network_state should not change IPv6 state when not configured

[myllynen]

Using this definition against RHEL 8.8 systems which use NM and ifcfg files

    network_state:
      dns-resolver:
        config:
          server:
            - 1.1.1.1
      interfaces:
        - name: net0
          type: ethernet
          state: up
          ipv4:
            enabled: true
            auto-dns: false
            dhcp: true

changes IPV6_INIT=no to IPV6_INIT=yes on IPv4-only systems. On RHEL 9.2 systems which use NM and nmconnection files this does not happen, which is expected. The workaround is of course obvious but nevertheless network_state should not change anything outside of the provided configuration definition. Thanks.

@myllynen When not mentioned IPv6 config, nmstate copy from current status in kernel(not config of NM). Can you provide more detail on how to reproduce this problem?

[myllynen]

On the target system I have these sysctls in place:

$ cat /etc/sysctl.d/50-ipv6.conf
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1

And also IPV6_INIT=no in the corresponding ifcfg file. I configured these, updated the initramfs (just in case), rebooted and ip a showed no IPv6 enabled for any interface. After applying with a playbook the above I then see the ifcfg/IPV6_INIT change.

Is this enough for you to test/reproduce or would you need more info? Thanks.
