Why do you initialize variables then set then in the next statement.
Sure the compiler will optimize away the waste, but not good style.

You could skip the temporary variable here and just put cast in the memcpy.

We want to get rid of rte_memcpy(), only use it where it is performance 
sensitive
and variable size.
