I have a comment about the following change:

+		error = fprintf(nmfile, "\n[ipv4]\n");
+		if (error < 0)
+			goto setval_error;
+
+		if (new_val->dhcp_enabled) {
+			error = kvp_write_file(nmfile, "method", "", "auto");
+			if (error < 0)
+				goto setval_error;
+		} else {
+			error = kvp_write_file(nmfile, "method", "", "manual");
+			if (error < 0)
+				goto setval_error;
+		}

I think the method equally would apply for ipv6 as it applies for ipv4. 
We can use https://www.golinuxcloud.com/nmcli-command-examples-cheatsheet-centos-rhel/#18_Disable_IPv6_Address_for_ethernet_connection_IPV6INIT as a reference. 
So setting the method should be common to both ipv4 and ipv6.
