As it says in sys/net/if.h, IFF_RUNNING means "resources allocated" and
IFF_UP means "interface is up". As I interpret this, the difference is that
IFF_RUNNING is set when the interface is initialised and indicates that it
is ready to be used. IFF_UP on the other hand is set by the user to indicate
whether this interface is enabled or not. I.e. IFF_RUNNING set by system,
IFF_UP set by user. This however, doesn't seem to be the case in all drivers
though. I would be very pleased if someone could clarify the issue further.
Please correct me if I'm totally wrong!
