When using the Intel® Stratix® 10, H-tile Hard IP for Ethernet Intel® FPGA IP, oversized frame stripping can cause invalid frames to be presented to user logic.

Description

When the H-tile Hard IP for Ethernet Intel® FPGA IP RX MAC receives frame size >= 65536, and enforce_max_frame_size is enabled, the frame output from RX MAC to user logic will be truncated to the frame size specified by max_rx_frame_size setting. A second invalid frame will output from RX MAC to user logic starting from byte-65536 to end of the super large frame.

Resolution

No workaround or fix is available for this errata problem.

This problem is scheduled to be fixed in a future release of the Intel® Quartus® Prime Software.
