It got a packet loss on iperf test. WRLinux-5.0.1 seems send a invaild packet to the peer.
Please see the packet capture.

[Linux Host/Ubuntu 12.04]
1) iperf -s -u -i 1
2) Wireshark(*1)
   *1: Wireshark's Filter: 
   !udp && !tcp && !arp && !igmp && !icmpv6 && !icmp && !ip

1) build malloc_loop.c
2) ./
3) iperf -c -u -i 1 -b 90M -t 9999999

==> Wireshark got the attached packet capture.
    The packet data seems u-boot code(address is 0).
