When programming the sockets API you're not
going to check for ACK packets....

The socket layer should call the tcp_write(),
tcp_output() and tcp_timers() to handle egress
TCP segments and TCP ACKs from it's tcpip_thread.

When programming the raw-API you're responsible
for calling tcp_write, tcp_output running
the TCP timers at the required intervals.
