BGP Tunnel Encapsulation Attribute Sub-TLVs

Reference
[RFC-ietf-idr-tunnel-encaps-22]
Note
If the Sub-TLV Type is in the range from 0 to 127 inclusive, the
Sub-TLV Length field contains one octet.  If the Sub-TLV Type is
in the range from 128-255 inclusive, the Sub-TLV Length field
contains two octets.
