AR# 53444
Ethernet 1000BASE-X PCS/PMA or SGMII v11.5 - After disabling Auto-Negotiation, Auto-Negotiation sequences might still be transmitted if core has not yet gained synchronization
Description
If using the Ethernet 1000BASE-X PCS/PMA or SGMII core v11.5 and earlier, after disabling Auto-Negotiation, Auto-Negotiation sequences might still be transmitted if the core has not yet gained synchronization.
Solution
This will not keep synchronization from completing.
This is resolved in the Vivado 2013.1, Ethernet 1000BASE-X PCS/PMA or SGMII v12.0 release of the core.
