Bug description:
  Impact]

   * On virtualization hosts disable GRO and LRO, otherwise, with
     receive offload on, the guests will receive packets that are
     larger than the MTU. This can cause issues in certain scenarios, 
     e.g. when the guest is a VPN server that needs to forward the
     (inner) packet onward.

  [Test Plan]

   * The feature does not exist right now.

  [Where problems could occur]

   * The settings exist since systemd-232 which means Bionic and up can use
     this feature

  [Original Description]

  https://www.freedesktop.org/software/systemd/man/systemd.link.html has
  a number of [Link] options which I need to use for a flaky network
  card (TCPSegmentationOffload, TCP6SegmentationOffload,
  GenericSegmentationOffload, GenericReceiveOffload,
  LargeReceiveOffload) which are not exposed via netplan.
