Error: low_latency_40g_eth_top.alt_e40_0: 40GBASE No FLOW CONTROL, PRIORITY QUEUE should set as 1 - Error: low_latency_40g_eth_top.alt_e40_0: 40GBASE No FLOW CONTROL, PRIORITY QUEUE should set as 1 Description You may see this error in the Intel® Quartus® Prime Pro software version 18.1 when upgrading the Low Latency 40G IP from Intel® Quartus® Prime Pro software version 18.0 using a priority queue of 8 with flow control. Resolution To work around this problem you need to change the priority queue to 1 without flow control in the Low Latency 40G IP since a priority queue of 8 with flow control is not supported.
