bridge: del external_learned fdbs from device on flush or ageout
We need to delete from offload the device externally learnded fdbs when any one of these events happen: 1) Bridge ages out fdb. (When bridge is doing ageing vs. device doing ageing. If device is doing ageing, it would send SWITCHDEV_FDB_DEL directly). 2) STP state change flushes fdbs on port. 3) User uses sysfs interface to flush fdbs from bridge or bridge port: echo 1 >/sys/class/net/BR_DEV/bridge/flush echo 1 >/sys/class/net/BR_PORT/brport/flush 4) Offload driver send event SWITCHDEV_FDB_DEL to delete fdb entry. For rocker, we can now get called to delete fdb entry in wait and nowait contexts, so set NOWAIT flag when deleting fdb entry. Signed-off-by: Scott Feldman <sfeldma@gmail.com> Signed-off-by: David S.
