As far as the related CVE-2017-13084 (reinstallation of the STK key in
the PeerKey handshake) is concerned, it should be noted that PeerKey
implementation in wpa_supplicant is not fully functional and the actual
installation of the key into the driver does not work. As such, this
item is not applicable in practice. Furthermore, the PeerKey handshake
for IEEE 802.11e DLS is obsolete and not known to have been deployed.
