Hardware/Dell/D6000 Universal Dock

Displaylink Graphic Driver

The Displaylink entry shows all the steps in getting the graphics part of the Universal Dock / Docking Station up and running.

Enabling IPv6

So there seems to be an issue in the kernel drivers which makes Ethernet Multicast not working with this docking station (bug report and patches here). Somehow these patches or workarounds never got upstream, but with this code snippet you can include the patches easily inside your configuration.nix if you put the patches in a subdirectory for instance linux_kernel_cdc_ncm_patches:

{
  ...
  boot.kernelPatches = lib.singleton {
    name = "enable-d6000";
    patch = [
      ./linux_kernel_cdc_ncm_patches/0001-Hook-into-usbnet_change_mtu-respecting-usbnet-driver.patch
      ./linux_kernel_cdc_ncm_patches/0002-Admit-multicast-traffic.patch
    ];
  };
  ...
}
