    Packet loss after idle

    flyduck

      I am using Mellanox ConnectX-3, and I see packet loss when the traffic surges after idle. It can handle all the traffic most of the time, but the packet drop happens only after the traffic was idle (tens or hundreds of packets) for some time being. I suspect the card or CPU was doing some kind of power save stuff. I have intel_idle.max_cstate set to 1. How can I avoid this kind of packet loss? Thank you.
