-Subject: [PATCH 3/8] Extend protection of GTK/IGTK reinstallation of WNM-Sleep
- Mode cases
-
-This extends the protection to track last configured GTK/IGTK value
-separately from EAPOL-Key frames and WNM-Sleep Mode frames to cover a
-corner case where these two different mechanisms may get used when the
-GTK/IGTK has changed and tracking a single value is not sufficient to
-detect a possible key reconfiguration.
