10-Gigabit Ethernet PCS/PMA and AXI 10G Ethernet - 10GBASE-KR - UltraScale GTH - Auto-Negotiation/Link Training can occasionally take extra time to complete


If you are using 10GBASE-KR with Auto-Negotiation/Link Training protocols on UltraScale GTHE3 devices, the Auto-Negotiation and Link Training can occasionally take a noticeable amount of time (2-6 seconds) to complete. 

It can sometimes take multiple restarts (initiated automatically by watchdog timers) for Auto-Negotiation and Link Training to complete.


This issue is currently under investigation.
