[Bug 1875927] Re: add support for phys_port_name attribute in Xenial/16.04LTS

[Eric Desrochers]

** Description changed:

  It has been brought to my attention that systemd in Xenial/16.04LTS
  doesn't have support for phys_port_name[0] attribute.
  
  The support has been first introduced in systemd version "232" via:
  https://github.com/systemd/systemd/commit/4887b656c22af059d4e833de7b56544f24951184
  https://github.com/systemd/systemd/pull/4506
  
  Bionic and late have the necessary bits ( systemd >232), but not Xenial
  (229)[1]
+ 
+ Support for "phys_port_name" has been first introduced in the kernel
+ with v4.1[2]
