> The driver should start out with a reasonable number of descriptors that can
> prevent drops due to a CPU being in a power management state.
> Change the default number of descriptors to 2048.
> The user can always change the value at runtime. Transmit descriptor counts
> are not modified because they don't need to change due to the speed of the
> interface, or for power managed CPUs, but the code is simplified to a fixed
> value for the transmit default.
