Hello,

I have been trying to test a sample AF_XDP program, but I have been
experiencing some issues.
After building the sample code
https://github.com/torvalds/linux/tree/master/samples/bpf,
when running the xdpsock binary, I get the errors
"libbpf: failed to create map (name: 'xsks_map'): Invalid argument"
"libbpf: failed to load object './xdpsock_kern.o"

I tried to figure out the cause of the error but all I know is that it
occurs at line 910 with the function
call "bpf_prog_load_xattr(&prog_load_attr, &obj, &prog_fd)".

Please I would like to inquire what could be a possible for this error.

which kernel version are you running?
