I believe that most of gifconfig was rolled into ifconfig. You can
use 'ifconfig gif0 create' to dynamically create gif devices. You
create tunnels using the 'tunnel' option to ifconfig:

    tunnel src_addr dest_addr
            (IP tunnel devices only.)  Configure the physical source and des-
            tination address for IP tunnel interfaces (gif(4)).  The argu-
            ments src_addr and dest_addr are interpreted as the outer
            source/destination for the encapsulating IPv4/IPv6 header.
