- *
- *   where:
- *
- *   o  Next Header: 8-bit selector.  Identifies the type of header
- *      immediately following the SRH.
- *
- *   o  Hdr Ext Len: 8-bit unsigned integer, is the length of the SRH
- *      header in 8-octet units, not including the first 8 octets.
- *
- *   o  Routing Type: TBD, to be assigned by IANA (suggested value: 4).
- *
- *   o  Segments Left.  Defined in [RFC2460], it contains the index, in
- *      the Segment List, of the next segment to inspect.  Segments Left
- *      is decremented at each segment.
- *
- *   o  First Segment: contains the index, in the Segment List, of the
- *      first segment of the path which is in fact the last element of the
- *      Segment List.
- *
- *   o  Flags: 8 bits of flags.  Following flags are defined:
- *
- *         0 1 2 3 4 5 6 7
- *        +-+-+-+-+-+-+-+-+
- *        |U|P|O|A|H|  U  |
- *        +-+-+-+-+-+-+-+-+
- *
- *        U: Unused and for future use.  SHOULD be unset on transmission
- *        and MUST be ignored on receipt.
- *
- *        P-flag: Protected flag.  Set when the packet has been rerouted
- *        through FRR mechanism by an SR endpoint node.
- *
- *        O-flag: OAM flag.  When set, it indicates that this packet is
- *        an operations and management (OAM) packet.
- *
- *        A-flag: Alert flag.  If present, it means important Type Length
- *        Value (TLV) objects are present.  See Section 3.1 for details
- *        on TLVs objects.
- *
- *        H-flag: HMAC flag.  If set, the HMAC TLV is present and is
- *        encoded as the last TLV of the SRH.  In other words, the last
- *        36 octets of the SRH represent the HMAC information.  See
- *        Section 3.1.5 for details on the HMAC TLV.
- *
- *   o  RESERVED: SHOULD be unset on transmission and MUST be ignored on
- *      receipt.
- *
- *   o  Segment List[n]: 128 bit IPv6 addresses representing the nth
- *      segment in the Segment List.  The Segment List is encoded starting
- *      from the last segment of the path.  I.e., the first element of the
- *      segment list (Segment List [0]) contains the last segment of the
- *      path while the last segment of the Segment List (Segment List[n])
- *      contains the first segment of the path.  The index contained in
- *      "Segments Left" identifies the current active segment.
- *
- *   o  Type Length Value (TLV) are described in Section 3.1.
