This is mainly because software/hardware > resources are allocated and prepared during the flow rule creation. > > In order to optimize the insertion rate, PMD may use some hints provided > by the application at the initialization phase. The rte_flow_configure() > function allows to pre-allocate all the needed resources beforehand. > These resources can be used at a later stage without costly allocations. > Every PMD may use only the subset of hints and ignore unused ones or > fail in case the requested configuration is not supported. > > The rte_flow_info_get() is available to retrieve the information about > supported pre-configurable resources. Both these functions must be called > before any other usage of the flow API engine. > > Signed-off-by: Alexander Kozyrev <akozy...@nvidia.com> > ---
