Title:
  qeth: utilize virtual MAC for Layer2 OSD devices

Status in Ubuntu on IBM z Systems:
  Incomplete
Status in linux package in Ubuntu:
  Incomplete

Bug description:
  ---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.
