We have new features for both ath11k and ath12k. ath12k is now under
heavy refactoring in preparation for MLO support.

Major changes:

ath12k

* refactoring in preparation for Multi-Link Operation (MLO) support

* 1024 Block Ack window size support

* provide firmware wmi logs via a trace event

ath11k

* 36 bit DMA mask support

* support 6 GHz station power modes: Low Power Indoor (LPI), Standard
  Power) SP and Very Low Power (VLP)

This *mostly* reverts commit 1e1b11b6a111 ("nl80211/cfg80211: Specify
band specific min RSSI thresholds with sched scan").

During the review of a new patch [1] it was observed that the
functionality being modified was not actually being used by any
in-tree driver. Further research determined that the functionality was
originally introduced to support a new Android interface, but that
interface was subsequently abandoned. Since the functionality has
apparently never been used, remove it. However, to mantain the
sanctity of the UABI, keep the nl80211.h assignments, but clearly mark
them as obsolete.

wifi: iwlwifi: add support for a wiphy_work rx handler

The wiphy_work infra ensures that the entire worker will run
with the wiphy mutex. It is useful to have RX handlers
running as a wiphy_work, when we don't want the handler to
run in parallel with mac80211 work (to avoid races).

For example - BT notification can disable eSR starting from the next
patch.
In ieee80211_set_active_links we first check that eSR is
allowed, (drv_can_activate_links) and then activate it.
If the BT notif was received after drv_can_activate_links
(which returned true), and before the activation - eSR will be
activated when it shouldn't.
If BT notif is handled with the wiphy mutex, it can't run in
parallel to ieee80211_set_active_links, which also holds that
mutex.

Add the necessary infrastructure here, for use in the next commit.

wifi: cfg80211: add support for SPP A-MSDUs

Add SPP (signaling and payload protected) AMSDU support.

Since userspace has to build the RSNX element, add an extended
feature flag to indicate that this is supported.

In order to avoid downgrade/mismatch attacks, add a flag to the assoc
command on the station side, so that we can be sure that the value of
the flag comes from the same RSNX element that will be validated by
the supplicant against the 4-way-handshake. If we just pulled the
data out of a beacon/probe response, we could theoretically look an
RSNX element from a different frame, with a different value for this
flag, than the supplicant is using to validate in the
4-way-handshake.

Note that this patch is only geared towards software crypto
implementations or hardware ones that can perfectly implement SPP
A-MSDUs, i.e. are able to switch the AAD construction on the fly for
each TX/RX frame.

For more limited hardware implementations, more capability
advertisement  would be required, e.g. if the hardware has no way
to switch this on the fly but has only a global configuration that
must apply to all stations.

The driver could of course *reject* mismatches, but the supplicant
must know so it can do things like not negotiating SPP A-MSDUs on
a T-DLS link when connected to an AP that doesn't support it, or
similar.

wifi: mac80211: process and save negotiated TID to Link mapping request

An MLD may send TID-to-Link mapping request frame to negotiate
TID to link mapping with a peer MLD.
Support handling negotiated TID-to-Link mapping request frame
by parsing the frame, asking the driver whether it supports the
received mapping or not, and sending a TID-to-Link mapping response
to the AP MLD.
Theoretically, links that became inactive due to the received TID-to-Link
mapping request, can be selected to be activated but this would require
tearing down the negotiated TID-to-Link mapping, which is still not
supported.

selftests: Updates to fcnal-test for autoamted environment

The first patch updates the PATH for fcnal-test.sh to find the nettest
binary when invoked at the top-level directory via
   make -C tools/testing/selftests TARGETS=net run_tests

Second patch fixes a bug setting the ping_group; it has a compound value
and that value is not traversing the various helper functions in tact.
Fix by creating a helper specific to setting it.

Third patch adds more output when a test fails - e.g., to catch a change
in the return code of some test.

With these 3 patches, the entire suite completes successfully when
run on Ubuntu 23.10 with 6.5 kernel - 914 tests pass, 0 fail.

The peer delete logic in ath11k_mac_op_unassign_vif_chanctx() is
introduced by commit b4a0f54156ac ("ath11k: move peer delete after
vdev stop of station for QCA6390 and WCN6855") to fix firmware
crash issue caused by unexpected vdev stop/peer delete sequence.

Actually for a STA interface peer should be deleted in
ath11k_mac_op_sta_state() when STA's state changes from
IEEE80211_STA_NONE to IEEE80211_STA_NOTEXIST, which also coincides
with current peer creation design that peer is created during
IEEE80211_STA_NOTEXIST -> IEEE80211_STA_NONE transition. So move
peer delete back to ath11k_mac_op_sta_state(), also stop vdev before
deleting peer to fix the firmware crash issue mentioned there. In
this way the connection failure mentioned here is also fixed.

In ath11k_mac_op_assign_vif_chanctx(), there is a logic to
create peer using ar->mac_addr for a STA vdev. This is invalid
because a STA vdev should have a peer created using AP's
MAC address. Besides, if we run into that logic, it means a peer
has already been created earlier, we should not create it again.
So remove it.

This is found during code review.

wifi: ath11k: enable 36 bit mask for stream DMA

Currently 32 bit DMA mask is used, telling kernel to get us an DMA
address under 4GB when mapping a buffer. This results in a very high
CPU overhead in the case where IOMMU is disabled and more than 4GB
system memory is installed. The reason is, with more than 4GB memory
installed, kernel is likely to allocate a buffer whose physical
address is above 4GB. While with IOMMU disabled, kernel has to involve
SWIOTLB to map/unmap that buffer, which consumes lots of CPU cycles.

We did hit an issue caused by the reason mentioned above: in a system
that disables IOMMU and gets 8GB memory installed, a total of 40.5%
CPU usage is observed in throughput test. CPU profiling shows nearly
60% of CPU cycles are consumed by SWIOTLB.

By enabling 36 bit DMA mask, we can bypass SWIOTLB for any buffer
whose physical address is below 64GB. There are two types of DMA mask
within struct device, named dma_mask and coherent_dma_mask. Here we
only enable 36 bit for dma_mask, because firmware crashes if
coherent_dma_mask is also enabled, due to some unknown hardware
limitations. This is acceptable because coherent_dma_mask is used for
mapping a consistent DMA buffer, which generally does not happen in
a hot path.

With this change, the total CPU usage mentioned in above issue drops
to 18.9%.

net: dsa: mt7530: support OF-based registration of switch MDIO bus

Currently the MDIO bus of the switches the MT7530 DSA subdriver controls
can only be registered as non-OF-based. Bring support for registering the
bus OF-based.

The subdrivers that control switches [with MDIO bus] probed on OF must
follow this logic to support all cases properly:

No switch MDIO bus defined: Populate ds->user_mii_bus, register the MDIO
bus, set the interrupts for PHYs if "interrupt-controller" is defined at
the switch node. This case should only be covered for the switches which
their dt-bindings documentation didn't document the MDIO bus from the
start. This is to keep supporting the device trees that do not describe the
MDIO bus on the device tree but the MDIO bus is being used nonetheless.

Switch MDIO bus defined: Don't populate ds->user_mii_bus, register the MDIO
bus, set the interrupts for PHYs if ["interrupt-controller" is defined at
the switch node and "interrupts" is defined at the PHY nodes under the
switch MDIO bus node].

Switch MDIO bus defined but explicitly disabled: If the device tree says
status = "disabled" for the MDIO bus, we shouldn't need an MDIO bus at all.
Instead, just exit as early as possible and do not call any MDIO API.

The use of ds->user_mii_bus is inappropriate when the MDIO bus of the
switch is described on the device tree [1], which is why we don't populate
ds->user_mii_bus in that case.
