Hi David,

I have one more question. When I was working on new patch, I just want 
to make sure what we are doing.

For the "if-else" case of enable_lcore_rx_distributor, we will reduce 
the line of codes; but I am not sure about that change. Because the type 
of the variable is bool and we are using arithmetic operation on that 
variable. I think it is a little bit harder for people to understand 
operation. Am I right? I can suggest one more solution. We may change 
the data type to "unsigned int" or Is it okay to leave as before?
