Hello,

Has anyone had time to look at this issue? I could try to come up with a =
fix myself but I=92d first like to know what is the proper way configure =
gif(4) interfaces with FreeBSD 10. If gif_interfaces is deprecated then =
is gifconfig_gifX also deprecated? If gifconfig_gifX is also deprecated =
then this is a documentation issue and also the rc(8) scripts should =
warn about using it like they do now warn about gif_interfaces. If =
gifconfig_gifX is still valid then something must be done about the =
handling of cloned_interfaces in rc.conf.
