    Description:
    
       This update for hostapd fixes the following issues:
    
       hostapd was updated to version 2.9:
    
       * SAE changes
         - disable use of groups using Brainpool curves
         - improved protection against side channel attacks

       * fixed FT and SA Query Action frame with AP-MLME-in-driver cases
       * OWE: allow Diffie-Hellman Parameter element to be included with DPP in

           SAE; note: this is not backwards compatible, i.e., both the AP and
           station side implementations will need to be update at the same time
           to maintain interoperability
         - added support for Password Identifier
       * hostapd_cli: added support for command history and completion
       * added support for requesting beacon report
