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! regards Mårten Wikström -----Original Message----- From: vishwanath pargaonkar To: freebsd-net@FreeBSD.ORG Cc: freebsd-hackers@FreeBSD.ORG Sent: 5/22/01 8:52 AM Subject: interface flags Hi, i have freebsd 4.2 stable. what is difference between interface flags IFF_UP and IFF_RUNNING?
