Hello,

First, I have disabled the IPv6-Protocol in YaST2, because the DNS-resolving goes in trouble. Thunderbird and other network tools have troubles with DHCP (IPv4 + IPv6).

I go to YaST2 and disable IPv6.
Steps to reproduce:
1. Network Devices -> Network Settings
2. Global Settings -> IPv6 Protocol Settings -> disable "Enable IPv6"

I found these repeated lines in /var/log/messages:

Jul  7 01:20:45 linux dhclient: XMT: Solicit on eth0, interval 113830ms.
Jul  7 01:20:45 linux dhclient: send_packet6: Cannot assign requested address
Jul  7 01:20:45 linux dhclient: dhc6: send_packet6() sent -1 of 54 bytes

But I found out in "Overview" from "Network Settings" that the assigned Ethernet-Card has still activate the DHCP4 *AND* DHCP6-Client.

I assume, if I disable the IPv6-Protocol, then the DHCP setting from assigned Ethernet-Card should be switching to "DHCP version 4 only" and should NOT set to "DHCP both version 4 and 6"!!!

I would call it a design error in YaST2 (Network) and should be fixed.

Reproducible: Always

Steps to Reproduce:
1. run YaST2
2. Network Devices -> Network Settings
3. Global Settings -> IPv6 Protocol Settings -> disable "Enable IPv6"
4. look at "Overview" and go into any Ethernet-Card setting and check DHCP setting.

Actual Results:  
Assigned Ethernet-Card still used DHCP6, if IPv6 is disabled.


Expected Results:  
Assigned Ethernet-Card should use DHCP4, if IPv6 is disabled.
