Hello!

Thanks for the information regarding userland/kernelspace - I think I understood ...

The reason of my question were problems using the tun/tap interface - I've got an application (namely l2tpns) demanding the ifreq-structure being copied back to userspace - which AFAIK doesn't happen in case of the TUNSETIFF-ioctl. Is this a bug or are there any reasons why this shouldn't happen in dev_ifsioc ?

Thanks,
Michael
