We know that it is recommended that ASLR be turned off so that the mappings
across primary and secondary remain the same.

Does ASLR need to be turned off system-wide, or DPDK-processes wide? Could
we use setarch/personality to disable ASLR for just the DPDK process and
leave it enabled for the rest of the system? Any experience to say if that
would work or not?
