Title:
  expose layer2, hwchecksumming, buffer_count network-hardware options

Status in nplan package in Ubuntu:
  Expired

Bug description:
  Some network HW configurations like wake-on-lan, mtu and such are already exposed.
  Certainly not all that ethtool can handle, and none of the attributes that not even ethtool can handle.

  In the System z world there are a few HW attributes that are rather common to be changed.
  In particular:
  - layer2 (required to be set correctly for networking to work at all)
  - hwchecksumming (performance)
  - buffer_count (performance)

  Look at chzdev of package s390-tools for more background and how it is
  currently done via udev rules.

  For s390x - If implemented IBM would have to work with us in a way that the passing of the ephemeral state netplan provides to a system later on that gets (re-)configured via chzdev works as expected.
  But I guess for now the bug is for the "lower network-HW options" in general and not only s390x.
