This field selects which LID data needs to be transmitted first according to its priority
set in the field WEIGHT in
when non-satisfied status information is received in the FIFO status channel.
0: The egress server scheduler schedules the LIDs in the calendar to be serviced in
a two-priority round robin according to the starving, hungry and satisfied status of
each LID. A starving status sets the LID priority high, a hungry status sets the prior-
ity low.
1: The egress server schedules the LIDs with hungry or starving status to be ser-
viced in a two-priority round robin scheme mode according to a fixed priority
scheme. The status values of hungry and starving received in the egress status cal-
endar are merged into a single non-satisfied status. The priority of the LID can be
set in the WEIGHT field in the
