Due to mac80211 triggering the hardware to enter idle mode, it fails
to install WEP key causing connected station can't ping successfully.
Currently, it forces the hardware to leave idle mode before driver
adding WEP keys.

To support 36-bit DMA, configure chip proprietary bit via PCI config API
or chip DBI interface. However, the PCI device mmap isn't set yet and
the DBI is also inaccessible via mmap, so only if the bit can be accessible
via PCI config API, chip can support 36-bit DMA. Otherwise, fallback to
32-bit DMA.
With NULL mmap address, kernel throws trace:

Add an dbgfs mlo_mode to get/set MLO mode. And, support to trigger MLSR
switching. Setting it will automatically disable MLO Dynamic Mechanism
(DM). Then MLO things can follow commands via dbgfs mlo_mode instead of
MLO DM. The disabled DM(s) can be checked/cleared via dbgfs disable_dm.
The following is an use example.
Read it to show current MLD status.
$ cat mlo_mode
MLD(s) status: (MLO DM: enable)
#0: MLO mode 0, valid 0x6, active 0x2
Write it to switch to MLSR on link id 2.
$ echo 0 2 > mlo_mode
$ cat mlo_mode
MLD(s) status: (MLO DM: disable)
#0: MLO mode 0, valid 0x6, active 0x4
Besides, to be safer, add RWLOCK attribute to dbgfs disable_dm.

Add MLSR switch mechanism based on tracking RSSI. Switch to a 2 GHz link
(if any) when average RSSI is lower than threshold -53. And, switch out
from a 2 GHz link when average RSSI is larger than threshold -38.
The sequence of MLSR switch handling is like the following.
1. initialize target link and configure to PS mode
2. configure current designated link to PS mode
3. configure target link to non-PS mode
4. deinitialize currently active links except target link
The above flow also implies that target link becomes new designated link.

Wi-Fi 7 chips have dual HW bands. After impending MLO support, they
can work with HW-[0] / HW-[1] / HW-[0,1] according to active links.
So, during setting channel, also re-calculate the MLO DBCC mode flag.
Then, leaf chip functions of setting channel can configure with HWs
based on current case.
Besides, tweak the initial and idle MLO DBCC mode of Wi-Fi 7 chips to
MLO_1_PLUS_1_1RF to work with dual HW bands. And, after disconnecting,
due to no active links, MLO DBCC mode will re-calculate to idle case,
i.e. MLO_1_PLUS_1_1RF.

Some users have RTL8723DS chips with nearly blank efuse. Currently these
chips cannot connect when using rtw88, but they do work using the old
out-of-tree driver.
Use reasonable default values for TX power, antenna configuration, and
crystal cap if the chip's efuse is missing these things.
RTL8723D can use the same default values as RTL8703B, so simply move
the code from rtl8703b_read_efuse() to the shared function
__rtl8723x_read_efuse().

A link bound to HW band 0 was previously always assumed to exist, because
it's true on non-MLD connection, and MLO connection is not supported yet.
Now, start to consider MLO cases and prepare to enable MLO support in the
following. Add skeleton of designated link. For single-link cases, helper
returns the one. For multi-link cases, priorities can be scheduled. Then,
drop assumption of link bound to HW band 0.
One exception is that MCC doesn't work with MLD yet, so it still expects
link on HW band 0 somewhere.

Originally, a macro, RTW89_ROC_BY_LINK_INDEX, is used to decide the link
which deals with the ROC process. Before enabling MLO support, it's fine
to hard-code RTW89_ROC_BY_LINK_INDEX as 0 since the link instance-0 (on
HW-0) is always active. But, for the impending enablement of MLO support,
tweak the leaf functions to dynamically handle ROC link instance index.
Besides, in the follow-up, ROC caller will get a designated link and will
then drop RTW89_ROC_BY_LINK_INDEX.

In preparation for making the kmalloc family of allocators type aware,
we need to make sure that the returned type from the allocation matches
the type of the variable being assigned. (Before, the allocator would
always return "void *", which can be implicitly cast to any pointer type.)
The assigned type is "struct rtw89_reg2_def *" but the returned type,
while technically matching, will be const qualified. As there isn't a
general way to discard "const" qualifiers, adjust the returned type to
match the assigned type. No change in allocation size results.

RTL8723BE found on some ASUSTek laptops, such as F441U and X555UQ with
subsystem ID 11ad:1723 are known to output large amounts of PCIe AER
errors during and after boot up, causing heavy lags and at times lock-ups:
pcieport 0000:00:1c.5: AER: Correctable error message received from 0000:00:1c.5
pcieport 0000:00:1c.5: PCIe Bus Error: severity=Correctable, type=Physical Layer, (Receiver ID)
pcieport 0000:00:1c.5: device [8086:9d15] error status/mask=00000001/00002000
pcieport 0000:00:1c.5: [ 0] RxErr
Disable ASPM on this combo as a quirk.
This patch is a revision of a previous patch (linked below) which
attempted to disable ASPM for RTL8723BE on all Intel Skylake and Kaby Lake
PCIe bridges. I take a more conservative approach as all known reports
point to ASUSTek laptops of these two generations with this particular
wireless card.
Please note, however, before the rtl8723be finishes probing, the AER
errors remained. After the module finishes probing, all AER errors would
indeed be eliminated, along with heavy lags, poor network throughput,
and/or occasional lock-ups.

If toa-aux is negative, TBTT-aux would in logic fall into duration-ref.
Then, if auxiliary role is GO unfortunately, it cannot guarantee that
beacons will TX well. So now, when deciding the lower bound of toa-ref,
take toa-aux into account. Make toa-aux at least be zero in normal cases.

Since tob (time offset behind) could be negative, change the type of tob in
microsecond to s32. And, refine accumulation with while-loop by calculation
with roundup_u64(). Besides, as long as one of the MCC roles is GO, use the
short MCC start time.

MCC has a courtesy mechanism which allows one role to use another's
duration in a given cycle. Originally, this courtesy mechanism only
supports in one direction. However, in some field cases, both of MCC
roles may simultaneously have timing configurations that are not good
enough. So, support courtesy mechanism in both directions.

MCC has a courtesy mechanism which allows one role to use another's
duration in a given cycle. Courtesy mechanism will be enabled when
one role has a not perfect duration. Otherwise, not. When MCC updates,
duration of each role will be re-calculated. And then, the new courtesy
config might be different from the old one. However, to change courtesy
config, the entire MCC plan requires to be renewed when MCC updates.

MCC will limit the time a role can use in a schedule according to the
periodic NoA. Original logic didn't consider the case where NoA start
time has passed. It might lead to inaccurate result. So, tweak it.

There are two roles during MCC and the offset between their TBTT is called
beacon offset. Originally, when MCC runs GO+STA mode, it used fixed beacon
offset to simplify some logic because GO role can master its TSF. However,
if MCC is stopped and restarted before a same GO is down, its TSF might be
discontinuous. Then, there might be undefined behavior happens in GC sides.
So, to let a same GO have a continuous TSF, MCC no longer changes its TSF
to meet a fixed beacon offset. Instead, GO+STA mode also calculates beacon
offset dynamically as what GC+STA mode did.

When APs or GOs are up, their TSF start point are randomized to avoid
collisions. However, the TSF of an existing AP/GO would be randomized
multiple times. It caused the TSF is discontinuous to the corresponding
STA/GC sides. So, once TSF has been randomized, don't re-randomize it
unless SER (system error recovery) happens unfortunately.

Since FW cannot handle HW scan process and MCC (multi-channel concurrency)
mode simultaneously, if a HW scan is requested during MCC, MCC mode will be
paused temporarily. Then, the GO role if any might be absent. So, calculate
an estimated time for the requested HW scan process and search for existing
GO roles to fill one-time NoA.

FW has a limited amount of channels that can be dealt with by one HW scan
H2C command. Based on the limit, channels in scan request might be parsed
into SW structure piece by piece along with multiple HW scan H2C commands.
But, in order to estimate things of entire HW scan process, it's required
to have the whole parsed channel list when HW scan is going to start. So,
tweak HW scan flow to prepare the whole channel list ahead. Still, each HW
scan H2C command takes allowed amount of channels from the list according
to the limit.

These stuffs have no suffix, but not universal, and only work for Wi-Fi 6.
Since the corresponding HW scan struct/func of Wi-Fi 7 have suffix "_be",
to avoid misunderstanding and improve readability, also add suffix "_ax"
to these Wi-Fi 6 stuffs.
(No logic is changed.)

Before adopting regd_UK TX power settings, some certifications are needed
and might be platform-level. Without that, should adopt regd_ETSI TX power
settings. But for now, there is no way to inform driver of it yet. So, add
a flag first. But for now, comprehensively use regd_ETSI TX power settings
to restrict regd_UK.
Plan to define an ACPI DSM function to inform driver whether to use regd_UK
own TX power settings or not afterwards.
