e7aeb6d8ac SAE-PK: STA functionality
This adds STA side functionality for SAE-PK. This version enables SAE-PK
automatically based on the configured SAE password value if the selected
AP advertises support for SAE-PK.

Convert the previously used text log entries to use the more formal

Make reporting of OCV validation failure reasons more flexible by
removing the fixed prefix from ocv_verify_tx_params() output in
ocv_errorstr so that the caller can use whatever prefix or encapsulation
that is most appropriate for each case.

2d118f557a OCV: Add support to override channel info OCI element (STA)
To support the STA testbed role, the STA has to use specified channel
information in OCI element sent to the AP in EAPOL-Key msg 2/4, SA Query
Request, and SA Query Response frames. Add override parameters to use
the specified channel while populating OCI element in all these frames.

c2080e8657 Clear current PMKSA cache selection on association/roam
It was possible for the RSN state machine to maintain old PMKSA cache
selection (sm->cur_pmksa) when roaming to another BSS based on
driver-based roaming indication. This could result in mismatching state
and unexpected behavior, e.g., with not generating a Suite B PMKSA cache
entry.
