It sounds like you are using linked pbufs incorrectly. Try using pbuf_take().

[field #14]      Original Submission: We have used the UDP Ethernet protocol LWIP203 for bare metal coding of cyclone V SoC. We have faced the issue that we couldn’t transmit more than 80 bytes in the packet. But we can able receive 1024 data per packet.
