Random ip_id generation also breaks MANET multicast as it's currently
specified -- the ip_id field gets used for histogram based duplicate
packet detection. However, after my inveigling, Fred Templin at Boeing
brought encapsulation back into the proposal on the table.
So some way to turn this stuff off on a per-interface basis is probably
going to be needed later on for mobile stuff...
