AF XDP-example operation not supported

[goodsollee]

Hi,

I'm trying to run AX_XDP-example code, but I can't run it. Even though I can load XDP kernel program to the network interface, it ends to show operation not supported in xsk_configure_socket.

Environment is as follows:
kernel: ubuntu 22.04
version: 6.8.0-49-generic
bpftool v7.4.0
using libbpf v1.4

I attach my logs:
bpf-examples/AF_XDP-example$ sudo taskset -c 2 ./xdpsock -i enp58s0 -l -N -B -b 256

Thanks in advance!
