LogiCORE 10-Gigabit Ethernet MAC v8.6 - Invalid XGMII data transmitted after core is released from reset


After the core is released from reset and the DCM has locked, invalid data is sent out on XGMII_TXD for a couple clock cycles.


The invalid data transmitted is like a remote fault, except that the bytes/nibbles have been swapped on the XGMII_TXD, but not on XGMII_TXC. During the invalid sequence:  

XGMII_TXD is "9C0000019C000001" and XGMII_TXC is "00010001" 


This issue only occurs directly after the reset. This is scheduled to be fixed in the next release of the core.
