Before when a port was added to a bridge then the port was added in promisc mode. But because of the patches: commit e6300374f3be6 ("net: Add NETIF_HW_BR_CAP feature") commit 764866d46cc81 ("net: mscc: Use NETIF_F_HW_BR_CAP")' The port is not needed to be in promisc mode to be part of the bridge. So it is possible to togle the promisc mode of the port even if it is or not part of the bridge.
