Hello, Is there any way to disable flow control for NICs using the r8169 driver? It would be really valuable in the following (sadly very common) scenario: * r8169 gigabit NIC on the server * unmanaged gigabit switch that supports flow control negotiation * 100Mbps clients E.g. in LTSP labs, the server can send data at ~900Mbps with flow control off, but with flow control on the bandwidth drops to ~90Mbps. Detailed explanation of the problem: http://virtualthreads.blogspot.com/2006/02/beware-ethernet-flow-control.html If the current code doesn't support it, would it be possible to add a module parameter for this?
