> 
> This patch set will remove the flow rules cache and move to the
> non-cached mode for both DV and Verbs mode.
> 
> In the device closing stage, all the software resources for flows
> created will be freed and corresponding hardware resources will be
> released. Then the total cost of the memory will be reduced and the
> behavior of mlx5 PMD will comply fully with the ethdev API
> expectations.
> 
> After closing a device, all the flow rules stored in application
> layer will no longer be valid anymore. Application should synchronize
> the database and do not try to destory any rule on this device.
> And after a device restarting, all the needed flow rules should be
> reinserted via the create routine in the rte_flow lib.

> v3 Changes:
>     Refactor the device flow related structures to support non-cached
>     mode for both Verbs and DV flows.
> v4 Changes:
>     Fix the code style warning for stdbool type and a typo in the
>     code line comments.
