driver during Reassociation Response frame +processing if the first attempt of setting the TK succeeded. This avoids +issues related to clearing the TX/RX PN that could result in reusing +same PN values for transmitted frames (e.g., due to CCM nonce reuse and +also hitting replay protection on the receiver) and accepting replayed +frames on RX side. + +This issue was introduced by the commit +0e84c25434e6a1f283c7b4e62e483729085b78d2 ('FT: Fix PTK configuration in +authenticator') which allowed wpa_ft_install_ptk() to be called multiple +times with the same PTK.
