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