From e4bd44e89dcf37345e4851c5e775cb5abf38ab62 Mon Sep 17 00:00:00 2001 From: Vladimir Oltean Date: Tue, 23 Mar 2021 01:51:52 +0200 Subject: net: ocelot: replay switchdev events when joining bridge The premise of this change is that the switchdev port attributes and objects offloaded by ocelot might have been missed when we are joining an already existing bridge port, such as a bonding interface. The patch pulls these switchdev attributes and objects from the bridge, on behalf of the 'bridge port' net device which might be either the ocelot switch interface, or the bonding upper interface. The ocelot_net.c belongs strictly to the switchdev ocelot driver, while ocelot.c is part of a library shared with the DSA felix driver. The ocelot_port_bridge_leave function (part of the common library) used to call ocelot_port_vlan_filtering(false), something which is not necessary for DSA, since the framework deals with that already there. So we move this function to ocelot_switchdev_unsync, which is specific to the switchdev driver. The code movement described above makes ocelot_port_bridge_leave no longer return an error code, so we change its type from int to void. Signed-off-by: Vladimir Oltean Signed-off-by: David S.
