    I don't think you will get better than 90% performance, but if you do
    please let me know! I have written another e100 driver, in an attempt
    to transmit and receive small packets at the maximum possible rate.

    In tests, it would not even transmit at 100% small packets on our 82558.
    (I didn't do that test on our 82559).

    Ah well..

    Curiously, I found that turning on the interrupt saving microcode slows
    the cards down. It lessens the load on the mainboard CPU, but I am not
    using interrupts, I'm polling the memory descriptors 100% of the time,
    so the interrupt saving microcode shouldn't affect the mainboard CPU.
    It does lower the throughput though.
