> Subject: [PATCH v2 4/4] net/mlx5: driver support for shared action
> 
> Implement shared action create/destroy/update/query. The current
> implementation support is limited to shared RSS action only. The shared RSS
> action create operation prepares hash RX queue objects for all supported
> permutations of the hash.  The shared RSS action update operation relies on
> functionality to modify hash RX queue introduced in one of the previous
> commits in this patch series.
> 
> Implement RSS shared action and handle shared RSS on flow apply and release.
> The lookup for hash RX queue object for RSS action is limited to the set of
> objects stored in the shared action itself and when handling shared RSS action.
> The lookup for hash RX queue object inside shared action is performed by hash
> only.
> 
> Current implementation limited to DV flow driver operations i.e. verbs flow
> driver operations doesn't support shared action.
