Yan-Hsuan Chuang 3506bc286a rtlwifi: btcoex: 21a 2ant: action for wifi is idle/linking/common
Depending on the state of wifi, we need to set different tdma and coex
table parameters to make wfi and bt coexist smoothly. Otherwise the
bt may have low sound quality or mouse lag, which mean bad user
experience. The same problem may occur on wifi also, if could disconnect
or lose some important packets.

Yan-Hsuan Chuang 4da5e7ea13 rtlwifi: btcoex: 21a 1ant: avoid LPS/IPS mismatch for pnp notify
When driver is going to sleep, it does not leave LPS/IPS, thus the
BTCoex may have mismatch when driver wakes up. To avoid that, BTCoex
needs to clear the IPS/LPS state when it receives a pnp notify, then
it can properly set up the hw when driver wakes up.

Yan-Hsuan Chuang b01127b268 rtlwifi: btcoex: 23b 2ant: check PS state before setting tdma duration
For time division multiple access, the wifi and bt take turns to
transmit, but we need to let AP know that wifi is under standby mode by
sending null data to "pretend" entering power saving state using lps
rpwm.

But, the fw does not know if it is the actual power saving mode or just a
fake one to cheat to the AP. Hence, before fw setting the tdma duration,
the fw needs the driver to check the power saving state first.

Changes in the drivers for RTL8723BE and RTL8821AE require corresponding
changes in the firmware. This new firmware has been accepted into the
Linux firmware repo. To handle the case where the kernel has been

The code will attempt to read the new name, and fall back to the old one
if the new one is not available.

Nils Holland 3beb27028c rtl8187: Enable monitor mode to fix multicast reception
The rtl8187 cards don't seem to receive multicast frames, which,
among other things, makes them fail to receive RAs in IPv6 networks.
The cause seems to be that the RTL818X_RX_CONF_MULTICAST flag doesn't
have the desired effect.

Fix the issue by setting RTL818X_RX_CONF_MONITOR instead, which puts the
card into monitor mode and resolves the problem so that multicast frames
are sucessfully passed to the kernel.

The existence of the problem and the effectiveness of the solution has
originally been confirmed on an 8187B based card with the USB id of
0bda:8197. Subsequent testing by Larry Finger on an 8187L based card,
which follows the second (8187, i.e. "non-b") code path in the driver,
has confirmed that the fix does not cause any noticeable regresssions
there either.

Masahiro Yamada 550116d21a scripts/spelling.txt: add "aligment" pattern and fix typo instances
Fix typos and add the following to the scripts/spelling.txt:

  aligment||alignment

I did not touch the "N_BYTE_ALIGMENT" macro in
drivers/net/wireless/realtek/rtlwifi/wifi.h to avoid unpredictable
impact.

I fixed "_aligment_handler" in arch/openrisc/kernel/entry.S because
it is surrounded by #if 0 ... #endif.  It is surely safe and I
confirmed "_alignment_handler" is correct.

I also fixed the "controler" I found in the same hunk in
arch/openrisc/kernel/head.S.

Larry Finger d5efe1535a rtlwifi: Move items out of rtl_pci_priv and rtl_usb_priv
In commit 6773386f97 ("rtlwifi: rtl8192c-common: Fix "BUG: KASAN:"),
a BUG detected when CONFIG_KASAN=y was fixed by reordering the layouts
of struct rtl_pci_priv, and struct rtl_usb_priv so that the variables
used by both PCI and USB drivers have the same offsets in both structs.
The better fix of relocating the critical variables into struct rtl_priv
was deferred as these changes do not have to be applied to stable
kernels.

This change also removes CamelCase variables with pLed0 => pled0.

struct rtl_usb_priv, which is used by rtl8192cu. The problem was resolved
by placing the struct bt_coexist_info at the head of each of those private
areas.

Larry Finger 106e0deca1 rtlwifi: rtl8192cu: Convert driver to use common macros
These drivers use a set of complicated macros to extract and insert
information for the RX and TX descriptors. Driver rtl8192cu had a
different set than was used for the PCI-based drivers. To simplify
the code, rtl8192cu is switched to use the common version. In the
process, two errors in those common macros were found and fixed.

Besides simplifying the code, there is an additional benefit. We have
no BE hardware to test the PCI driver, but using the common macros
provides an additional test for the validity of many endian-sensitive
operations.

Larry Finger 69d8597e9f rtlwifi: rtl8192cu: Calculate descriptor checksum correctly for BE
This driver requires a checksum for the descriptors so that the wifi
chip is assured that the USB transmission was correct. These entries
are little-endian, but the driver was always using cpu order in the
calculation. As a result, the driver failed on BE hardware.

Larry Finger 89d32c9071 rtlwifi: Download firmware as bytes rather than as dwords
The firmware is read from disk as a little-endian byte string. The code
that loads the firmware into the device transfers it as 4-byte quantities.
The routines that write multi-byte quantities on BE hardware assume that
the data are in CPU order, and automatically do the conversion to the LE
order required by the device. As a result, the firmware is transmitted
incorrectly. Rather than do multiple byte swaps on the data, the download
routine is revised to transmit bytes rather than dwords. Although the
number of I/O operations is increased, the firmware is not often loaded.

All drivers have the same bug, and use essentially the same code to
download firmware. These routines have been moved into rtlwifi.

Some CamelCase variables have been renamed.

Larry Finger 9336d376ed rtlwifi: Remove debugging entry in sysfs
As the kernel provides access to module parameters through entries in
/sys/module/<driver>/parameters/, there is no need for a private
interface. Thus the existing code for setting the debug level is
removed.

Larry Finger c34df318ec rtlwifi: Convert COMP_XX entries into a proper debugging mask
The debugging macros contain a parameter COMP_XX that could be used as a
mask; however, the code turns all these various bits on at the same time.
This change implements them as a proper mask, and adds module parameters
to set the mask at load time.

The current name "debug" for the debug level has been changed to
"debug_level" to better differentiate it from "debug_mask".

The debug routines have also been changed to interrogate the structure
that is loaded at entry time. As a result, the structure rtl_debug is no
longer needed, and all references to it are deleted.

The most notable change here is the inclusion of airtime fairness
 scheduling to ath9k. It prevents slow clients from hogging all the
 airtime and unfairly slowing down faster clients.
 
 Otherwise smaller changes and cleanup.
 
 Major changes:
 
 ath9k
 
 * cleanup eeprom endian handling
 * add airtime fairness scheduling
 
 ath10k
 
 * fix issues for new QCA9377 firmware version
 * support dev_coredump() for firmware crash dump

Ping-Ke Shih 40b368af4b rtlwifi: Fix alignment issues
The addresses of Wlan NIC registers are natural alignment, but some
drivers have bugs. These are evident on platforms that need natural
alignment to access registers.  This change contains the following:
 1. Function _rtl8821ae_dbi_read() is used to read one byte from DBI,
    thus it should use rtl_read_byte().
 2. Register 0x4C7 of 8192ee is single byte.
