    mac80211: allow transmitting deauth with tainted key · e54faf29
    Johannes Berg authored
    When we had a connection for WoWLAN and after resume it
    needed to be disconnected, the previous commit enabled
    sending a deauth frame to the AP. This frame would not
    go through on MFP-enabled networks as the key for it is
    marked tainted before the frame is transmitted.
    
    Allow a tainted key to be used for deauth frames. Worst
    case, we'll use a wrong key because the PTK was rekeyed
    while suspended, but more likely the PTK is still fine
    and the taint flag really only applies to the GTK(s).
