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.)
