Clarify text on how to calculate the length in bytes of the `ExtLen` field #14

Closed nicorusti closed 3 months ago

nicorusti commented 3 months ago

Explain how to calculate the length in bytes of the ExtLen field in the SCION Hop-by-Hop/End-to-End Options header (extension header of a SCION path header).

   *  ExtLen: Unsigned 8-bit integer.  The value of this field is
      computed as the length of the complete Hop-by-Hop/End-to-End
      Options header in multiples of 4-bytes minus 1.

Reference that this is similar to IPv6.
