90e478aa0a DPP2: Use the PFS fallback if multiple key_mgmt values are enabled
Previously this fallback from PFS enabled to disabled (and back to
enabled) was used only if the local network profile used key_mgmt=DPP,
i.e., did not enable another other AKM. That leaves out some valid cases
since the local network profile could actually enable both DPP and SAE.
Extend this check to accept cases DPP AKM is enabled and it was selected
for the connection even if there other enabled AKMs.

93a73ce028 MSCS: Fix issues due to incorrect usage of wpa_hexdump_buf()
Previously wpabuf_head() of the buffer is passed to wpa_hexdump_buf()
instead of the wpabuf struct itself and it was causing wpa_supplicant to
crash. Fix this by using the correct pointer in the debug prints.

1733e356e4 dpp-nfc: Fix handover client wait for receiving handover select
This was supposed to wait for up to 3.0 seconds for the handover select,
but the incorrect loop terminated ended up limiting this to a single
iteration of 0.1 second wait. This was too fast for some cases like the
AP mode operation where it may take significant time to enable the radio
for listening to DPP authentication messages.

Fix the loop to allow that full three second wait for the response to be
used. In addition, report the amount of time it takes to receive the
response.

3adc1c623e DPP2: Disconnect before starting reconfiguration
The offchannel operations (scan, Public Action frame TX/RX) have
significantly more latency when performed while connected, so disconnect
when requested to initiate DPP reconfiguration to avoid this. The old
network profile (i.e., likely the current connection) is going to be

association any further.
