You can use xdpdump to dump the packets from the XDP program before it gets redirected into the XSK: https://github.com/xdp-project/xdp-tools/tree/master/xdp-dump Doens't currently work on egress, but if/when we get a proper TX hook that should be doable as well. Wiring up XSK to AF_PACKET sounds a bit nonsensical: XSK is already a transport to userspace, why would you need a second one? -Toke
