> The HWS non-template flow API is reusing some implementation of template
> API to unifiy code logic. So for each rule creation, a stub / temporary table is
> used in order to reuse the actions construction.
> 
> Since this is temporary and used only internally, there is no need to save the
> table permanently. Only parts of them are mandatory, so the allocation / free
> from the heap of RTE memory is a waste and causes a lot of overhead. By
> using the pre-allocated workspace and set the needed fields expliticly will save
> the overhead and help to speed up the rule insertion rate.
