Thanks.

I believe the problem is that rte_eth_link_get_nowait() in 
app_ports_check_link() is a no-wait version of rte_eth_link_get() (which 
is used in testpmd), the former won't cause up to 9sec stall in the 
process as the latter, but may not get up-to-date link status of the port.

Could you try, instead of using 1sec delay before 
app_ports_check_link(), but to replace rte_eth_link_get_nowait() to 
rte_eth_link_get(), and tell me if it works?
I suppose this should be a more reliable step to guarantee that you get 
the actual link status.

Regards,
Fan
