From: Leon Romanovsky <leonro@xxxxxxxxxxxx> >From Yishai: This series introduces vendor create and destroy flow methods on the uverbs flow object by using the KABI infra-structure. It's done in a way that enables the driver to get its specific device attributes in a raw data to match its underlay specification while still using the generic ib_flow object for cleanup and code sharing. In addition, a specific mlx5 matcher object and its create/destroy methods were introduced. This object matches the underlay flow steering mask specification and is used as part of mlx5 create flow input data. This series supports IB_QP/TIR as its flow steering destination as applicable today via the ib_create_flow API, however, it adds also an option to work with DEVX object which its destination can be both TIR and flow table. Few changes were done in the mlx5 core layer to support forward compatible for the device specification raw data and to support flow table when the DEVX destination is used. As part of this series the default IB destroy handler (i.e. uverbs_destroy_def_handler()) was exposed from IB core to be used by the drivers and existing code was refactored to use it.
