It is difficult to design a algorithm which considers the hardware
of the platform, network traffic, and even the USB behavior to
dynamically modify the setting. I don't think I have the capability
to do it.

Besides, I don't wish to modify the setting by ethtool when re-loading
the driver or rebooting every time.

Excuse me. Why is it not accepted for being a Kconfig parameter.
It let the manufactuers of some platforms, especially the embedded
system, could tune their performance. Should I give up this patch?
