Can the 40G/100G Ethernet Intel® FPGA IP achieve 100% bandwidth in all configurations?

Environment

    Quartus® II Subscription Edition
    Ethernet
BUILT IN - ARTICLE INTRO SECOND COMPONENT
Description

No, the TX of 40G/100G Ethernet Intel® FPGA IP cannot achieve 100% bandwidth for some packet sizes if the preamble pass-through or the TX CRC pass-through options are enabled. The RX can reach 100% bandwidth regardless of options.

Resolution

Disable both the preamble pass-through option and the TX CRC pass-through option.

Another workaround is to migrate to the Low Latency 40G/100G Ethernet Intel® FPGA IP.
