/**
 * @defgroup lwip_nosys Mainloop mode ("NO_SYS")
 * @ingroup lwip
 * Use this mode if you do not run an OS on your system. \#define NO_SYS to 1.
 * Feed incoming packets to netif->input(pbuf, netif) function from mainloop,
 * *not* *from* *interrupt* *context*. You can allocate a @ref pbuf in interrupt
 * context and put them into a queue which is processed from mainloop.\n
 * Call sys_check_timeouts() periodically in the mainloop.\n
 * Porting: implement all functions in @ref sys_time and @ref sys_prot.\n
 * You can only use @ref callbackstyle_api in this mode.\n
 * Sample code:\n
 * @verbinclude NO_SYS_SampleCode.c

/**
 * @defgroup lwip_os OS mode (TCPIP thread)
 * @ingroup lwip
 * Use this mode if you run an OS on your system. It is recommended to
 * use an RTOS that correctly handles priority inversion and
 * to use @ref LWIP_TCPIP_CORE_LOCKING.\n
 * Porting: implement all functions in @ref sys_layer.\n
 * You can use @ref callbackstyle_api together with \#define tcpip_callback,
 * and all @ref threadsafe_api.
