Ethernet - all packets over 32 dropped

I have setup ethernet communication using the xps_ll_temac on a virtex 5 and am using the lwip tcpip stack. Everything works fine when running the provided iperf application, but when I run my own slightly modified code, it sends exactly 32 packets every time and drops the rest. Ive tried changing the number of udp_pcbs, pbufs and memory for pbufs all of which did nothing. Has anyone encountered a problem like this? Any ideas what could be causing this? Thanks

Try to increase the buffer size for tx and rx (C_TEMAC0_TXFIFO, C_TEMAC0_RXFIFO).
