==================
rtw-next patches for -next
Improve MLO and some random fixes. Notable changes are:
* drop usb device reference across drivers
rtw89:
* add RTL8922DE but not enabled yet, because BT coexistence is still
cooking.
* add USB RX aggregation to improve performance.
* add USB TX flow control by tracking in-flight URBs.

rtw89_usb_ops_check_and_reclaim_tx_resource() returns a hardcoded
placeholder value (42) instead of actual TX resource availability.
This violates mac80211's flow control contract, preventing backpressure
and causing uncontrolled URB accumulation under sustained TX load.
Fix by adding per-channel atomic counters (tx_inflight[]) that track
in-flight URBs. Increment before usb_submit_urb() with rollback on
failure, decrement in the completion callback, and return the
remaining capacity to mac80211. The firmware command channel (CH12)
always returns 1 since it has its own flow control.
The pre-increment pattern prevents a race where USB core completes the
URB on another CPU before the submitting code increments the counter.
128 URBs per channel provides headroom for RTL8832CU at 160 MHz
bandwidth. Tested on RTL8852AU (USB3 80 MHz) where 64 and 128 showed
equivalent throughput, and on RTL8832AU where 128 sustained full
throughput under 8-stream parallel load.
Tested on D-Link DWA-X1850 (RTL8832AU), kernel 6.19.8, Fedora 43:
Unpatched -> Patched (128 URBs)
USB3 5GHz UL: 844 -> 837 Mbps (no regression)
USB3 5GHz retx: 3 -> 0
USB3 2.4GHz UL: 162 -> 164 Mbps (no regression)
4-stream UL: 858 -> 826 Mbps (within variance)
8-stream UL: 872 -> 826 Mbps (within variance)
UDP flood: 0% loss (690K datagrams)
60-second soak: 855 Mbps, 0 retransmits

The chips ops related to RF calibration include init, init_late, channel,
band_change, scan, and track. The init_late is similar to init, but HCI
is ready, so receiving C2H event is possible. The ops channel is the main
function that do all RF calibration on operating channel.
The ops band_change and scan are to reset RF calibration because channel is
switching at these moment, we need to reset RF state. The ops track is to
monitor temperature to check if re-calibrate RF again.

Sometimes while watching a Youtube video with Bluetooth headphones the
audio has a lot of interruptions, because the 5th byte of the BT info
sent by RTL8821AU has strange values, which result in
coex_stat->bt_hid_pair_num being 2 or 3. When this happens
rtw_coex_freerun_check() returns true, which causes
rtw_coex_action_wl_connected() to call rtw_coex_action_freerun() instead
of rtw_coex_action_bt_a2dp().
The RTL8821AU vendor driver doesn't do anything with the 5th byte of the
BT info, so ignore it here as well.

rtw89_phy_cfo_set_crystal_cap()
In the rtw89_phy_cfo_set_crystal_cap() function, for chips other than
RTL8852A/RTL8851B, the values read by rtw89_mac_read_xtal_si() are
stored into the local variables sc_xi_val and sc_xo_val. If either
read fails, these variables remain uninitialized, they are later
used to update cfo->crystal_cap and in debug print statements. This
can lead to undefined behavior.
Fix the issue by initializing sc_xi_val and sc_xo_val to zero,
like is implemented in vendor driver.

On Radxa Rock 5B with a RTL8852BE combo WiFi/BT card, the efuse
physical map dump intermittently fails with -EBUSY during probe.
The failure occurs in rtw89_dump_physical_efuse_map_ddv() where
read_poll_timeout_atomic() times out waiting for the B_AX_EF_RDY
bit after 1 second.
The root cause is a timing race during boot: the WiFi driver's
chip initialization (firmware download via PCIe) overlaps with
Bluetooth firmware download to the same combo chip via USB. This
can leave the efuse controller temporarily unavailable when the
WiFi driver attempts to read the efuse map.
The firmware download path retries up to 5 times, but the efuse
read that follows has no similar logic. Address this by adding
retry loop logic (also up to 5 attempts) around physical efuse
map dump.

When filling out the TX descriptor, Null data frames are treated like
management frames, but QOS Null data frames are treated like normal
data frames. Somehow this causes a problem for the firmware.
When connected to a network in the 2.4 GHz band, wpa_supplicant (or
NetworkManager?) triggers a scan every five minutes. During these scans
mac80211 transmits many QOS Null frames in quick succession. Because
these frames are marked with IEEE80211_TX_CTL_REQ_TX_STATUS, rtw88
asks the firmware to report the TX ACK status for each of these frames.
Sometimes the firmware can't process the TX status requests quickly
enough, they add up, it only processes some of them, and then marks
every subsequent TX status report with the wrong number.
The symptom is that after a while the warning "failed to get tx report
from firmware" appears every five minutes.
This problem apparently happens only with the older RTL8723D, RTL8821A,
RTL8812A, and probably RTL8703B chips.
Treat QOS Null data frames the same way as Null data frames. This seems
to avoid the problem.
Tested with RTL8821AU, RTL8723DU, RTL8811CU, and RTL8812BU.

Fix connection issue caused by AMPDU frames with abnormal PN patterns
(out-of-order packets with correct MPDU sequence numbers but paired
with abnormal PN values, which is next PN of previous in-order packet).
This is causing packet drops, low throughput and disconnections. It is
observed in fields with some specific AP firmwares. Do this workaround for
better interoperability since some APs could never receive a proper FW
update.

Now, stack has introduced wiphy lock. And, the normal paths calling
RF read/write should be under wiphy lock. So, replace RF mutex with
wiphy lock assertion. Besides, in dbgfs paths, add the corresponding
lock option.

Before entering WoWLAN mode, the driver must ensure that
all received packets have been processed to prevent packet
loss. Consequently, a retry mechanism has been implemented
to guarantee completion.

Since MLD vif can do MLSR switch, it may not always run on HW band 0.
But when preparing MCC for MLD + P2P, P2P vif needs to use HW band 0
to handle connection, i.e. uses of HW bands may be different by vif.
The current major role/vif can be indicated through entity mode. So,
based on it, recalculate MLO DBCC mode to change use of HW band.

The original channel is swapped out for the target channel during ROC.
And, all vifs/links accessing the original channel will be marked with
off-channel. So, it doesn't seem necessary for chan.c to determine which
link instance it is.

The support_mlo flag depends on FW features, so it's determined at runtime.
Since Wi-Fi 7 chip now needs to initialize second HW band, if support_mlo
is not allowed, second HW band might act without settings of TX power and
channel. So, set that for Wi-Fi 7 chip.

Some dynamic mechanism (DM) may need to be disabled during some normal
processes rather than debugging. For example, should not do MLSR switch
during SCAN/ROC or even MCC. So, move the disabling DM functions to core
for impending uses.
No logic changes.

When RA (Rate Adaptive) does try higher rate, a TRY bit is flagged, and
hardware will reference registers configured by this patch as maximum
number of AMPDU. To prevent aggregate too many MPDU over peer's capability
causing loss in peer side, set the minimum values across all stations and
TID since there is single one register per hardware band. Consider MLD
case, a BA session can run across two hardware bands, so set the same
value as well.
