Agreed. The issue I was seeing was:

./tests/shell/stat_bpf_counters.sh: line 14: <not + <not / 10 : syntax
error: operand expected (error token is "<not + <not / 10 ")

but that syntax error is caused by running the test within a
hypervisor. I'll resend the patch set with this one dropped.

Thanks,
Ian
