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

[Eric Desrochers]

Public bug reported:

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]
