1.1. Low Latency 40-Gbps Ethernet IP Core v16.1
|Enhanced malformed packet handling.
The IP core now ignores standard flow control pause packets if they are runt packets or have FCS errors. This change does not affect the IP core's handling of priority-based flow control packets.
|The IP core potentially exhibits a behavior change. If you turn on standard flow control, the IP core might not process some incoming pause packets that it would previously have processed. The IP core continues to forward or drop these packets according to the setting in the RX_PAUSE_FWD register at offset 0x706.||Change required for UNH compliance.|
|Added new option for strict SFD checking.
The IP provides a new parameter Enable strict SFD checking. If you turn on this parameter, the IP core checks the SFD and preamble bytes in all incoming packets for the following values:
