L2TP: Add option for custom fib id for outgoing encapsulated packets
If a custom fib ID is used (different from ~0), the associated
fib is used to forward outgoing encapsulated packets.
Otherwise, the fib used is the same as for any packet
received on the original RX interface (L2TP does not modify RX interface index).
