I don't intend to push this to upstream kernel but I think we should
keep it for ofed since for older kernels it provides better performance.

We have a few critical bugs in ofed which I will address first and in
the background I'll push the fixes first and then the other patches. I
hope to get more of them to 2.6.26 and the rest will wait for 2.6.27.
