int sae_process_commit(struct sae_data *sae);
SAE: Add support for Anti-Clogging mechanism hostapd can now be configured to use anti-clogging mechanism based on the new sae_anti_clogging_threshold parameter (which is dot11RSNASAEAntiCloggingThreshold in the standard). The token is generated using a temporary key and the peer station's MAC address. wpa_supplicant will re-try SAE authentication with the token included if commit message is rejected with a token request.
