       RTE SWX Extern objects and functions

       Extern object and extern function interfaces. The extern objects and extern functions provide the
       mechanisms to hook external functionality into the packet processing pipeline.

   typedefint(*rte_swx_extern_type_member_func_t)(void*object,void*mailbox)
       Extern object member function

       The mailbox is used to pass input arguments to the member function and retrieve the output results. The
       mailbox mechanism allows for multiple concurrent executions of the same member function for the same
       extern object.

       Multiple invocations of the same member function may be required in order for the associated operation to
       complete. The completion is flagged by a return value of 1, in which case the results are available in
       the mailbox; in case of a return value of 0, the operation is not yet completed, so the member function
       must be invoked again with exactly the same object and mailbox arguments.

       Parametersobject Extern object handle.
           mailbox Extern object mailbox.

       Returns
           0 when the operation is not yet completed, and 1 when the operation is completed. No other return
           values are allowed.
