After sending DPP Auth Response, the Responder might not receive the
Auth Confirm either due to the Initiator not sending it or the reception
of the frame failing for some reason (e.g., Responder having already
left the negotiation channel). If this happens, following initiation
attempts would fail since the consecutive Auth Request would get
discarded since the previous authentication is still in progress.
Terminate DPP authentication on Responder, if no Auth Confirm is
received within one second of successfully sending Auth Response. This
allows the Responder to accept start of a new exchange.

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
replaced in practice and as such, there is no need to try continue that
association any further.

This was added to the protocol design to support cases where the
C-sign-key uses a different group than the netAccessKey. The Enrollee
now indicates its netAccessKey group in Reconfig Announcement and the
Configurator builds it own reconfig Connector using that group instead
of the group used for the C-sign-key.

This fixes an issue where the pending authentication might have held a

from the list.

Do not use a random MAC address for the GAS exchange that is used as
part of the DPP protocol exchange since that would break DPP.
Configurator expects the same MAC address to be used for DPP
Authentication exchange and DPP Configuration exchange (GAS).
Since the DPP Authentication exchange has already used the MAC address
configured on the interface, use of a random address for the GAS
exchange would not provide any additional privacy protection. If a
random MAC address needs to be used for this type of an exchange, that
random address would need to be first configured on the interface before
starting DPP exchange.
This does not change GAS query behavior for any other use case, i.e.,
the gas_rand_mac_addr configuration continues to apply to all the
Interworking/Hotspot 2.0 uses.
