The logic of this loop is wrong.
The port ids may be not contiguous.
Look at RTE_ETH_FOREACH_DEV* for such iteration.

The function rte_eth_dev_count is deprecated.
It should be noticed when compiling.
On more comment, I think such wrong implementation is existing
in many examples:
% git grep -l 'check_all_ports_link_status(.*num'
app/test/test_pmd_perf.c
examples/link_status_interrupt/main.c
examples/load_balancer/init.c
examples/multi_process/client_server_mp/mp_server/init.c
examples/multi_process/symmetric_mp/main.c
examples/server_node_efd/server/init.c
