I moved in to ethtool because the PSE drivers does not need it anymore.
I can keep it in pse.h.

Do you prefer the other way around, ethtool.h pulls in pse.h?
Several structure are used in ethtool, PSE core and even drivers at the same
time so I don't have much choice. Or, is it preferable to add a new header?
