* net/mlx5: SRIOV core code refactoringMohamad Haj Yahia2016-09-103-129/+101
| | | | | | | | | | | | | | | Simplify the code and makes it look modular and symmetric. Split sriov enable/disable to two levels: device level and pci level. When user enable/disable sriov (via sriov_configure driver callback) we will enable/disable both device and pci sriov. When driver load/unload we will enable/disable (on demand) only device sriov while keeping the PCI sriov enabled for next driver load. On internal/pci error, VFs will be kept enabled on PCI and the reset is done only in device level.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The driver RQ has two possible configurations: striding RQ and non-striding RQ. Until this patch, the driver always reported the number of hardware WQEs (ring descriptors). For non striding RQ configuration, this was OK since we have one WQE per pending packet For striding RQ, multiple packets can fit into one WQE. For better user experience we normalize the rx_pending parameter (size of wqe/mtu) as the average ring size in case of striding RQ. Fixes: 461017cb006a ('net/mlx5e: Support RX multi-packet WQE ...')

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of asking the firmware to flush the SQ (Send Queue) via asynchronous completions when moved to error, we handle SQ flush manually (mlx5e_free_tx_descs) same as we did when SQ flush got timed out or on tx_timeout. This will reduce SQs flush time and speedup interface down procedure. Moved mlx5e_free_tx_descs to the end of en_tx.c for tx critical code locality.

| * net/mlx5e: Limit UMR length to the device's limitationSaeed Mahameed2016-08-284-16/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ConnectX-4 UMR (User Memory Region) MTT translation table offset in WQE is limited to U16_MAX, before this patch we ignored that limitation and requested the maximum possible UMR translation length that the netdev might need (MAX channels * MAX pages per channel). In case of a system with #cores > 32 and when linear WQE allocation fails, falling back to using UMR WQEs will cause the RQ (Receive Queue) to get stuck. Here we limit UMR length to min(U16_MAX, max required pages) (while considering the required alignments) on driver load, by default U16_MAX is sufficient since the default RX rings value guarantees that we are in range, dynamically (on set_ringparam/set_channels) we will check if the new required UMR length (num mtts) is still in range, if not, fail the request.

Plus to those ten patches, we add two patches that unifies mlx5 commands execution interface and improve the driver log messages in that area. From Hadar and Ilya, added the needed hardware bits and infrastructure for minimum inline headers setting and encap/decap commands and capabilities, needed for E-Switch offloads. This series applies on top latest net-next and rdma/master, and smoothly merges with the latest "Mellanox 100G mlx5 fixes 2016-08-16" series already applied into net branch. ==================== Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now as all commands use mlx5 ifc interface, instead of doing two calls for executing a command we embed command status checking into mlx5_cmd_exec to simplify the interface. Also we do here some cleanup for redundant software structures (inbox/outbox) and functions and improved command failure output.

| * | {net,IB}/mlx5: Modify QP commands via mlx5 ifcSaeed Mahameed2016-08-171-9/+115
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Prior to this patch we assumed that modify QP commands have the same layout. In ConnectX-4 for each QP transition there is a specific command and their layout can vary. e.g: 2err/2rst commands don't have QP context in their layout and before this patch we posted the QP context in those commands. Fortunately the FW only checks the suffix of the commands and executes them, while ignoring all invalid data sent after the valid command layout. This patch removes mlx5_modify_qp_mbox_in and changes mlx5_core_qp_modify to receive the required transition and QP context with opt_param_mask if needed. This way the caller is not required to provide the command inbox layout and it will be generated automatically. mlx5_core_qp_modify will generate the command inbox/outbox layouts according to the requested transition and will fill the requested parameters.
