Why does the Ethernet 10G MAC Intel® FPGA IP's XGMII interface output last few bytes of data with unknown state in simulation?

Description

You may encounter above problem if the csr_reset signal of Ethernet 10G MAC Intel® FPGA IP did not toggle once after the start of simulation.

Workaround/Fix

To work around this problem, the csr_reset signal needs to be toggled once at the beginning of simulation.
