248264c622 DPP: Stop Authentication Request attempts if no response after ACK
If unicast Authentication Request frame is used and the peer ACKs such a
frame, but does not reply within the two second limit, there is no need
to continue trying to retransmit the request frames since the peer was
found, but not responsive.

00d2d13db2 DPP: Retry PKEX Exchange Request frame up to five times
Retransmit the PKEX Exchange Request frame if no response from a peer is
received. This makes the exchange more robust since this frame is sent
to a broadcast address and has no link layer retries.

indicate a specific behavior. This is only available in
CONFIG_TESTING_OPTIONS=y builds.

This commit include cases for an extra attribute being added after the
Wrapped Data attribute and Initiator/Responder capabilities having an
unexpected zero capability.

1 = report received configuration to an external program and generate
    a network profile internally, but do not automatically connect
