d7febe33f6 MLO: Remove unnecessary debug prints about clearing AP RSNE/RSNXE
There is no help from seeing 32 lines of debug prints about clearing
AP's RSNE/RSNXE information for each potential link when such
information has not been set in the first place. These were printed even
when there is no use of MLO whatsoever, so get rid of the prints for any
case where the value has not yet been set.

16d913bfd8 Define AFC vendor commands and events
Wi-Fi Alliance specification for Automated Frequency Coordination (AFC)
system ensures that the Standard Power Wi-Fi devices can operate in 6
GHz spectrum under favorable conditions, without any interference with
the incumbent devices.

Add support for vendor command/events and corresponding
attributes to define the interface for exchanging AFC requests and
responses between the driver and a userspace application.

46f5cf9280 OpenSSL: Fix additional HPKE corner cases
Commit 820211245b ("OpenSSL: Fix HPKE in some corner cases") increased
the buffer size for EVP_PKEY_derive() by 16 octets, but it turns out
that OpenSSL might need significantly more room in some cases. Replace a
fixed length buffer with dynamic query for the maximum size and
allocated buffer to cover that need.

This showed up using the following test case sequence:

48dd8994ac Fix external passwords with 4-way handshake offloading
Passphrases/PSKs from external password databases were ignored if 4-way
handshake offloading was supported by the driver. Split the PSK loading
functionality into a separate function and calls if to get the PSK for
handshake offloading.

I tested connecting to a WPA2-PSK network with both inline and external
passphrases, using the iwlwifi and brcmfmac drivers.

c6f8af507e Add option to disable SAE key_mgmt without PMF
Add the `sae_check_mfp` global option to limit SAE when PMF will
not be selected for the connection.
With this option SAE is avoided when the hardware is not capable
of PMF due to missing ciphers.
With this option SAE is avoided on capable hardware when the AP
does not enable PMF.

Allows falling back to PSK on drivers with the
WPA_DRIVER_FLAGS_SAE capability but do not support the BIP cipher
necessary for PMF. This enables configurations that can fall back
to WPA-PSK and avoid problems associating with APs configured
with `sae_require_mfp=1`.

Useful when `pmf=1` and `sae_check_mfp=1` are enabled and networks
are configured with ieee80211w=3 (default) and key_mgmt="WPA-PSK SAE".
In this configuration if the device is unable to use PMF due to
lacking BIP group ciphers it will avoid SAE and fallback to
WPA-PSK for that connection.

2e73394426 P2P: Discount current operating frequency when scanning new connection
When scanning for a new connection, we currently optimize by scanning
all frequencies only when our MCC capabilities will allow an additional
operating frequency, and scan only the existing operating frequencies
otherwise. This is problematic when there the current operating
frequency singularly accounts for one of the shared radio frequencies

to the channel count. Fix this.
