Hi, I'm a bit new to lwip.
When I transfer data both side with network switch, it work fine. When I'm using hub, I can see avialable tcp_sndbuf going down to zero and never coming back up to TCP_SND_BUF size. I'm checking tcp_sndbuf before tcp_write and I called tcp_output() When both TX and RX, I can see it happened more quickly than RX only. What would cause that tcp_sndbuf draining? i'm using lwip 1.3.0. thanks..
