'eth_dev_info_get_print_err()' already fail, but it may not be very
clear to the user,
OK to print a failure log, but setting 'rec_nb_pkts = 0;' as above also
will generate an error message that also may be confusing to the user.

What about print an explicit error message for the
'eth_dev_info_get_print_err()' failed case?
