> After rte_flow_shared_action_* API was replaced with
> rte_flow_action_handle_* API, one input parameter of the update
> interface was also changed. A generic pointer was used instead of the
> "const struct rte_flow_action *" pointer.
> 
> In the entrance of mlx5 PMD callback for update, the validation is
> called for all indirect actions. But for conntrack type, the pointer
> is no longer with rte_flow_action pointer type and it will cause an
> incorrect casting and error.
> 
> The content for updating should only be validated when needed. It
> should skip the validation in the entrance. Right now, the content
> was already added before updating the hardware by WQE. So the type
> of the indirect action should be checked before calling the action
> validate function.
> 
> When creating a new conntrack object, the validation is still needed
> since all the content will be used to update the hardware context.
