Containers

  1. Allow configuring a default MTU for all containers

    All container network interfaces ("vEthernet (Ethernet)") use MTU 1500 by default. There is no way to configure a default MTU other than 1500, despite Docker and Microsoft documentation which indicates that this should be possible: https://docs.microsoft.com/en-us/virtualization/windowscontainers/manage-docker/configure-docker-daemon, https://docs.docker.com/engine/reference/commandline/dockerd/#description.

    This is a huge pain point for users running on platforms that require an MTU less than 1500. The only solution at this time is to set the container interface's MTU first thing every time one runs a container, for every container.
