If the MRMAC is operating at
100GE data rate, the AXI4-Stream interface can be further
configured in either Non-Segmented or Segmented mode. For all other data rates, the AXI4-Stream can only operate in non-segmented mode.
Configuration of 100GE port to operate in segmented versus non-segmented AXI4-Stream mode is through the ctl_axi_cfg_N field of the MODE_REG register, as listed in the previous
table.
