The documentation for it sucks anyway. :) No, it's actually used in a patch I'm about to post: http://johannes.sipsolutions.net/patches/kernel/all/2007-09-28-22%3a38/017-mac80211-key-seq-nl80211.patch Mind you, it could be renamed and described better; it's used for getting the current sequence number of a hardware TKIP implementation. johannes
