Hi, Thomas Monjalon&Ferruh Yigit and others

     I'm analyzing multiprocess with eal. I have some questions I'd like 
to ask you.

Firstly, After the rte_eal_init() command is executed, the master and 
slave processes are started successfully.

and traffic is continuously sent using the tester.If you run the kill -9 
command to stop the slave process, restart the re-process, and start 
packet receiving and sending,

how to ensure that the eal resource of the slave process is cleaned up?

Second, how to invoke the remove function to clear probe resources of 
the slave process after the slave process exits?

Finally, I found out why the rte_eal_cleanup call was not unregistered 
mp action after the process exited.

I look forward to your response.
