I have said before I do not understand why the dmabuf paradigm is not sufficient for both device memory and host memory. A less than ideal control path to put hostmem in a dmabuf wrapper vs extra checks and changes in the datapath. The former should always be preferred. I also do not understand why the ifq cache and overloading xdp functions have stuck around; I always thought both were added by Jonathan to simplify kernel ports during early POC days.
