up legacy chips. We expect the CLM blob file for legacy chip
is not existence in firmware path, but the -ENOENT error is transferred to
-EAGAIN in firmware_class.c with user helper.
Because of that, we continue with CLM data currently present in firmware
if getting error from doing request_firmware().

a64e7a79dd mwifiex: resolve reset vs. remove()/shutdown() deadlocks
Commit b014e96d1a ("PCI: Protect pci_error_handlers->reset_notify()
usage with device_lock()") resolves races between driver reset and
removal, but it introduces some new deadlock problems. If we see a
timeout while we've already started suspending, removing, or shutting
down the driver, we might see:

(a) a worker thread, running mwifiex_pcie_work() ->
    mwifiex_pcie_card_reset_work() -> pci_reset_function()
(b) a removal thread, running mwifiex_pcie_remove() ->
    mwifiex_free_adapter() -> mwifiex_unregister() ->
    mwifiex_cleanup_pcie() -> cancel_work_sync(&card->work)

Unfortunately, mwifiex_pcie_remove() already holds the device lock that
pci_reset_function() is now requesting, and so we see a deadlock.

It's necessary to cancel and synchronize our outstanding work before
tearing down the driver, so we can't have this work wait indefinitely
for the lock.

It's reasonable to only "try" to reset here, since this will mostly
happen for cases where it's already difficult to reset the firmware
anyway (e.g., while we're suspending or powering off the system). And if
reset *really* needs to happen, we can always try again later.

7e34c0d2f6 Revert "mwifiex: cancel pcie/sdio work in remove/shutdown handler"
This reverts commit b713bbf147.

The "fix" in question does not actually fix all related problems, and it
also introduces new deadlock possibilities. Since commit b014e96d1a
("PCI: Protect pci_error_handlers->reset_notify() usage with
device_lock()"), the race in question is actually resolved (PCIe reset
cannot happen at the same time as remove()). Instead, this "fix" just
introduces a deadlock where mwifiex_pcie_card_reset_work() is waiting on
device_lock, which is held by PCIe device remove(), which is waiting
on...mwifiex_pcie_card_reset_work().

The proper thing to do is just to fix the deadlock. Patch for this will
come separately.

====================
wireless-drivers-next patches for 4.16

Here are patches which have been accumulating over the holidays and
after the New Year. Business as usual and nothing special really
standing out.

But what's noteworthy here is that Larry Finger is stepping down as
the rtlwifi maintainer. He has been maintaining rtlwifi since it was
applied back in 2010 in commit 0c8173385e ("rtl8192ce: Add new
driver") and it has been no easy role trying to juggle between the
vendor, demanding upstream community and users. So big thank you to
Larry for all his efforts!

ath10k

* more preparation work for wcn3990 support

* add memory dump to firmware coredump files

wil6210

* support scheduled scan

* support 40-bit DMA addresses

qtnfmac

* support MAC address based access control

* support for radar detection and Channel Availibility Check (CAC)

mwifiex

* firmware coredump for usb devices

rtlwifi

* Larry Finger steps down as the maintainer and Ping-Ke Shih becomes
  the new maintainer

* add debugfs interfaces to dump register and btcoex status, and also
  write registers and h2c

51a1aaa631 mac80211_hwsim: validate number of different channels
When creating a new radio on the fly, hwsim allows this
to be done with an arbitrary number of channels, but
cfg80211 only supports a limited number of simultaneous
channels, leading to a warning.

Fix this by validating the number - this requires moving
the define for the maximum out to a visible header file.

b71d856ab5 mac80211_hwsim: add workqueue to wait for deferred radio deletion on mod unload
When closing multiple wmediumd instances with many radios and try to
unload the  mac80211_hwsim module, it may happen that the work items live
longer than the module. To wait especially for this deletion work items,
add a work queue, otherwise flush_scheduled_work would be necessary.

19d28fbd30 Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
BPF alignment tests got a conflict because the registers
are output as Rn_w instead of just Rn in net-next, and
in net a fixup for a testcase prohibits logical operations
on pointers before using them.

Also, we should attempt to patch BPF call args if JIT always on is
enabled.  Instead, if we fail to JIT the subprogs we should pass
an error back up and fail immediately.

b43_radio_2057_init_post is not called in an interrupt handler
nor holding a spinlock.
The function mdelay in it can be replaced with usleep_range,
to reduce busy wait.
