HW that has bridge capabilities are not required to set their ports in promisc mode when they are added to the bridge. But it is required to enable promisc mode if a user space application requires it. Therefore if the driver listens for events SWITCHDEV_ATTR_ID_PORT_PROMISCUITY and NETDEV_CHANGEUPPER it is possible to deduce when to add/remove ports in promisc mode. v2->v3: - stop using feature NETIF_F_HW_BR_CAP - renmae subject from 'Add NETIF_F_BW_BR_CAP feature' because this feature is not used anymore. v1->v2: - rename feature to NETIF_F_HW_BR_CAP - add better description in the commit message and in the code - remove the check that all network drivers have same netdev_ops and just check for the feature NETIF_F_HW_BR_CAP when setting the network port in promisc mode.
