IFF_UP indicates that the interface is administratively configured up. IFF_RUNNING indicates that the hardware has been set to an operational state. For Ethernet-like interfaces, which often do not provide a direct link-ready indication to software, IFF_RUNNING is usually not meaningful. (In true historic Ethernets, there was no way for even the hardware to know whether its transceiver was connected to a network or not.) -GAWollman To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
