> This patch replaces C99-style flexible arrays in struct rte_flow_action_rss
> and struct rte_flow_item_raw with standard pointers to the same data.
> 
> They proved difficult to use in the field (e.g. no possibility of static
> initialization) and unsuitable for C++ applications.
> 
> Affected PMDs and examples are updated accordingly.
> 
> This breaks ABI compatibility for the following public functions:
> 
> - rte_flow_copy()
> - rte_flow_create()
> - rte_flow_query()
> - rte_flow_validate()

There are almost as much insertions as deletions.
So it's probably not a bad move.
