Looking at the log file, it seems like the xdp_helper in net/lib is not 
compiled so calling this helper from the test fails. There is similar 
failures where xdp_dummy.bpf.o in net/lib is not compiled either.

Error opening object 
/usr/src/perf_selftests-x86_64-rhel-9.4-kselftests-59dd07db92c166ca3947d2a1bf548d57b7f03316/tools/testing/selftests/net/lib/xdp_dummy.bpf.o: 
No such file or directory

I'm still not sure what the root cause is. On my machine, these files 
are compiled correctly.

Thanks,
Quang Minh.
