When I configure a qeth OSA device, the installer asks for device type, device and protocol layer:

Please choose the type of your primary network interface that you will need for 
 
installing the Debian system (via NFS or HTTP). Only the listed devices are   
supported.  
Network device type:  
  1: ctc: Channel to Channel (CTC) or ESCON connection,      
  2: qeth: OSA-Express in QDIO mode / HiperSockets,      
  3: iucv: Inter-User Communication Vehicle - available for VM guests only,     
 
  4: virtio: KVM VirtIO,      
Prompt: '?' for help> 2
2  
  
Please select the OSA-Express QDIO / HiperSockets device.  
Device:  
  1: 0.0.f5f0-0.0.f5f1-0.0.f5f2  [*],  
Prompt: '?' for help, default=1> 1

By default OSA-Express cards use layer3 mode. In that mode LLC headers are   
removed from incoming IPv4 packets. Using the card in layer2 mode will make it
keep the MAC addresses of IPv4 packets.  
Use this device in layer2 mode?  
  1: Yes [*]  2: No  
Prompt: '?' for help, default=1> 

The last question experienced a change according to https://bugs.launchpad.net/ubuntu/+source/s390-netdevice/+bug/1526801
Layer2 is the default, which is correct, since the qeth driver uses layer2 as default as well.

However, the introductional text says: "By default OSA-Express cards use
layer3 mode."

And this is wrong and needs to be fixed. Correct wording is:

"By default OSA-Express cards use layer2 mode. In layer3 mode LLC headers are   
removed from incoming IPv4 packets. Using the card in layer2 mode will make it   
keep the MAC addresses of IPv4 packets."

Although LP 1526801 deals with this subject, it is different.
LP 1526801 is implemented and closed. Now the documentational part in the installer needs to follow that. Thus I recommend to treat this as a separate bug.
