Description Gris Ge 2018-10-29 07:44:38 UTC 
Description of problem:

nmstate would like to support disabling IPv6 like we did for IPv4.
To achieve that it could be ideal if NetworkManager could provide
support of NM_SETTING_IP6_CONFIG_METHOD_DISABLED.

Version-Release number of selected component (if applicable):
NetworkManager-1.14.0-1.el8.x86_64

How reproducible:
100%

Steps to Reproduce:
1. 
2.
3.

Looks good to me.

Perhaps nm_ip6_config_create_setting() could generate method=disabled if it sees ipv6.disabled sysctl set. (I'm not sure; it's not a merge blocker if tests pass)

Pushed a commit to do that.

Tested on NetworkManager-1.20.0-0.3.el8, ipv6 disabling works well including after reboot.
