Due to the ready latency of the eCPRI Intel® FPGA IP's mac_source_ready is 3 clock cycles, you may observe the mac_source_sop and mac_source_valid are asserted after the mac_source_ready is de-asserted.

Why does the eCPRI Intel® FPGA IP assert mac_source_sop and mac_source_valid after the mac_source_ready is de-asserted?
Description
Workaround/Fix
This is an expected behavior of the IP.
