    Set rings rx/tx to maximum that supports hardware

    All recent versions of the chipset have 4096, but the driver doesn't
    autodetect this. Increasing the number of descriptors can improve
    performance dramatically on some hosts.

    This is also the case with Intel 10GE NICs - the driver defaults to 256
    descriptors each for Rx and Tx, even if the hardware supports 4096.
