Doc Text:
.The Networking System Role no longer fails to set a DNS search domain if IPv6 is disabled Previously, the `nm_connection_verify()` function of the `libnm` library did not ignore the DNS search domain if the IPv6 protocol was disabled. As a consequence, when you used the Networking RHEL System Role and set `dns_search` together with `ipv6_disabled: true`, the System Role failed with the following error: ---- nm-connection-error-quark: ipv6.dns-search: this property is not allowed for 'method=ignore' (7) ---- With this update, the `nm_connection_verify()` function ignores the DNS search domain if IPv6 is disabled. As a consequence, you can use `dns_search` as expected, even if IPv6 is disabled.

Description Wen Liang 2021-09-16 11:49:55 UTC 
Description of problem:

When `dns_search` is specified and ipv6 method is ignore, when called with nm provider, the role relys on 
libnm function`nm_connection_verify()` to validate a configuration, as a result, libnm will emit the error message "nm-connection-error-quark: ipv6.dns-search: this property is not allowed for 'method=ignore' (7)". 
To properly handle this in the network role, the role should silently ignore such dns search setting for ipv6.
