This is C99 feature and we tend to not use it BUT,

Thomas, David,

In the past there were c89/c90/ansi code in DPDK, but as far as I can 
see no more left.

Is there anything that prevents us using C99 features, like variable in 
the for loop, I think it is usefull that it reduces the scope and makes 
code more readable, etc...
