This module is similar to SAE in that it communicates over authenticate and associate frames. Creating a new OWE SM requires registering two TX functions that handle sending the data out over CMD_AUTHENTICATE/ASSOCIATE, as well as a complete function. Once ready, calling owe_start will kick off the OWE process, first by sending out an authenticate frame. There is nothing special here, since OWE is done over the associate request/response. After the authenticate response comes in OWE will send out the associate frame which includes the ECDH public key, and then receive the AP's public key via the associate response. From here OWE will use ECDH to compute the shared secret, and the PMK/PMKID. Both are set into the handshake object. Assuming the PMK/PMKID are successfully computed the OWE complete callback will trigger, meaning the 4-way handshake can begin using the PMK/PMKID that were set in the handshake object.
