[j-nsp] v6-in-v4 tunnels without tunnel PIC?

[Phil Rosenthal]

interfaces {
     ipip {
         unit 101 {
             description "IPv6 Tunnel to (blah)";
             tunnel {
                 source 1.2.3.4;
                 destination 5.6.7.8;
             }
             family inet6 {
                 address 2001:d00d:b00b::babe/126;
             }
         }
     }
}

Requires no tunnel services card -- I have no idea of the performance 
characteristics of this, I have been unable to accurately test.
