link check is done for primary process for the ports
which are given in the port mask and not the complete
set of ports.

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
