Due to a problem in the Quartus® Prime Pro Edition Software version 23.4, incorrectly-sized packets will be transmitted from the multi-port Agilex™ 7 F-Tile variants of the Ethernet Subsystem FPGA IP when both the Dynamic Reconfiguration parameter is enabled and the Client Interface parameter is set to MAC Segmented. This problem will affect all dynamically reconfigurable ports ranging from 50GbE to 400GbE.
There is no workaround for this problem.
This problem has been fixed starting in version 24.1 of the Quartus® Prime Pro Edition Software.
