When everything is done, driver updates internal copy of interface flags sc->if_flags which holds the operational state. So, transmit from Rx path is possible when interface is intended to be administratively down in accordance with ifp->if_flags, but not applied yet and the operational state is up in accordance with sc->if_flags.
