[ Upstream commit de8dd096949820ce5656d41ce409a67603e79327 ]
Both usb_kill_urb() and usb_free_urb() do the NULL check itself, so there
is no need to duplicate it prior to calling.

[ Upstream commit 3391ee7f9ea508c375d443cd712c2e699be235b4 ]
In 'rtl92c_dm_check_edca_turbo()', 'rtl88e_dm_check_edca_turbo()',
and 'rtl8723e_dm_check_edca_turbo()', the DL limit should be set
from the corresponding field of 'rtlpriv->btcoexist' rather than
UL. Compile tested only.

commit 2e1b3ae3e1f2cf5a3c9c05d5f961d7d4257b489f upstream.
The MAC address is stored at offset 0x107 in the EEPROM, like correctly
stated in the comment. Add a two bytes reserved field right before the
MAC address to shift it from offset 0x105 to 0x107.
With this the MAC address returned from my RTL8723du wifi stick can be
correctly decoded as "Shenzhen Four Seas Global Link Network Technology
Co., Ltd."

[ Upstream commit 5d7cf67f72ae34d38e090bdfa673da4aefe4048e ]
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.
Rephrase the text in the kernel source where the word ordering is
wrong.

[ Upstream commit 942999c48cb382feb53c6da7679a994c97963836 ]
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:

[ Upstream commit 59b4cc439f184c5eaa34161ec67af1e16ffabed4 ]
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.

commit 290564367ab7fa7e2048bdc00d9c0ad016b41eea upstream.
After rtw_usb_alloc_rx_bufs() has been called rx urbs have been
allocated and must be freed in the error path. After rtw_usb_init_rx()
has been called they are submitted, so they also must be killed.
Add these forgotten steps to the probe error path.
Besides the lost memory this also fixes a problem when the driver
fails to download the firmware in rtw_chip_info_setup(). In this
case it can happen that the completion of the rx urbs handler runs
at a time when we already freed our data structures resulting in
a kernel crash.

RX full flags are raised if certain types of RX FIFO are full, and then
drop all following MPDU of AMPDU. In order to resume to receive MPDU
when RX FIFO becomes available, we clear the register bits by the
commit a0d99ebb3ecd ("wifi: rtw89: initialize DMA of CMAC"). But, 8852AE
needs more settings to support this. To quickly fix disconnection problem,
revert the behavior as before.

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

Without this patch, firmware only track beacons for port 0 and since
we will always start AP on port 0, this results in misbehavior of
power saving mode on other ports after AP stops.
The "default port" H2C command is used to notify which port should
firmware track. Update the correct settings to firmware so power
saving mode can work properly.

Broadcast and multicast packets in high queue should be transmitted
all at once during DTIM. But without proper settings, hardware fails
to recognize that there are multiple packets and fetches only one.
Fix this by signaling hardware with more data bit set when there are
packets in the high queue.

In the wpa_supplicant rekey flow, it sends an EAPOL packet 4/4 through
nl80211_tx_control_port() and triggers wake_tx_queue() in the driver.
Then, it sends nl80211_new_key() to configure a new key in mac80211.
However, in wake_tx_queue(), a workqueue is used to process the tx packet,
which might cause the driver to process the EAPOL packet later than
nl80211_new_key(). As a result, the EAPOL 4/4 packet is dropped by mac80211
due to the rekey configuration being finished. The EAPOL packets belongs to
VO packets that need high priority. Therefore, we process VO packets
directly without workqueue to ensure that packets can process immediately.
VO is normally used by voice application that is low traffic load and low
latency, that doesn't affect user experience.
We test iperf with VO packets(iperf3 -P4 -u -b 10000M -S 0xdf)

For combo chips, antennas were controlled by bluetooth only during
power on. If WiFi wish to do transmission, notification to the coexistence
module are required. Previously we only do this before authentication.
To allow transmission before auth, such as management TX, now we start
the initiation of coexistence earlier so antennas are shared between
WiFi and bluetooth after set_channel(), and frames could then be sent.

The key condition to check in wrapper of setting TX power is whether entity
is active or not. Before entity is active, we restrict TX power from being
set by outside callers, e.g. SAR/regulatory.
We mark entity as inactive when powering off MAC. Then, we will mark it as
active when we initialize HW channel stuffs after MAC power on. Although we
can get an active entity after leaving idle phase, TX power doesn't be set
well for default channel until stack set target channel for connection. It
causes that RF things cannot use better TX power during this interval.
Below are some cases which may encounter this or a similar situation.
* hw scan process before connection
As described above.
* right after restart hardware process (SER L2)
HW stuffs of target channel is initialized after mac80211 restart
hardware, but we unexpectedly need to wait one more command to set
channel again or to set TX power.
To fix it and improve RF behavior in that interval, during setting channel,
we don't need to check entity state before setting TX power, which actually
is used to restrict outside callers. It means we call chip ops directly to
replace the wrapper call. Then, TX power can be initialized as long as we
initialize/setup HW stuffs on one channel.
Besides, all chips should configure ops of setting TX power, so we remove
trivial check on pointer.
