The Flags field within RSVP RECORD_ROUTE IPv4_Subobject is decoded incorrectly.
Wireshark thinks that 0x10 bit represents Node-ID, but actually the Node-ID is
encoded by bit 0x20 (per RFC 4561). As a result the Wireshark incorrectly
reports Node-ID subobject as non-Node-ID. Look at attached dump for RRO IPv4
10.0.4.0.
