selftests/bpf/test_netcnt failed on i386 - ibbpf: failed to create map (name: 'percpu_netcnt'): Invalid argument

[Naresh Kamboju]

Newly added test case bpf test_netcnt failed on i386 and qemu_i386 on
mainline and -next kernel.
Here we are running i386 kernel on x86_64 device.
Pass on x86_64, arm64 and arm.

Am i missing any pre required Kconfigs ?

Hi Naresh!

Thank you for the report, I'll take a look.

Based on the results you've linked, it looks like there are many
failed bpf tests, so I can assume there is one or more shared problems.

Thanks!
