[PATCH 1/2] ath10k: Support different txbf configuration schemes

qca61x4 uses the vdev param as a sole sufficient configuration
for txbf while qca99x0 enables txbf during peer assoc by
combining the vdev param value with peer assoc's vht capabilities

This patch gets the appropriate txbf configuration scheme
before passing the wmi command to enable the same in the firmware.

Release of RegMon - a fast in-kernel phy/mac dmonitoring tool for QCA/Atheros WiFi cards

Hi all,

Today I’ve released my WiFi register monitoring tool RegMon on GitHub: https://github.com/thuehn/RegMon


RegMon consists of Atheros driver patches to monitor arbitrary registers under ath9k, ath5k and madwifi
from user space with high sampling rates (up to ~20kHz). My common research use case is the fine-grained
monitoring and analysis of all busy states (tx, rx, energy detection & idle), TSF and noise floor of the
mac/phy layer from an Atheros WiFi card. But it can be used to sample any available register (like NAV,
error registers, ect.).
There are also a bunch of scripts in the repo to set-up a wireless experiment, collect RegMon traces, parse,
merge and plot them with R.

Feel free to use and change RegMon for your own purpose. As RegMon is still work in progress I am happy to
receive and include your feedback and ideas.

Greetings from Berlin
Thomas

[PATCH NEXT] rtlwifi: rtl8192c-common: Fix two typos

In this driver, two variables are masked by one quantity, and then tested
against a second number with more bits that the mask. Accordingly, the
test always fails. To minimize the possibility of such typos, a symbolic
definition of the mask is created and used.

The separate load and mask operations are also combined into a single
statement.

[PATCH NEXT 0/6] rtlwifi: Fix firmware header issues


While fixing an endian issue introduced in commit e996db69833a,
I realized that there were similar endian issues in several
of the drivers. In addition, these drivers were all defining a
similar struct. A single common definition is moved into the
main header, and all drivers are converted to use it. This
process exposed several endian issues that were not previously
detected by Sparse.

[PATCH NEXT 0/7] Make changes in rtlwifi and dependent drivers

The Realtek engineers have suggested several improvements to this family
of drivers. The changes include:

1. Fix the 5G channel assignments to remove unused channels.
2. Fix a potential race condition when updating CAM.
3. Change retry limits to depend on vif type.
4. Fix a race condition that could allow a change in the APOL key
   before packet 4 of the handshaking sequence has been transmitted.
   This problem affects rtl8192ee, rtl8723be, and rtl8821ae.

linux-4.2-rc5/drivers/net/wireless/rtlwifi/rtl8192c/dm_common.c: Bad test ?

[linux-4.2-rc5/drivers/net/wireless/rtlwifi/rtl8192c/dm_common.c:1545]: (style) Mismatching
assignment and comparison, comparison 'bt_pri==4294967295' is always false.

    bt_pri = bt_pri & 0x00ffffff;

   if (bt_tx == 0xffffffff && bt_pri == 0xffffffff &&

Six f in the first line, but eight in the second.

Would use of symbol constants help prevent this kind of problem occurring
in future ? 

Regards

Commit 1010ba4c5d1c ("ath10k: unregister and

instances of (futile) fragmentation threshold
configuration. No known firmware supports the
parameter so don't even bother setting it.
