>Description:

The list_net_interfaces() function of /etc/network.subr uses the following code to build list of interfaces when network_interfaces is NOT set to "auto":

                _tmplist="${network_interfaces} ${cloned_interfaces}"

This does not account gif interfaces specified with gif_interfaces option. Of course it is possible to set gif_interfaces equal to cloned_interfaces in the /etc/rc.conf but this will cause "ifconfig gifN create" to be executed twice (second invocation reports error - interface already created)
