Sagi Grimberg 5587856c96 IB/iser: Introduce fast memory registration model (FRWR) ... Newer HCAs and Virtual functions may not support FMRs but rather a fast registration model, which we call FRWR - "Fast Registration Work Requests". This model was introduced in 00f7ec36c ("RDMA/core: Add memory management extensions support") and works when the IB device supports the IB_DEVICE_MEM_MGT_EXTENSIONS capability. Upon creating the iser device iser will test whether the HCA supports FMRs. If no support for FMRs, check if IB_DEVICE_MEM_MGT_EXTENSIONS is supported and assign function pointers that handle fast registration and allocation of appropriate resources (fast_reg descriptors). Registration is done using posting IB_WR_FAST_REG_MR to the QP and invalidations using posting IB_WR_LOCAL_INV.
