I think this would change the device name for existing devices, right? If so, that doesn't seem appropriate for an SRU, as it could break existing users that expect their device names to be consistent...

"phys_port_name" indicates the interface physical port name within the NIC. [Test Case] Check that udev (systemd-udevd) provides the phys_port_name property Tests should be done on both kernel versions: v4.4 and v4.15 [Regression Potential] Risk: Low * This piece of code is already in place in Bionic (systemd) and late. AFAICT, nothing has been reported since then with regards to this feature. * phys_port_name kernel support has been introduced in v4.1. Xenial supported kernel are : v4.4 and v4.15 (HWE). * If a regression arise, it will most likely be limited to the "Ethernet switch device driver model (switchdev)" reported by: rocker, mlxsw, broadcom, ...
