4.3.10. RX Throttling
The eCPRI Intel® FPGA IP doesn't support throttling on the RX side (from 25G Ethernet MAC to eCPRI). Packets from Ethernet MAC are continuously streamed out either to external-ST source interface or eCPRI IP source interface and you should allocate enough buffer to hold the packets.
