What is the actual issue here? LSO should just be programmable UD fragmentation. It should be indistinguishable from a user app sending multiple send WRs to the UD QP. Surely it doesn't have anything to do with the underlying wire protocol? That said, I haven't seen anything talking about how to program the segmentation behavior (presumably it is assuming IP datagrams or something?). It is absolutely necessary to specify the segmentation method that the HW is going to use, there is lots of variety there.
