During the lwip initialisation in a RTOS environment is called function
tcpip_init() that creates tcp-ip task.

Unfortunately the return type is "void" so there is no information to caller
that the task was created.

I would suggest set the return value to "sys_thread_t" because the function
that really creates task(sys_thread_new) returns "sys_thread_t".

The prototype:
sys_thread_t tcpip_init(void (* tcpip_init_done)(void *), void *arg);
The body:
tcpip_init(void (* initfunc)(void *), void *arg){
return sys_thread_new(TCPIP_THREAD_NAME, tcpip_thread, NULL,
