And that's true: we have run out of IFF flags in tun.
So let's not try to add more: add simple GET/SET ioctls
instead. Easy to test, leads to clear semantics.
Alternatively we'll have to revert the whole thing for 3.19,
but that seems more work as this has dependencies
in other places.
While here, I noticed that macvtap was actually reading
ifreq flags as a 32 bit field.
Fix that up as well.
Looks good, series applied, thanks.
