network interfaces and IFF_XX flags

Question

I would like to understand if there are any conventions set up in kernel programming when creating network interfaces in the kernel and initializing interface flags, such as IFF_UP, or IFF_MULTICAST etc. What flags must be configured at minimum -- is there any requirement for this?

Thanks.

Take a look at http://man7.org/linux/man-pages/man7/netdevice.7.html, which is the man page for NETDEVICE(7). In there, you will see a list of flags under SIOCSIFFLAGS and SIOCCIFFLAGS.

Standard interface flags are described at include/linux/if.h.

See comments for details.
