+Subject: [PATCH 5.3] rt2x00: clear IV's on start to fix AP mode regression
+Date: Mon, 19 Aug 2019 13:20:07 +0200
+Message-Id: <1566213607-6723-1-git-send-email-sgruszka@redhat.com>
+Sender: linux-wireless-owner@vger.kernel.org
+List-ID: <linux-wireless.vger.kernel.org>
+X-Mailing-List: linux-wireless@vger.kernel.org
+
+To do not brake HW restart we should keep initialization vectors data.
+I assumed that on start the data is already initialized to zeros, but
+that not true on some scenarios and we should clear it. So add
+additional flag to check if we are under HW restart and clear IV's
+data if we are not.
+
+Patch fixes AP mode regression.
+
+Reported-and-tested-by: Emil Karlson <jekarl@iki.fi>
+Fixes: 710e6cc1595e ("rt2800: do not nullify initialization vector data")
