[Bug 1644355] Re: udev netdev naming does not work with mellanox switches

[Martin Pitt]

Can you please add a test case? I. e. how does the naming currently
look, and how is it supposed to look with the patch?

Title:
  udev netdev naming does not work with mellanox switches

Status in systemd package in Ubuntu:
  Fix Released
Status in systemd source package in Yakkety:
  Incomplete

Bug description:
  The current packaged systemd for Yakkety does not have the Mellanox
  netdev udev naming set for systemd patch installed
  (https://github.com/systemd/systemd/commit/4887b656c22). The current
  version for zesty does. I installed the ppa for this on to my Yakkety
  switch and rebooted and the devices are properly named.

  SRU TEST CASE:
    * (To be filled out by Luke)

  REGRESSION POTENTIAL:
  This changes the network device names for an unknown set of devices (those which have a "phys_port_name" sysfs attribute), which can lead to unbootable/inaccessible existing systems. @Luke: Is this only being used by Mellanox drivers in yakkety's kernels? Which other drivers expose this?
