      option-code          OPTION_IA_TA (4). 

      option-len           4 + length of IA_TA-options field. 

      IAID                 The unique identifier for this IA_TA; the
                           IAID must be unique among the identifiers
                           for all of this client's IA_TAs.  The number
                           space for IA_TA IAIDs is separate from the
                           number space for IA_NA IAIDs. 

      IA_TA-options        Options associated with this IA_TA.
