34 * @brief RDMA client driver interface
36 * Functions to interface with the RDMA client driver, for enabling RMDA
37 * functionality for the ice driver.
42 * The ice device driver provides the rmda_di_if.m interface methods, while
43 * the client RDMA driver provides the irdma_if.m interface methods as an
46 * The initial connection between drivers is done via the RDMA client driver
58 * @brief global RDMA driver state
60 * Contains global state the driver uses to connect to a client RDMA interface
61 * driver.
91 * @brief RDMA driver interface methods
93 * Kobject methods implementing the driver-side interface for the RDMA peer
95 * request from the driver.
97 * The client driver will then extend this kobject class with methods that the
98 * driver can request from the client.
109 /* Define ice_rdma_di class which will be extended by the iRDMA driver */
116 * Implements IRDMA_DI_RESET, called by the RDMA client driver to request
117 * a reset of an ice driver device.
125 /* Tell the base driver that RDMA is requesting a PFR */
128 /* XXX: Base driver will notify RDMA when it's done */
138 * Implements IRDMA_DI_MSIX_INIT, called by the RDMA client driver to

323 * ice_rdma_request_handler - handle requests incoming from RDMA driver
354 * to RDMA driver
356 * @dcbx_cfg: current DCB settings in ice driver
416 * Verify that the client RDMA driver provided a version that is compatible
417 * with the driver interface.
