/**
|
|
* @brief TCPIP adapter library
|
|
*
|
|
* The aim of this adapter is to provide an abstract layer upon TCPIP stack.
|
|
* With this layer, switch to other TCPIP stack is possible and easy in esp-idf.
|
|
*
|
|
* If users want to use other TCPIP stack, all those functions should be implemented
|
|
* by using the specific APIs of that stack. The macros in CONFIG_TCPIP_LWIP should be
|
|
* re-defined.
|
|
*
|
|
* tcpip_adapter_init should be called in the start of app_main for only once.
|
|
*
|
|
* Currently most adapter APIs are called in event_default_handlers.c.
|
|
*
|
|
* We recommend users only use set/get IP APIs, DHCP server/client APIs,
|
|
* get free station list APIs in application side. Other APIs are used in esp-idf internal,
|
|
* otherwise the state maybe wrong.
|
|
*
|
|
* TODO: ipv6 support will be added, use menuconfig to disable CONFIG_TCPIP_LWIP
