Initial link_status64 value should be 0 (memory allocated with
rte_zmalloc_socket()) and lio_dev_stop() sets it to 0. So there should be no
need to set zero here.
Are you observing cases this value is not zero? Can you please add more
information to commit log about what/how you are observing and what is the
result of it?
