Felix Fietkau 56bdbe0d6a ath9k: prevent early IRQs from accessing hardware

common->op_flags. Close a short time window between those two.

Felix Fietkau 9e4982f6a5 ath5k: fix hardware queue index assignment
Like with ath9k, ath5k queues also need to be ordered by priority.
queue_info->tqi_subtype already contains the correct index, so use it
instead of relying on the order of ath5k_hw_setup_tx_queue calls.

Felix Fietkau ad8fdccf9c ath9k_hw: fix hardware queue allocation
The driver passes the desired hardware queue index for a WMM data queue
in qinfo->tqi_subtype. This was ignored in ath9k_hw_setuptxqueue, which
instead relied on the order in which the function is called.

Stanislaw Gruszka dc50a52a36 Revert "rt2x00: Endless loop on hub port power down"
This reverts commit 2ad69ac597. It
causes wireless device disappear when we get -EPROTO error form USB
request. I encounter such situation occasionally when resume form
suspend with RT3070 adapter:

[  289.619985] ieee80211 phy0: rt2x00usb_vendor_request: Error - Vendor Request 0x06 failed for offset 0x0404 with error -71
[  289.639368] ieee80211 phy0: rt2800_wait_bbp_ready: Error - BBP register access failed, aborting
[  289.639374] ieee80211 phy0: rt2800usb_set_device_state: Error - Device failed to enter state 4 (-5)

Without the patch, except printing error, device works just fine after
resume.

Currently after timeouts and REGISTER_BUSY_COUNT tuning, we should
not have any "endless loop", though we can wait quite long when driver
is trying to communicate with the device through non functioning USB
connection. Generally the problem that commit 2ad69ac597 solves
is kinda artificial.

Stanislaw Gruszka 87dd2d76a9 rt2800: calculate tx power temperature compensation on selected chips
Currently implemented temperature compensation is only valid on some of
supported chips. Other chips do not need temperature compensation or
need different way to do this (not yet implemented in the rt2800
driver). Trying to do run rt2800_get_gain_calibration_delta() when this
is not appropriate on particular chip gives bogus result of TX power
and can make connection unstable.

This is follow up to commit 8c8d2017ba
"rt2800: fix RT5390 & RT3290 TX power settings regression". On that
commit we avoid setting BBP_R1 register, but the real problem is wrong
temperature compensation calculation.

Add mem_val debugfs file for dumping the firmware (target) memory and also for
writing to the memory. The firmware memory is accessed through one file which
uses position of the file as the firmware memory address. For example, with dd
use skip parameter for the address.

Beucase target memory width is 32 bits it's strongly recommended to use
blocksize divisable with 4 when using this interface. For example, when using
dd use bs=4 to set the block size to 4 and remember to divide both count and
skip values with four.

To read 4 kB chunk from address 0x400000:

dd if=mem_value bs=4 count=1024 skip=1048576 | xxd -g1

To write value 0x01020304 to address 0x400400:

echo 0x01020304 | xxd -r | dd of=mem_value bs=4 seek=1048832

To read 4 KB chunk of memory and then write back after edit:

dd if=mem_value of=tmp.bin bs=4 count=1024 skip=1048576
emacs tmp.bin
dd if=tmp.bin of=mem_value bs=4 count=1024 seek=1048576

Yanbo Li 077a380447 ath10k: add register access debugfs interface
Debugfs files reg_addr and reg_val are used for reading and writing to the
firmware (target) registers. reg_addr contains the address to be accessed,
which also needs to be set first, and reg_value is when used for reading and
writing the actual value in ASCII.

To read a value from the firmware register 0x100000:

# echo 0x100000 > reg_addr
# cat reg_value
0x00100000:0x000002d3

To write value 0x2400 to address 0x100000:

# echo 0x100000 > reg_addr

Sujith Manoharan 504f6cdf4a ath10k: fix shared WEP
When static keys are used in shared WEP, when a
station is associated, message 3 is sent with an
encrypted payload. But, for subsequent
authentications that are triggered without a
deauth, the auth frame is decrypted by the HW.

To handle this, check if the WEP keys have already
been set for the peer and if so, mark the
frame as decrypted. This scenario can happen
when a station changes its default TX key and initiates
a new authentication sequence.

In four of the rtlwifi drivers, the Makefile contains superfluous

regardless of the corresponding Kconfig option.

If the corresponding option is set to 'y', the build system will then
see the object file in obj-m and obj-y, which leads to a compilation
as a built-in only. Even though this leads to the desired behavior,
the unconditional appearance in obj-m is confusing for someone reading

Eyal Shapira 339b30864e iwlwifi: mvm: declare support for VHT BF info in radiotap
The driver knows whether an rx frame was beamformed and marks
it in the radiotap VHT flags. However it should also declare
that it knows to extract this info otherwise this gets discarded
by sniffers like Wireshark.

Luciano Coelho 2021a89d7b iwlwifi: mvm: treat netdetect wake up separately
When the device wakes up due to netdetect, we need to query different
things from the firmware than when it wakes up with a normal WoWLAN.
To make this easier, separate the netdetect wake up handling from the
rest.  For now, we don't send netdetect as a wake up reason, treating
it as a non-wireless wake up.

Luciano Coelho ec12f457d6 iwlwifi: mvm: refactor iwl_mvm_query_wakeup_reasons()
Refactor the iwl_mvm_query_wakeup_reasons() function to split the part
that gets the firmware status from the part that sets up the WoWLAN
status.  This will allow netdetect to reuse the code.

We need to send a WOWLAN_CONFIGURATION command also for netdetect and

the code that configures wowlan and netdetect when suspending and send
the WOWLAN_CONFIGURATION command also for net_detect.

Luciano Coelho 686e7fe1c4 iwlwifi: mvm: protect session during CSA
When another vif is also running during a channel switch, we need to
use a session protection when we move to the new channel, so that we
don't miss the beacons.  Without this, sometimes the other vif
repeatedly gets time exactly when we should be hearing the beacons,
preventing channel switch from completing.  Adding a session
protection that lasts from the moment the channel changes until 2
TBTTs later, ensures that we will hear the beacons on the destination
channel.

Luciano Coelho c6e0a3e044 iwlwifi: mvm: disable beacon filtering during CSA
After a channel switch, transmission on the new channel is only
started once we see a beacon on it.  Thus, beacon filtering needs to
be disabled during channel switch so that mac80211 receives this
beacon and finishes the process.
