[PATCH net-next 4/5] net: bridge: ensure FDB offloaded flag is handled as needed

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Since user added entries in the bridge FDB will get the BR_FDB_OFFLOADED
flag set, we do not want the bridge to age those entries and we want the
entries to be deleted in the bridge upon an SWITCHDEV_FDB_DEL_TO_BRIDGE
event.
