Initial firewall config causes temporary packet loss
Due to ordering of firewall rule/policy configuration, all incoming packets may be dropped during firewall configuration, until its completion. This creates a race condition where this packet loss could result in manifest application failure, causing the initial unlock to fail. In order to avoid this packet loss, this update adds ordering dependencies to ensure the default policies are applied only after the common platform firewall rules.
