40-100GbE IP Core Counts Certain Malformed Packets - 40-100GbE IP Core Counts Certain Malformed Packets Description If the 40-100GbE IP core receives a packet with a terminate character but without the proper preamble bytes, it increments the FCS error count in the CNTR_RX_FCS register at offset 0x2B8. In addition, if the packet is a runt, the IP core increments the runt count in the CNTR_RX_RUNT register at offset 0x2B6. Resolution This issue has no workaround. Be aware that malformed packets might be counted by the CNTR_RX_FCS and CNTR_RX_RUNT counters in versions 14.0 and later of the 40-100GbE IP core.
