4c8d5c8d07 wifi: iwlwifi: mvm: tell firmware about per-STA MFP enablement 
Indicate to the firmware for each station whether or not MFP
is used with this station. Note that we indicate MFP for it
before authorized since we don't know yet, and that will make
the firmware not handle should-be-protected management frames
without being able to check them.

fccf5ff14e wifi: iwlwifi: mvm: remove warning for beacon filtering error 
This warning is sometimes happening if we force a FW error
while disconnecting, which is annoying but harmless.

However, it's also pointless to throw a warning here, since
the stack and driver state doesn't really help, so just
remove that so the driver will ignore the error if any.

3b67a20bb0 wifi: iwlwifi: mvm: offload BTM response during D3 
There are mainly two types of BTM (BSS Transition Management)
requests, recommendations and notifications. For the first type,
a response is needed otherwise, most probably the STA will be
disconnected.
Since we don't want to wake up the host on it, set the BTM to reject
offload flag (if the device supports it) and rely on the FW to take
care of it. The FW will reject the BTM request and in case the AP
sends DEAUTH the FW can wake up the host to let it decide on the
next steps.

DRAM buffers that are not defined in the TLVs (or are unused in the

buffers with an invalid (i.e. uninitialized) DRAM path.

1f1784a59c wifi: rtw88: usb: silence log flooding error message 
When receiving more rx packets than the kernel can handle the driver
drops the packets and issues an error message. This is bad for two
reasons. The logs are flooded with myriads of messages, but then time
consumed for printing messages in that critical code path brings down
the device. After some time of excessive rx load the driver responds
with:

rtw_8822cu 1-1:1.2: failed to get tx report from firmware
rtw_8822cu 1-1:1.2: firmware failed to report density after scan
rtw_8822cu 1-1:1.2: firmware failed to report density after scan

The device stops working until being replugged.

Fix this by lowering the priority to debug level and also by
ratelimiting it.

daef020558 wifi: ray_cs: remove one redundant del_timer 
In ray_detach, it and its child function ray_release both call
del_timer(_sync) on the same timer.

Fix this by removing the del_timer_sync in the ray_detach, and revising
the del_timer to del_timer_sync.

different, so add a variable to store the length according to chip and

The register ranges of upcoming chips are different from current, and even
existing chips have different ranges, so support longer length to dump
registers. Then, user space can decide the ranges according to chip.

Since arbitrary length (e.g. 7) would be a little complicated, so simply
make length a multiple of 16. The output looks like
