Max IB immediate data size is 2^28 (MAX_IMM_PAYL_BITS) and the minimum chunk size is 4096 (2^12). Therefore the maximum sess_queue_depth is 65536 (2^16). Link: https://lore.kernel.org/r/20210528113018.52290-6-jinpu.wang@ionos.comSigned-off-by:

Both the PKEY and GID tables in an HCA can hold in the order of hundreds entries. Reading them is expensive. Partly because the API for retrieving them only returns a single entry at a time. Further, on certain implementations, e.g., CX-3, the VFs are paravirtualized in this respect and have to rely on the PF driver to perform the read. This again demands VF to PF communication. IB Core's cache is refreshed on all events. Hence, filter the refresh of the PKEY and GID caches based on the event received being IB_EVENT_PKEY_CHANGE and IB_EVENT_GID_CHANGE respectively.

Define .init_cmd_priv and .exit_cmd_priv callback functions in struct scsi_host_template. Set .cmd_size such that the SCSI core allocates per-command private data. Use scsi_cmd_priv() to access that private data. Remove the req_ring pointer from struct srp_rdma_ch since it is no longer necessary. Convert srp_alloc_req_data() and srp_free_req_data() into functions that initialize one instance of the SRP-private command data. This is a micro-optimization since this patch removes several pointer dereferences from the hot path. Note: due to commit e73a5e8e ("scsi: core: Only return started requests from scsi_host_find_tag()"), it is no longer necessary to protect the completion path against duplicate responses.

The transition of the QP state from SQD to RTS is allowed by the IB specification. The hardware also supports that, but it is not implemented in mlx5_ib. This commit adds SQD2RTS command to the modify QP in mlx5_ib to support the missing feature. The feature is required by the signature pipelining API that will be added to rdma-core.
