>   network.subr:	improve configuration of cloned gif(4) interfaces
>   
>   ifconfig(8) syntax allows to specify only single address_family,
>   so we need additional invocation of ifconfig to support configuration
>   of cloned gif interface that may use different address families
>   for its internal and external addresses.
>   
>   Also, ifconfig(8) does not allow to omit "inet6" keyword for address family
>   specifying IPv6 addresses as outer addresses of the interface.
>   
>   Also, address_family is not "parameter" and it has to go before parameters
>   including "tunnel" keyword, so "ifconfig gif0 tunnel inet6 $oip1 $oip2" would be
>   wrong syntax and only "ifconfig gif0 inet6 tunnel $oip1 $oip2" is right.
>   
>   With this change, the following works:
>   
>   gifconfig_gif0="inet6 2a00::1 2a01::1"
>   ifconfig_gif0="inet 10.0.0.1 10.0.0.2 netmask 255.255.255.252"

If you want another fun one to wrestle with see if you can
make this work:

cloned_interfaces="vlan32"
ifconfig_em0="up"
ifconfig_vlan32="vlan 32 vlandev em0 SYNCDHCP"

I have worked around it, but it would be nice if this "just worked".
