67a9566824 ath: Add regulatory mapping for Paraguya
The country code is used by the ath to detect the ISO 3166-1 alpha-2 name
and to select the correct conformance test limits (CTL) for a country. If
the country isn't available and it is still programmed in the EEPROM then
it will cause an error and stop the initialization with:

8800196824 brcmfmac: add debugfs entry for reading firmware capabilities
This allows reading all capabilities as reported by a firmware. They are
printed using native (raw) names, just like developers like it the most.
It's how firmware reports support for various features, e.g. supported
modes, supported standards, power saving details, max BSS-es.

Access to all that info is useful for trying new firmwares, comparing
them and debugging features AKA bugs.

66cffd6daa b43: fix transmit failure when VT is switched
Setup:
Using BCM4306 rev.03 chip based CardBus wireless card.
IRQ is shared with yenta (cardbus bridge) and i915 (display) driver.
For firmware, installed latest but dated openfwwf 5.2
(http://netweb.ing.unibs.it/~openfwwf/)

How-to-reproduce:
Do "ssh <NetBSD-remotehost>", then "ls -lR /" to generate traffic, then
repeatedly switch VTs by Alt-F1<>Alt-F2.
Eventually (within a minute) the card stops working.
You can receive traffic but no transmission.
For unknown reason it doesn't occur when just generating traffic by
"ssh <remotehost> ls -lR /".

With CONFIG_B43_DEBUG=y kernel config, when it stops,
the debug message shows
    kernel: b43-phy1 debug: Out of order TX status report on DMA ring 1. Expected 148, but got 180
The slot offset I observed so far was always 32.

When err_out2 is not set to make error messages successive,
the debug output will be like this:
kernel: b43-phy1 debug: Out of order TX status report on DMA ring 1. Expected 116, but got 148
kernel: b43-phy1 debug: Out of order TX status report on DMA ring 1. Expected 116, but got 150
kernel: b43-phy1 debug: Out of order TX status report on DMA ring 1. Expected 116, but got 120
kernel: b43-phy1 debug: Out of order TX status report on DMA ring 1. Expected 116, but got 152
kernel: b43-phy1 debug: Out of order TX status report on DMA ring 1. Expected 116, but got 122
kernel: b43-phy1 debug: Out of order TX status report on DMA ring 1. Expected 116, but got 154
kernel: b43-phy1 debug: Out of order TX status report on DMA ring 1. Expected 116, but got 124
kernel: b43-phy1 debug: Out of order TX status report on DMA ring 1. Expected 116, but got 156
kernel: b43-phy1 debug: Out of order TX status report on DMA ring 1. Expected 116, but got 126
The TX ring alternates between 2 sequences; the ring seems
to be completely confused. Controller restart is needed.

Workaround(1):
This problem doesn't occur when using propriatory firmware
you will extract by b43-fwcutter, so it may be a bug in
openfwwf firmware, as the comment in the b43_dma_handle_txstatus() suggests.
I wasn't able to find a bug in the terse openfwwf code though.

Workaround(2):
Using "pio=1" option to not use DMA makes this problem to
not occur.

Description of the patch:
This patch will forcibly reset the controller to make it
work again. Very kludgy and doesn't look right, but
the traffic will continue to flow.

e3148cc5fe ath10k: fix return value check in wake_tx_q op
ath10k_mac_tx_push_txq returns either a postive integer (length) on
success or a negative error code on error.

The "if (ret) break;" statement will thus always break out of the loop
immediately after ath10k_mac_tx_push_txq has returned (making the loop
pointless).

A side effect of this fix is that we will iterate the queue until
ath10k_mac_tx_push_txq returns -ENOENT. This will make sure the queue is
not added back to ar->txqs when it is empty. This could potentially
improve performance somewhat (I have seen a small improvement with SDIO
devices).

cfb353c0dc ath10k: add quiet mode support for QCA6174/QCA9377
To enable thermal throttling for QCA6174 and QCA9377,
implement gen_pdev_set_quiet_mode for them.
With this change, quiet period for QCA6174/QCA9377 can
be also set/get via debugfs.
Usage:
To set quiet period:
 echo <period> > /sys/kernel/debug/ieee80211/phyX/ath10k/quiet_period
To get the current quiet period:
 cat /sys/kernel/debug/ieee80211/phyX/ath10k/quiet_period

This change has been verified with
QCA6174 hw3.2(fw: WLAN_RM.4.4.1-00102-QCARMSWP-1).

4f9fb99001 mwifiex: increase TX threashold to avoid TX timeout during ED MAC test
While carrying energy detection(ED) tests, the chip will stop
transmission upon detecting an energy in the connected channel.
As a feedback, driver will stop dequeuing TX packets and due to
which wmm_tx_pending keep incremeting. Once wmm_tx_pending
reaches 100, driver calls netif_tx_stop_queue(). If TX ques is
not restarted within 5(watchdog_timeo) seconds, it will result in
TX timeout.

The ED test is carried out for one minute and the current
threshold of 100 is easily overcome by the traffic, cuasing TX
timeouts. To fix this increase the threshold to 400.

9c4a121e82 brcmfmac: Add support for bcm43364 wireless chipset
Add support for the BCM43364 chipset via an SDIO interface, as used in
e.g. the Murata 1FX module.

The BCM43364 uses the same firmware as the BCM43430 (which is already
included), the only difference is the omission of Bluetooth.

However, the SDIO_ID for the BCM43364 is 02D0:A9A4, giving it a MODALIAS
of sdio:c00v02D0dA9A4, which doesn't get recognised and hence doesn't
load the brcmfmac module. Adding the 'A9A4' ID in the appropriate place
triggers the brcmfmac driver to load, and then correctly use the
firmware file 'brcmfmac43430-sdio.bin'.
