Hi All,

New to lwIP, have been searching the list and docs about this but found
no answer. What is the behaviour of netconn_recv when received data
spans multiple netbufs? Will each call to netconn_recv return each
subsequent buffer,

Each call will return one netbuf (containing one chain of the underlying pbufs). You then retrieve the data from the netbuf using the usual functions netbuf_data()/netbuf_next().
