    mac80211: allow writing TX PN in debugfs · d0a77c65
    Johannes Berg authored
    For certain tests, for example replay detection, it can be useful
    to be able to influence/set the PN used in outgoing packets. Make
    it possible to change the TX PN in debugfs.
    For now, this doesn't support TKIP since I haven't needed it, but
    there's no reason it couldn't be added if necessary.
    Note that this must be used very carefully: it could, for example,
    be used to make "valid replays" where the PN reuse happens on a
    different TID. This couldn't be done by an attacker since the TID
    is protected as part of the AAD.
