I don't think is it a good idea to modify xdp_redirect_map this way. The xdp_redirect_map is used for comparative benchmarking and mentioned+used in scientific articles. As far as I can see, this change will default slowdown xdp_redirect_map performance, right? -- Best regards, Jesper Dangaard Brouer MSc.CS, Principal Kernel Engineer at Red Hat LinkedIn: http://www.linkedin.com/in/brouer
