Add two new parameters: max_burst_sz and typical_pkt_size (both in bytes) to rate limit configurations. max_burst_sz: The device will schedule bursts of packets for an SQ connected to this rate, smaller than or equal to this value. Value 0x0 indicates packet bursts will be limited to the device defaults. This field should be used if bursts of packets must be strictly kept under a certain value. typical_pkt_size: When the rate limit is intended for a stream of similar packets, stating the typical packet size can improve the accuracy of the rate limiter. The expected packet size will be the same for all SQs associated with the same rate limit index. Ethernet driver is updated according to this change, but these two parameters will be kept as 0 due to lacking of proper way to get the configurations from user space which requires to change ndo_set_tx_maxrate interface.

What is going on here is a bit subtle, in the kernel there is no problem because the struct is copied using copy_from_user, so it can safely have an 8 byte alignment, however in userspace it must be constructed by concatenation with the ib_uverbs_alloc_pd_resp struct. This is due to the required memory layout to execute the command. Since ibv_uverbs_alloc_pd_resp is only 4 bytes long, this causes misalignment, and the user space will experience an unexpected padding. Currently it works around this via pointer maths. Make everything more robust by having the compiler reduce the alignment of the struct to 4. The userspace has assertions to ensure this works properly in all situations.

Resolving route for RoCE for a path record is needed only for the received CM requests. Therefore, (a) ib_init_ah_attr_from_path() is refactored first to isolate the code of resolving route. (b) Setting dlid, path bits is not needed for RoCE. Additionally ah attribute initialization is done from the path record entry, so it is better to refer to path record entry type for different link layer instead of ah attribute type while initializing ah attribute itself.

Implement RDMA nldev netlink interface to get detailed CM_ID information. Because cm_id's are attached to rdma devices in various work queue contexts, the pid and task information at restrak_add() time is sometimes not useful. For example, an nvme/f host connection cm_id ends up being bound to a device in a work queue context and the resulting pid at attach time no longer exists after connection setup. So instead we mark all cm_id's created via the rdma_ucm as "user", and all others as "kernel". This required tweaking the restrack code a little. It also required wrapping some rdma_cm functions to allow passing the module name string.

In order to add a context to the FPGA, we need to get both the software transform context (which includes the keys, etc) and the source/destination IPs (which are included in the steering rule). Therefore, we register new set of firmware like commands for the FPGA. Each time a rule is added, the steering core infrastructure calls the FPGA command layer. If the rule is intended for the FPGA, it combines the IPs information with the software transformation context and creates the respective hardware transform. Afterwards, it calls the standard steering command layer. Signed-off-by: NAviad Yehezkel <aviadye@mellanox.com> Signed-off-by: NSaeed Mahameed <saeedm@mellanox.com>

The current code has one layer that executed FPGA commands and the Ethernet part directly used this code. Since downstream patches introduces support for IPSec in mlx5_ib, we need to provide some abstractions. This patch refactors the accel code into one layer that creates a software IPSec transformation and another one which creates the actual hardware context. The internal command implementation is now hidden in the FPGA core layer. The code also adds the ability to share FPGA hardware contexts. If two contexts are the same, only a reference count is taken. Signed-off-by: NAviad Yehezkel <aviadye@mellanox.com> Signed-off-by: NSaeed Mahameed <saeedm@mellanox.com>

Current hardware decrypts and authenticates incoming ESP packets. Subsequently, the software extracts the nexthdr field, truncates the trailer and adjusts csum accordingly. With this patch and a capable device, the trailer is being removed by the hardware and the nexthdr field is conveyed via PET. This way we avoid both the need to access the trailer (cache miss) and to compute its relative checksum, which significantly improve the performance. Experiment shows that trailer removal improves the performance by 2Gbps, (netperf). Both forwarding and host-to-host configurations.

The has_tag member will indicate whether a tag action was specified in flow specification. A flow tag 0 = MLX5_FS_DEFAULT_FLOW_TAG is assumed a valid flow tag that is currently used by mlx5 RDMA driver, whereas in HW flow_tag = 0 means that the user doesn't care about flow_tag. HW always provide a flow_tag = 0 if all flow tags requested on a specific flow are 0. So we need a way (in the driver) to differentiate between a user really requesting flow_tag = 0 and a user who does not care, in order to be able to report conflicting flow tags on a specific flow.
