Corresponding source code
There is still a TCP_WND macro as the default initialization window size, then a tcp_wnd_size() function is provided to specifically set the new initial window size of the new TCP connection, tcp_wnd_size() provides a safe range judgment, and even different netif can set different initial windows size.
