Push/pop of headers is listed as on of the missing features here: https://prototype-kernel.readthedocs.io/en/latest/networking/XDP/implementation/missing_features.html We can hopefully soon cross that of the list :-) Header push and pop desc: https://prototype-kernel.readthedocs.io/en/latest/networking/XDP/design/requirements.html#header-push-and-pop Thanks for working on this! :-))) -- Best regards, Jesper Dangaard Brouer MSc.CS, Principal Kernel Engineer at Red Hat LinkedIn: http://www.linkedin.com/in/brouer
