I want to use the netconn_api for my app , but I have a question :
I need to optimize the bandwith due to high latency connection
(intercontinental) , so I'll send big packets 
(about 5KB by 5KB) . Because the systeme doe not havo much memory I would 
send the data with NETCONN_NOCOPY . 
So I have to be sure the full packet was ACK to be able to use the netbuf
again . 
How can I know if the full packet was ACKed byt the remote peer ? 

Thanks in advance
