[44net] encapsulated ipencap packets

In our tunnels, all traffic from a gateway should be encapsulated and should NOT contain an encapsulated ipencap packet. The ipip router at UCSD logs and discards these; I'm seeing such packets from gateways 77.138.34.39 85.234.252.133 86.161.255.194 185.58.225.84 which suggests that they have a routing misconfiguration. The operators of those gateways should examine their routing and encapsulation rules to see why this is happening. - Brian
