Hi,

I would like to check the interface status (up/down) within linux kernel. Is there any routine (sort of ioctl) to do this. Any code that is already in use in kernel would also be helpful for me. Please let me know.

If you want to check the status of a given "struct net_device *dev", you can do "dev->flags & IFF_UP". No idea how this is supposed to be locked. If you want to be notigied of changes, you can call register_netdevice_notifier(). -Michi -- programing a layer 3+4 network protocol for mesh networks see http://michaelblizek.twilightparadox.com
