    OK. I'll try different things and document them for the
    linuxperf site so that others can learn from it. I'm
    also downloading a new netbase package since ifconfig 1.46
    doesn't seem to know about txqueuelen :)

    Btw, are the net gurus working on improving the worst-case
    default behaviour of the Linux networking code? In this
    case workarounds are needed to get regular work done, this
    just isn't the Right Thing :(
