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
