From 'IEEE Std 802.11-2020 section 11.8.8.4.1':
The mesh channel switch may be triggered by the need to avoid
interference to a detected radar signal, or to reassign mesh STA
channels to ensure the MBSS connectivity.
A 20/40 MHz MBSS may be changed to a 20 MHz MBSS and a 20 MHz
MBSS may be changed to a 20/40 MHz MBSS.
Since the standard allows the change of bandwidth during
the channel switch in mesh, remove the bandwidth check present in
ieee80211_set_csa_beacon.

In ieee80211_tx_dequeue() we currently allow a control port
frame to be transmitted on a non-authorized port only if the
A2 matches the local interface address, but if that's an MLD
and the peer is a legacy peer, we need to allow link address
here. Fix that.

For an AP interface, when userspace specifieds the link ID to
transmit the control port frame on (in particular for the
initial 4-way-HS), due to the logic in ieee80211_build_hdr()
for a frame transmitted from/to an MLD, we currently build a
header with
A1 = DA = MLD address of the peer MLD
A2 = local link address (!)
A3 = SA = local MLD address
This clearly makes no sense, and leads to two problems:
- if the frame were encrypted (not true for the initial
4-way-HS) the AAD would be calculated incorrectly
- if iTXQs are used, the frame is dropped by logic in
ieee80211_tx_dequeue()
Fix the addressing, which fixes the first bullet, and the
second bullet for peer MLDs, I'll fix the second one for
non-MLD peers separately.

in fw/hw, it is necessary to be able to have some information
on the link on which the frame has been received. Extend the

Also make chanes to mac80211 rx APIs to make use of the reported

Since IQK could spend time, we make a cache of IQK result matrix that looks
like iqk_matrix[channel_idx].val[x][y], and we can reload the matrix if we
have made a cache. To determine a cache is made, we check
iqk_matrix[channel_idx].val[0][0].
The initial commit 7274a8c229 ("rtlwifi: rtl8192de: Merge phy routines")
make a mistake that checks incorrect iqk_matrix[channel_idx].val[0] that
is always true, and this mistake is found by commit ee3db469dd

Instead of listing directly properties typical for SPI peripherals,
reference the spi-peripheral-props.yaml schema. This allows using all
properties typical for SPI-connected devices, even these which device
bindings author did not tried yet.
Remove the spi-* properties which now come via spi-peripheral-props.yaml
schema, except for the cases when device schema adds some constraints
like maximum frequency.
While changing additionalProperties->unevaluatedProperties, put it in
typical place, just before example DTS.
