---Problem Description---
qeth on a DPM-managed IBM Z machine does not obtain its MAC Address for L2 OSD interfaces from the OSA Network Adapter. Instead it uses a random MAC Address.

This causes connectivity issues in setups where a reliable & pre-determined MAC Address is required - ie. when doing network configuration via DHCP.

---uname output---
Ubuntu 18.04 / vmlinuz-4.15.0-101-generic

Machine Type = IBM z14 GA2

---Debugger---
A debugger is not configured

---Steps to Reproduce---
 - Bring up a qeth L2 OSD interface in DPM-managed LPAR.
- Inspect the interface's MAC Address. It should be the same as displayed in the DPM Panels.

Stack trace output:
 no

Oops output:
 no

System Dump Info:
  The system is not configured to capture a system dump.

-Attach sysctl -a output output to the bug.

Backport of "s390/qeth: improve fallback to random MAC address"

Backport of "s390/qeth: utilize virtual MAC for Layer2 OSD devices"
