-Subject: batman-adv: Don't schedule OGM for disabled interface
-
-From: Sven Eckelmann <sven@narfation.org>
-
-commit 8e8ce08198de193e3d21d42e96945216e3d9ac7f upstream.
-
-A transmission scheduling for an interface which is currently dropped by
-batadv_iv_ogm_iface_disable could still be in progress. The B.A.T.M.A.N. V
-is simply cancelling the workqueue item in an synchronous way but this is
-not possible with B.A.T.M.A.N. IV because the OGM submissions are
-intertwined.
-
-Instead it has to stop submitting the OGM when it detect that the buffer
-pointer is set to NULL.
