Weird question: Should there be a reason for me to expect bpf_redirect to fail when redirecting, in XDP, to the egress of an xdpgeneric device? I'm redirecting from an XDP program on a tap device, out the igb eno1 to the Internet (and fixing MAC addresses). I can redirect to other tap devices, but not to eno1. I was going to try with bpf_redirect_map, but I'm having tooling trouble there (I can't get iproute2 to load a BPF object file with a pinned DEVMAP; it complains that the flags don't match). But for my purposes, bpf_redirect would be fine. (My testbed is 5.6, for whatever that's worth). This mailing list is fantastic and you are all excellent. Thanks whether or not anyone has any thoughts. --- Thomas H. Ptacek
