12c8eacf73 DPP: Allow version number to be overridden for testing purposes
"SET dpp_version_override <ver>" can now be used to request
wpa_supplicant and hostapd to support a subset of DPP versions. In
practice, the only valid case for now is to fall back from DPP version 2
support to version 1 in builds that include CONFIG_DPP2=y.

Discard the FT Reassociation Request frame instead of rejecting it
(i.e., do not send Reassociation Response frame) if RSNXE Used is

While there is not really much of a difference between discarding and
rejecting the frame, this discarding behavior is what the standard says
for this type of an error case.

b7275a8142 Update STA flags to the driver immediately on disconnection

flags on disconnection cases to remove authorization and association.
However, some cases did not result in immediate update of the driver STA

well to reduce risk of race conditions where new frames might be
accepted for TX or RX after the port authorization or association has
been lost and configured keys are removed.
