 *
 *  In present implementation, applications are able to access mesh stack directly without having to go through LwIP stack.
 *  Applications use esp_mesh_send() and esp_mesh_recv() to send and receive messages over the mesh network.
- *  In mesh stack design, normal devices don't require LwIP stack. But since IDF hasn't supported system without initializing LwIP stack yet,
- *  applications still need to do LwIP initialization and two more things are required to be done
- *  (1) stop DHCP server on softAP interface by default
- *  (2) stop DHCP client on station interface by default.
- *  Examples:
- *  tcpip_adapter_init();
- *  tcpip_adapter_dhcps_stop(TCPIP_ADAPTER_IF_AP)；
- *  tcpip_adapter_dhcpc_stop(TCPIP_ADAPTER_IF_STA)；
+ *  In mesh stack design, normal devices don't require LwIP stack, but if any of these devices could be promoted to a root node in runtime,
+ *  (due to automatic or manual topology reconfiguration) the TCP/IP stack should be initialized (for the root code to access external IP network)
 *
 *  Over the mesh network, only the root is able to access external IP network.
 *  In application mesh event handler, once a device becomes a root, start DHCP client immediately whether DHCP is chosen.

 ESP-NETIF is an intermediary between an IO driver and a network stack, connecting packet data path between these two. As that it provides a set of interfaces for attaching a driver to ESP-NETIF object (runtime) and configuring a network stack (compile time). In addition to that a set of API is provided to control network interface lifecycle and its TCP/IP properties. As an overview, the ESP-NETIF public interface could be divided into these 6 groups:
