Hi, I don't know how I can update in Xilinx to LWIP 1.32.
- MEM_SIZE 524288 - TCP_SND_QUEUELEN 16 * TCP_SND_BUF/TCP_MSS - MEMP_N_PBUF 16 These are the debug information: The packet with the length of 1518 Bytes doesn't go out. With wireshark I don't see it. After a timeout the connection will be closed.
