Different interfaces have its own link-related power save mechanism.
Such as PCI can enter L1 state based on the traffic on the link, and
sometimes driver needs to enable/disable it to avoid some issues, like
throughput degrade when PCI trying to enter L1 state even if driver is
having heavy traffic.
For now, rtw88 only supports PCIE chips, and they just need to disable
ASPM L1 when driver is not in power save mode, such as IPS and LPS.

By Realtek's design, there are two HW modules associated for CLKREQ,
one is responsible to follow the PCIE host settings, and another
is to actually working on it. But the module that is actually working
on it is default disabled, and driver should enable that module if
host and device have successfully sync'ed with each other.
The module is default disabled because sometimes the host does not
support it, and if there is any incorrect settings (ex. CLKREQ# is
not Bi-Direction), device can be lost and disconnected to the host.
So driver should first check after host and device are sync'ed, and
the host does support the function and set it in configuration
space, then driver can turn on the HW module to working on it.

It is because 8192cu doesn't implement usb_cmd_send_packet(), and this
patch just frees the skb within the function to resolve memleak problem
by now. Since 8192cu doesn't turn on fwctrl_lps that needs to download
command packet for firmware via the function, applying this patch doesn't
affect driver behavior.

The LPS threshold was set to 2, means driver will leave LPS
mode if there is more than 2 frames TX/RX for every 2 seconds.
This makes driver enter/leave LPS frequently even if we just
"ping -i1" to the others.
Apparently we do not want to leave LPS mode if there is only
some background traffics or web surfing. By experiment, set
this to 50 is a more reasonable value to lower the over all
power consumption.

Also rearrange the if..else statements because DESC_RATEMCS0 is

This commit adds several Tx/Rx physical information to phy_info
debugfs for 8822B/8822C. By this debugfs, we can know physical
information, such as Tx/Rx rate, RSSI, EVM,SNR, etc. The
information is gotten from the packets of Tx/Rx path. It has
no impact for the performance of 8822B/8822C.
In the fields, we may meet different kinds of problems, but
we may have no professional instrument to check them. At
this moment, this debugfs is a good tool, and it may provide

Enable MU-MIMO transmit beamformee support for chipset 8822b and 8822c.
If the driver is in station mode and associated with an AP, and the
capabilities of both meet the requirement of beamforming, driver will
run as a beamformee and the corresponding chip settings will be set.
In addition, module parameter support_bf is added to enable or disable
beamforming. Sometimes driver will need to disable for inter-operate
issues, and it would be easier for driver to debug.

The temperature of the chip can affect the output power
of the RF components. Hence driver requires to compensate
the power by adjusting the power index recorded in the
power swing table.
And if the difference of current thermal value to the
default thermal value exceeds a threshold, the RF IQK
should be triggered to re-calibrate the characteristics
of the RF components, to keep the output IQ vectors of
the RF components orthogonal enough.

In commit 8020919a9b99 ("mac80211: Properly handle SKB with radiotap
only"), buffers whose length is too short cause a WARN_ON(1) to be
executed. This change exposed a fault in rtlwifi drivers, which is fixed
by regarding packets with skb->len <= FCS_LEN as though they are in error
and dropping them. The test is now annotated as likely.

Nicolas Waisman noticed that even though noa_len is checked for
a compatible length it's still possible to overrun the buffers
of p2pinfo since there's no check on the upper bound of noa_num.
Bound noa_num against P2P_MAX_NOA_NUM.

The RTL8723BU has problems connecting to AP after each warm reboot.
Sometimes it returns no scan result, and in most cases, it fails
the authentication for unknown reason. However, it works totally
fine after cold reboot.
Compare the value of register SYS_CR and SYS_CLK_MAC_CLK_ENABLE
for cold reboot and warm reboot, the registers imply that the MAC
is already powered and thus some procedures are skipped during
driver initialization. Double checked the vendor driver, it reads
the SYS_CR and SYS_CLK_MAC_CLK_ENABLE also but doesn't skip any
during initialization based on them. This commit only tells the
RTL8723BU to do full initialization without checking MAC status.

The use of u8 and __le16 in this struct assumes that it's going to be
packed to byte alignment. C doesn't guarantee that, so we should mark
this __packed.

With shallow buffer size, certain BT devices have active
A2DP flow control to fill buffer frequently. If the slot
is not at BT side, data can't be sent successfully to BT
devices, and will cause audio glitch.
To resolve this issue, this commit splits TUs into 4-slots
instead of 2-slot for all of the A2DP related coexistence
strategies. That makes BT have higher opportunity to fill
the A2DP buffer in time, and the audio quality could be
more stable and smooth.
