f9fe3baeb2 wifi: rtw89: fw: move v1 MSSC out of __parse_security_section() to share with v0
The security section can be a common parser for v0 and v1 format of
firmware header, so move retrieval code of v1 MSSC from the function, and
then sharing becomes possible.

Not logic change at all.

The secure key used by certain hardware module is programmed in efuse, so

WiFi 6 chips.

f9e0189cbc wifi: rtw88: 8812a: Mitigate beacon loss
The RTL8812AU has a reception problem, maybe only in the 5 GHz band.
Sometimes, in some positions, it stops receiving anything even though
the distance to the AP is only ~3 meters and there are no obstacles.
Moving it a few centimeters fixes it.

Switch the initial gain to maximum coverage when there is beacon loss.
This only helps sometimes. This is similar to what the official driver
does.

bfcee5ee92 wifi: rtw88: 8821a: Regularly ask for BT info updates
The RTL8821AU firmware sends C2H_BT_INFO by itself when bluetooth
headphones are connected, but not when they are disconnected. This leads
to the coexistence code still using the A2DP algorithm long after the
headphones are disconnected, which means the wifi speeds are much lower
than they should be. Work around this by asking for updates every two
seconds if the chip is RTL8821AU.

b19840afc0 wifi: rtw88: coex: Support chips without a scoreboard
All the chips currently supported have a "scoreboard": the chip keeps
track of certain things related to bluetooth, for example, whether
bluetooth is active. The information can be read from register 0xaa.

RTL8821AU doesn't have this. Implement bluetooth activity detection in
rtw_coex_monitor_bt_enable() based on the bluetooth TX/RX counters.

This is mostly important for RTL8811AU, the version of RTL8821AU without
bluetooth. Without this change, the driver thinks bluetooth is active
and the wifi speeds are low.

57289d30cd wifi: rtw88: Detect beacon loss with chips other than 8822c
The driver is supposed to avoid entering LPS (power saving) when there
is beacon loss, but only RTL8822C detects the beacon loss (because it
has beacon filtering in the firmware).

Detect beacon loss with the other chips by checking if we received less
than half the expected number of beacons in the last 2-second interval.

This gets rid of the occasional "failed to get tx report from firmware"
warnings with RTL8821AU. It may also avoid some disconnections.

82a617413e wifi: rtw88: Support TX page sizes bigger than 128
All the chips supported so far have a TX page size of 128 bytes.

Change the type of the page_size member of struct rtw_chip_info from u8

RTL8812AU (page size of 512 bytes). Also change the types of several
related variables and function parameters from u8 to u16.

The TX page size is used, among other things, to construct the beacon,
null data, QOS null data, and PS poll templates which are uploaded to
the chip's reserved page. Each template needs to be aligned on a
multiple of the TX page size. Power saving can't work if the TX page
size is wrong.

c7706b1173 wifi: rtw88: Enable data rate fallback for older chips
RTL8811AU fails to perform the 4-way handshake when the AP is too far
because it transmits the EAPOL frames at MCS9 and when that doesn't
work it retries 48 times with the same rate, to no avail.

Retrying 48 times with the same rate seems pointless. Set the
appropriate field in the TX descriptor to allow it to use lower rates
when retrying.

Set it for RTL8723D and RTL8703B because they interpret this field the
same way as RTL8811A.

The newer RTL8822C, RTL8822B, RTL8821C seem to interpret this field in
the TX descriptor differently, so leave it alone for those chips.

Tested with RTL8811AU and RTL8723DU.

2305ebc183 wifi: rtw89: tweak setting of channel and TX power for MLO
Setting of channel and TX power depend on channel contexts, but original
code cannot handle combination of MCC (multi-channel concurrency) and MLO
well. So according to active interfaces, we generate a table for current
channel contexts. And then based on entity mode, we get the corresponding
channel context to apply during channel or TX power setting. When MLO is
supported, there will be dual-PHY and we will apply the channel context of
the 2nd link to the 2nd PHY.

68ec751b28 wifi: rtw89: chan: manage active interfaces

impending MLO support, we need a method to manage relation between active
interfaces and channel contexts. If an interface owns at least one active
link, we call it an active interface. We add a list to manage active ones.

Basically, the list follows the active order except for the below case. To
be compatible with legacy behavior, the first interface that owns the first
channel context will put at the first entry in the list when recalculating.

Besides, MCC can also select and fill roles based on the above active list.

In this case, all four warnings can be easily avoided by splitting the
function into two separate ones, in a way that helps readability as well,
at the expense of a few extra source lines.

63aca17262 wifi: rtw89: add thermal protection
To prevent chip overheating, reduce TX duty as the mechanism of thermal
protection. When temperature is raising over a threshold, send a firmware
command to reduce TX duty. If temperature is still raising, higher level
is adopted to have lower active duration.

The equation and unit of thermal values are different from chip to chip,
so define constant thresholds of thermal value to corresponding absolute
temperature of 110 and 120 degree Celsius.

Latter patch will decide which thermal threshold is adopted, and current
is still not enable thermal protection.

For debugging, add a flag to disable_dm that thermal protection can be
disabled to clarify low throughput in field.

The type of tsf arithmetic is
   u64 += u16 * int;

When (u16 * int) is larger than 0x7FFFFFFF, the value casting to u64 with
sign-extension will become all 1 in upper 32 bits part.

To meet the case, u16 value should be larger than 20491
(0x7FFFFFFF / 104800). Fortunately the meaning of 20491 is delay time of
WoWLAN net detection in unit of second, so 20491 seconds (5.7 hours)
might not a real case we can meet.

d241a139c2 wifi: mwifiex: Fix memcpy() field-spanning write warning in mwifiex_config_scan()
Replace one-element array with a flexible-array member in `struct
mwifiex_ie_types_wildcard_ssid_params` to fix the following warning
on a MT8173 Chromebook (mt8173-elm-hana):

[  356.775250] ------------[ cut here ]------------
[  356.784543] memcpy: detected field-spanning write (size 6) of single field "wildcard_ssid_tlv->ssid" at drivers/net/wireless/marvell/mwifiex/scan.c:904 (size 1)
[  356.813403] WARNING: CPU: 3 PID: 742 at drivers/net/wireless/marvell/mwifiex/scan.c:904 mwifiex_scan_networks+0x4fc/0xf28 [mwifiex]

The "(size 6)" above is exactly the length of the SSID of the network
this device was connected to. The source of the warning looks like:

    ssid_len = user_scan_in->ssid_list[i].ssid_len;
    [...]
    memcpy(wildcard_ssid_tlv->ssid,
           user_scan_in->ssid_list[i].ssid, ssid_len);

There is a #define WILDCARD_SSID_TLV_MAX_SIZE that uses sizeof() on this
struct, but it already didn't account for the size of the one-element
array, so it doesn't need to be changed.
