+Subject: batman-adv: Fix duplicated OGMs on NETDEV_UP
+
+The state of slave interfaces are handled differently depending on whether
+the interface is up or not. All active interfaces (IFF_UP) will transmit
+OGMs. But for B.A.T.M.A.N. IV, also non-active interfaces are scheduling
+(low TTL) OGMs on active interfaces. The code which setups and schedules
+the OGMs must therefore already be called when the interfaces gets added as
+slave interface and the transmit function must then check whether it has to
+send out the OGM or not on the specific slave interface.
+
+But the commit 0d8468553c3c ("batman-adv: remove ogm_emit and ogm_schedule
+API calls") moved the setup code from the enable function to the activate
+function. The latter is called either when the added slave was already up
+when batadv_hardif_enable_interface processed the new interface or when a
+NETDEV_UP event was received for this slave interfac. As result, each
+NETDEV_UP would schedule a new OGM worker for the interface and thus OGMs
+would be send a lot more than expected.
+
+Fixes: 0d8468553c3c ("batman-adv: remove ogm_emit and ogm_schedule API calls")
