Pull rdma updates from Jason Gunthorpe: "This is significantly bug fixes and general cleanups. The noteworthy new features are fairly small: - XRC support for HNS and improves RQ operations - Bug fixes and updates for hns, mlx5, bnxt_re, hfi1, i40iw, rxe, siw and qib - Quite a few general cleanups on spelling, error handling, static checker detections, etc - Increase the number of device ports supported beyond 255. High port count software switches now exist - Several bug fixes for rtrs - mlx5 Device Memory support for host controlled atomics - Report SRQ tables through to rdma-tool" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma: (145 commits) IB/qib: Remove redundant assignment to ret RDMA/nldev: Add copy-on-fork attribute to get sys command RDMA/bnxt_re: Fix a double free in bnxt_qplib_alloc_res RDMA/siw: Fix a use after free in siw_alloc_mr IB/hfi1: Remove redundant variable rcd RDMA/nldev: Add QP numbers to SRQ information RDMA/nldev: Return SRQ information RDMA/restrack: Add support to get resource tracking for SRQ RDMA/nldev: Return context information RDMA/core: Add CM to restrack after successful attachment to a device RDMA/cma: Skip device which doesn't support CM RDMA/rxe: Fix a bug in rxe_fill_ip_info() RDMA/mlx5: Expose private query port RDMA/mlx4: Remove an unused variable RDMA/mlx5: Fix type assignment for ICM DM IB/mlx5: Set right RoCE l3 type and roce version while deleting GID RDMA/i40iw: Fix error unwinding when i40iw_hmc_sd_one fails RDMA/cxgb4: add missing qpid increment IB/ipoib: Remove unnecessary struct declaration RDMA/bnxt_re: Get rid of custom module reference counting ...

net/mlx5: E-Switch, Prepare to return total vports from eswitch struct

2021-04-24T07:58:43+00:00

Total vports are already stored during eswitch initialization. Instead of calculating everytime, read directly from eswitch. Additionally, host PF's SF vport information is available using QUERY_HCA_CAP command. It is not available through HCA_CAP of the eswitch manager PF. Hence, this patch prepares the return total eswitch vport count from the existing eswitch struct. This further helps to keep eswitch port counting macros and logic within eswitch.

net/mlx5: E-Switch, Return eswitch max ports when eswitch is supported

2021-04-24T07:58:40+00:00

mlx5_eswitch_get_total_vports() doesn't honor MLX5_ESWICH Kconfig flag. When MLX5_ESWITCH is disabled, FS layer continues to initialize eswitch specific ACL namespaces. Instead, start honoring MLX5_ESWITCH flag and perform vport specific initialization only when vport count is non zero.

net/mlx5: DR, Add support for isolate_vl_tc QP

2021-04-20T03:17:46+00:00

When using SW steering, rule insertion rate depends on the RDMA RC QP performance used for writing to the ICM. During stress this QP is competing on the HW resources with all the other QPs that are used to send data. To protect SW steering QP's performance in such cases, we set this QP to use isolated VL. The VL number is reserved by FW and is not exposed to the driver. Support for this QP on isolated VL exists only when both force-loopback and isolate_vl_tc capabilities are set.

net/mlx5: DR, Add support for force-loopback QP

2021-04-20T03:17:43+00:00

When supported by the device, SW steering RoCE RC QP that is used to write/read to/from ICM will be created with force-loopback attribute. Such QP doesn't require GID index upon creation. Signed-off-by: Erez Shitrit Signed-off-by: Yevgeny Kliteynik Signed-off-by: Saeed Mahameed

net/mlx5: mlx5_ifc updates for flex parser

2021-04-20T03:17:22+00:00

Added the required definitions for supporting more protocols by flex parsers (GTP-U, Geneve TLV options), and for using the right flex parser that was configured for this protocol. Signed-off-by: Yevgeny Kliteynik Signed-off-by: Saeed Mahameed

net/mlx5e: RX, Add checks for calculated Striding RQ attributes

2021-04-20T03:17:09+00:00

Striding RQ attributes below are mutually dependent. An unaware change to one might take the others out of the valid range derived by the HW caps: - The MPWQE size in bytes - The number of strides in a MPWQE - The stride size Add checks to verify they are valid and comply to the HW spec and SW assumptions/requirements. This is not a fix, no particular issue exists today. Signed-off-by: Tariq Toukan Signed-off-by: Saeed Mahameed

net/mlx5: Add register layout to support extended link state

2021-04-16T18:48:25+00:00

Add needed structure layouts and defines for pddr register (Port Diagnostics Database Register) and the troublshooting page. This will be used to get extended link state from the monitor opcode bits. Signed-off-by: Moshe Tal Signed-off-by: Saeed Mahameed

Vport number is 16-bit field in hardware. Make it u16. Move location of vport in the structure so that it reduces a hole in the structure. Signed-off-by: Parav Pandit Signed-off-by: Saeed Mahameed
