.The `ip=IF_NAME:off` flag now disables both `IPv4` and `IPv6` and saves unexpected delays
Previously, setting the `ip=IF_NAME:off` flag in the kernel only disabled `IPv4` on the network interface. Consequently, the NetworkManager was trying to fetch the `IPv6` details and was causing unexpected delays if `IPv6` details were not found.
With this update, the `ip=IF_NAME:off` flag now disables both `IPv4` and `IPv6`. As a result, it avoids unexpected delays. However, users from 'ip=IP4::GW::IFACE:none' and relied on having `IPv6` connectivity can use 'ip=IP4::GW::IFACE:link6' or 'ip=IP4::GW::IFACE:auto6' to enable IPv6 connectivity again.

The fix for this bug reverts the change that was done for bug 1848943. We agreed that the new behavior makes more sense. I think we should document the change somewhere and perhaps reach out to the reporter of bug 1848943 to explain how to change the command line. Merged upstream https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/commit/3093a0073b6f578da1a52ee6f44d666e1c254afd. this is a change in behavior and needs to be highlighted in the release notes of 8.4. See also bug 1909213 which is about this change. Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
