Description Gris Ge 2019-08-13 09:04:13 UTC

Description of problem:

With IPv6 disabled on certain interface, the rollback will re-enable the IPv6.


Version-Release number of selected component (if applicable):
nmstate-0.0.8-6.el8

How reproducible:

Steps to Reproduce:
1. Create file `eth1_disable_ipv6.yml` with:

---
interfaces:
  - name: eth1
    type: ethernet
    state: up
    ipv6:
      enabled: false

2. Create `eth1_rollback.yml` with

---
interfaces:
  - name: eth1
    mtu: 1000000

3. sudo nmstatectl set eth1_disable_ipv6.yml && sudo nmstatectl set eth1_rollback.yml

4. ip -6 addr show eth1

Actual results:

IPv6 re-enabled.

Expected results:
