Small UDP packet performance

    Currently, I find that my PPC 405EP board has some problem about the
throughput of small UDP packet (188 bytes). The throughput is just only
~0.01%. However, for large packet, say 1K, the throughput is very good. It
is more than 50%. Is it a problem of PPC Linux, ethernet driver or generic
Linux? Is there any way to tune it? Thanks.
