DP83816 is not working with high servers like intel xeon

Other Parts Discussed in Thread: DP83816, DP83815

Hi,

one of my customer is developed a network card with DP83816 (macphyter) but facing issues when connected to high servers.  issues like two places with intel xeon server. One place no response from our card , one place pci loopback test fails

AN-1287 DP83815 MacPHYTER and DP83816 MacPHYTER-II High Data Rate Stress
Testing(Document)

we have found an above application note which shows under some conditions.  There seems to be an issue with receive FIFO updates which may cause corrupted data to be transferred to the host w/o any FIFO error conditions in the interrupt status register.The document also shows there is a means to detect the issue and I have instrumented the code and see that I can detect the condition. 

Please see said document and let us know if there is a fix for this?

Is there a newer revision of the chip where this issue has been fixed.

 

Regards

Nandish
