The *_init() functions should be called during boot. sys_init() should be 
called first, and then mem_init(), memp_init(), and pbuf_init() in any order. 
When all those are called, ip_init(), udp_init() and tcp_init() should be 
called.

It will cause problems for connections that are running when the change is 
made. But other than that, it should work.
