If XFRM makes use of gro_cells, it is time to move it in net/core, instead of inlining it. I can submit this trivial patch, of course. > I suspect we can do something similar for USB networking drivers. With some changes then, because gro_cells is per cpu at the moment, probably overkill for one USB networking driver.
