I am using imx6q based custom board. When i run iperf server on imx6q i see around 90% packet drops at 1000Mbps UDP traffic. I came across post pointing to The i.MX6DQ Errata document states in Errata ERR004512 that the maximum performance “is limited to 470 Mbps (total for Tx and Rx)”. So are there any patches available to enable pause frame mode and increase the throughput. I am using linux kernel 3.14.52.
