Flow steering initialization is based on static tree which illustrates the flow steering tree when the driver is loaded. The initialization considers the max supported flow table level of the device, a minimum of 2 kernel flow tables(vlan and mac) are required to have kernel flow table functionality. The tree structures when the driver is loaded: root_namespace(receive nic) | priority-0 (kernel priority) | namespace(kernel namespace) | priority-0 (flow tables priority) In the following patches, When the EN driver will use the flow steering API, it create two flow tables and their flow groups under priority-0(flow tables priority).
