Why do I see packet corruption with the Low Latency 10G MAC non-1588 example design?

Description

Due to a problem in the Intel® Quartus® software version 15.1, you may see packet corruption when using the example design generated in the IP Parameter editor.  Only the following variants of the Low Latency 10G MAC are affected:  

1. 10M/100M/1G/10G Ethernet (without 1588)
2. 1G/10G Ethernet (without 1588)

Resolution

There is no workaround for this problem.

This problem is fixed starting in Quartus software version 15.1.1.
