tcp_recved() is not a callback, it's an API function you must call to
signal that you consumed some data from the TCP window.
It's usually called from the receive callback, but not necessarily.
Trex7 can add the pbuf to a linked list, and call it outside the
callback, provided that he has exclusive access to lwIP core: not using
an OS nor calling lwIP from interrupts
