Activated, to me, sounds like that it has happened as a consequence of
something, and primarily not as a result of a user request.

This flag is also set using MEDIA_IOC_SETUP_LINK ioctl and setting the
flags field would be something like this:

media_link_desc.flags |= MEDIA_LINK_ACTIVATED;

I'd prefer ACTIVE over ACTIVATED, since this may also be set (and is
mostly set) by the user.

But reading this discussion, ACTIVE has not received unanimous approval
either... :\

What would you think about "ENABLED"? It's simple, quite generic and
thus doesn't explicitly suggest what is the exact effect it has on the
level of the underlying device.

I don't completely like it myself since it would be best to have an
adjective (like "active") but there's none for the word enable, so it
bears the same issues than "activated".

Cheers,
