From a31cf1c69e89e0c2d5515b04aca313f1014a714d Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Mon, 20 Apr 2015 18:21:58 +0200 Subject: mac80211: extend get_key() to return PN for all ciphers For ciphers not supported by mac80211, the function currently doesn't return any PN data. Fix this by extending the driver's get_key_seq() a little more to allow moving arbitrary PN data.
