> 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.
