clang warns (or errors with CONFIG_WERROR=y):
drivers/net/wireless/realtek/rtw89/sar.c:216:3: error: unannotated fall-through between switch labels [-Werror,-Wimplicit-fallthrough]

Clang is a little more pedantic than GCC, which does not warn when
falling through to a case that is just break or return. Clang's version
is more in line with the kernel's own stance in deprecated.rst, which
states that all switch/case blocks must end in either break,
fallthrough, continue, goto, or return. Add the missing break to silence
the warning.

The ENV_MNTR(environment monitor) is the dynamic mechanism which based on
the HW of CCX(Cisco Compatible Extensions) which provide the channel
loading and noisy level indicator to debug or support the 802.11k. The
PHYSTS provide the detail PHY information per packet we received for
debugging. The DIG(dynamic initial gain) is the dynamic mechanism to
adjust the packet detect power level by received signal strength to avoid
false detection of the WiFi packet.
The address of registers used for ENV_MNTR, PHYSTS and DIG of WiFi 7 IC
are different with WiFi 6 series, so we modify the method to access the
register address in order to compatible with all WiFi 7 and 6 ICs.

cr_base is base address of PHY control register. The base of WiFi 6 and 7
chips are 0x1_0000 and 0x2_0000 respectively, so define them accordingly.
For example, if PHY address is 0x1330, absolute address is 0x1_1330 for
WiFi 6 chips, and 0x2_1330 for WiFi 7 chips.
Meanwhile, there are two copies of PHY hardware named PHY0 and PHY1. The
offset between them is 0x2_0000, so the base address of PHY0 and PHY1 are
0x2_0000 and 0x4_0000 respectively.

To diagnose abnormal behavior, we need to dump certain internal memory.
For example, dump security CAM when debugging encryption/decryption
problems, or dump BA CAM when debugging abnormal BlockAck.
Since the indirect address and internal memory base address are different
between WiFi 6 and 7 chips, add fields to reuse codes.
Also, only WiFi 6 chips initialize DMAC and CMAC tables via this indirect
interface, so no need to change the constant register address, and
new firmware will help to initialize these tables.

There are two copies of MAC hardware called band0 and band1. Basically,
the only difference between them is base address, so we can share functions
with a 'band' (or 'mac_idx') argument.
The offset of base address of WiFi 6 and 7 are 0x2000 and 0x4000
respectively, so add band1_offset field to new introduced struct
mac_gen_def to possibly reuse functions.

We prepare to deal with multiple channels via new entity modes.
* MCC_PREPARE: Transitional mode before MCC
* MCC: Multi-Channel Concurrent mode
And, enum of sub-entity is extended for second channel context.
We add the entry flow of multi-channel handling and the core stuffs
for extended index of sub-entity. And, we now deal with the filling
of entity channels' info in entity recalc where we know the number
of active chanctx. However, the other detail coding of MCC start/stop
will be implemented in the following.
Besides, chanctx listener struct is pre-added in chip info. Each
component can add callback type in chanctx listener and configure
its callback function to react according to chanctx states. We know
at least RFK (RF calibration) and BTC (BT coexistence) will require
such callbacks.

Callers call renew function when wanting to generate a new P2P NoA
information element, and call append function to append NoA attribute
one by one. Then, updating beacon work will fetch the P2P NoA information
element configured by callers and add it to beacon.
The use case of MCC (multi-channel concurrent) <GO + STA> for example:
* start MCC - GO part
renew P2P NoA
append period NoA after calculation
* download beacon for GO
fetch P2P NoA and add to beacon content
* stop MCC - GO part
renew P2P NoA (reset)

The difference between rtw89_hw_to_nl80211_band() and the original raw
judgement is the case on 6 GHz. Since rtw89_correct_cck_chan() is common
code independent on chip, if runtime chip doesn't support 6 GHz, it is

A mouse that uses a USB connection is called a "USB mouse" device (or
"USB mouse" for short), not a "mouse USB" device. By analogy, a WiFi
adapter that connects to the host computer via USB is a "USB wireless"
device, not a "wireless USB" device. (The latter term more properly
refers to a defunct Wireless USB specification, which described a
technology for sending USB protocol messages over an ultra wideband
radio link.)
Similarly for a WiFi adapter card that plugs into a PCIe slot: It is a
"PCIe wireless" device, not a "wireless PCIe" device.

Time Averaged SAR (TAS) tracks the amount of transmit power over a
period of time and adjusts the power accordingly. Two thresholds are
used to determine when to increase or reduce transmit power: Dynamic
Power Reduction (DPR) on/off. Compared to Static SAR, which has a
constant transmit power, TAS can improve the user experience or
range extension.
TAS can be enabled through BIOS, and the driver will evaluate
Realtek ACPI DSM with RTW89_ACPI_DSM_FUNC_TAS_EN to determine
whether TAS should be enabled.

WiFi 7 chips doesn't have static const tables defined in driver. If tables
aren't loaded properly from firmware file, driver can get NULL pointer
access exception. One way is to add the checking statements when trying to
access these tables, but I choose to check them right after loading
firmware elements from firmware file, so I don't need to add error handlers
everywhere.
Currently, the needed firmware elements of WiFi 6 chips are all zero, and
coming WiFi 7 chip will need at least BB MCU, parameters of BB and RF.
We will add them after 8922AE is verified.

We use tables defined in firmware elements with higher priority than
original static const tables defined in driver, because WiFi 7 chips will
not define the tables in driver, and existing chips can possibly migrate to

In order to pack more data into firmware file, we introduce firmware
elements and append BB_MCU firmware first. The first part of new firmware
file is still unchanged firmware of WiFi CPU, so the new firmware format
can be backward compatible to old format. The new elements part consists
of ID and size basically, which can append more elements simply. To avoid
unaligned access in certain platform and be easy to read, headers of all
elements start at 16-byte aligned address.

A firmware with v1 format contains many sections to download. Add parser to
read section type, target address, length, checksum and so on, and then
download the section to WiFi CPU with proper location.
The additional dynamic header length named dynamic_hdr_len is used to
skip content of dynamic header containing compiler flags of firmware, which
can help to determine variant firmware build, but currently rtw89 only
use single one variant. So, just skip the content.
The layout of a WiFi CPU firmware with v1 format looks like:

Firmware C2H events contain two-word header which can indicate category,
class, function and length of received events. Use struct to access them,
and doesn't change logic at all.

H2C RA V1 command adds two words to support WiFi 7 chips, which can
possibly support up to 4SS rates. Because current chips have only 2SS
rates, leave the fields blank for now. The main changes are to set
extended bits of EHT mode and bandwidth -- add a bit for EHT mode; add a
bit to enumerate 320MHz channel bandwidth.

RA (rate adaptive) H2C command is used to tell firmware which rates can
be used for specified MAC ID. Basically, this commit doesn't change result.
Only change to set two 32-bit instead of continual 8-byte rate masks one
by one. Originally, we only set 5-byte masks, because existing WiFi 6
2SS chips only need 5-byte masks. Setting two 32-bit masks will be more
efficient and also can support coming WiFi 7 2SS chips containing more
rates.

To support EHT rate, hardware rate v1 is introduced. The CCK and OFDM rates
are persistent. HT/VHT/HE rates use different rate code from original, and
add new code for EHT rates.

When using compressed firmware, the early firmware load feature will fail.
In most cases, the only downside is that if a device has more than one
firmware version available, only the last one listed will be loaded.
In at least two cases, there is no firmware loaded, and the device fails
initialization. See https://github.com/lwfinger/rtw89/issues/259 and
https://bugzilla.opensuse.org/show_bug.cgi?id=1212808 for examples of
the failure.
When firmware_class.dyndbg=+p" added to the kernel boot parameters, the
following is found:

If there is a failure during kstrtobool_from_user()
rtw89_debug_priv_btc_manual_set should return a negative error code
instead of returning the count directly.
Fix this bug by returning an error code instead of a count after
a failed call of the function "kstrtobool_from_user". Moreover
I omitted the label "out" with this source code correction.

The main change is to adjust RX calibration groups from {0,1,2,3} to {0,2}
in 5 GHz, so reduce elements from 4 to 2, and use index to iterate them.
Meanwhile, always do RX narrowband calibration (ID_NBRXK) for each group.
NCTL is used to assist IQK, so also update NCTL to 0x6 along with internal
