"Mode" in the AAL parameters IE has been eliminated by UNI 3.1

Appendix B of draft-ietf-ipatm-sig-02 indicates:

   1. AAL parameter

   Values for maximum SDU size may range from one (not zero) to 64K.

   A 'mode' field is an allowable field in UNI 3.0. Nevertheless, this
   'mode' field SHOULD be omitted from the AAL Parameters IE and MUST be
   ignored by the destination endsystem.
