  Flags: 8 bits

  (None assigned yet)

  Option Vector: 24 bits

  A set of bit fields giving values for the reservation options. If new options are added in the future, corresponding fields in the option vector will be assigned from the least-significant end. If a node does not recognize a style ID, it may interpret as much of the option vector as it can, ignoring new fields that may have been defined.

  The option vector bits are assigned (from the left) as follows:

  19 bits: Reserved

  2 bits: Sharing control

  00b: Reserved

  01b: Distinct reservations

  10b: Shared reservations

  11b: Reserved

  3 bits: Sender selection control

  000b: Reserved

  001b: Wildcard

  010b: Explicit

  011b - 111b: Reserved

  The low order bits of the option vector are determined by the style, as follows:

                WF 10001b
                FF 01010b
                SE 10010b
