* net/mlx5e: RX, Always prefer Linear SKB configurationTariq Toukan2018-06-021-3/+10
| | | | | | | | | | | Prefer the linear SKB configuration of Legacy RQ over the non-linear one of Striding RQ. This implies that ConnectX-4 LX now uses legacy RQ by default, as it does not support the linear configuration of Striding RQ.

* net/mlx5e: RX, Enhance legacy Receive Queue memory schemeTariq Toukan2018-06-023-127/+362
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Enhance the memory scheme of the legacy RQ, such that only order-0 pages are used. Whenever possible, prefer using a linear SKB, and build it wrapping the WQE buffer. Otherwise (for example, jumbo frames on x86), use non-linear SKB, with as many frags as needed. In this case, multiple WQE scatter entries are used, up to a maximum of 4 frags and 10KB of MTU. This implied to remove support of HW LRO in legacy RQ, as it would require large number of page allocations and scatter entries per WQE on archs with PAGE_SIZE = 4KB, yielding bad performance. In earlier patches, we guaranteed that all completions are in-order, and that we use a cyclic WQ. This creates an oppurtunity for a performance optimization: The mapping between a "struct mlx5e_dma_info", and the WQEs (struct mlx5e_wqe_frag_info) pointing to it, is constant across different cycles of a WQ. This allows initializing the mapping in the time of RQ creation, and not handle it in datapath. A struct mlx5e_dma_info that is shared between different WQEs is allocated by the first WQE, and freed by the last one. This implies an important requirement: WQEs that share the same struct mlx5e_dma_info must be posted within the same NAPI. Otherwise, upon completion, struct mlx5e_wqe_frag_info would mistakenly point to the new struct mlx5e_dma_info, not the one that was posted (and the HW wrote to). This bulking requirement is actually good also for performance reasons, hence we extend the bulk beyong the minimal requirement above. With this memory scheme, the RQs memory footprint is reduce by a factor of 2 on x86, and by a factor of 32 on PowerPC. Same factors apply for the number of pages in a GRO session. Performance tests: ConnectX-4, single core, single RX ring, default MTU. x86: CPU: Intel(R) Xeon(R) CPU E5-2680 v3 @ 2.50GHz Packet rate (early drop in TC): no degradation TCP streams: ~5% improvement PowerPC: CPU: POWER8 (raw), altivec supported Packet rate (early drop in TC): 20% gain TCP streams: 25% gain Signed-off-by: Tariq Toukan <tariqt@mellanox.com> Signed-off-by: Saeed Mahameed <saeedm@mellanox.com>
* net/mlx5e: RX, Use cyclic WQ in legacy RQTariq Toukan2018-06-026-111/+161
| | | | | | | | | | | | | | | | | | Now that LRO is not supported for Legacy RQ, there is no source of out-of-order completions in the WQ, and we can use a cyclic one. This has multiple advantages: - reduces the WQE size (smaller PCI transactions). - lower overhead in datapath (no handling of 'next' pointers). - no reserved WQE for the WQ head (was need in linked-list). - allows using a constant map between frag and dma_info struct, in downstream patch. Performance tests: ConnectX-4, single core, single RX ring. Major gain in packet rate of single ring XDP drop. Bottleneck is shifted form HW (at 16Mpps) to SW (at 20Mpps).

* net/mlx5e: RX, Remove HW LRO support in legacy RQTariq Toukan2018-06-022-14/+26
| | | | | | | | | | | | | | | | | | Current LRO implementation in Legacy RQ uses high-order pages. In downstream patches of this series we complete the transition to using only order-0 pages in RX datapath (which was already done in Striding RQ). Unlike the more advanced Striding RQ, Legacy RQ does not make reuse of any non-consumed buffers of non-full LRO sessions, and combining it with order-0 pages has many performance drawbacks. Hence, here we totally remove LRO support in Legacy RQ. This guarantees having no out-of-order completions, which allows using a cyclic work queue (instead of a linked-list) in a downstream patch.

| | | | | | | | | | | | | | | | | | | | | | | | | | | As the mvpp2 driver is growing, move this driver to a dedicated directory and split it into several files. Since this driver has a lot of register defines and structure definitions, it can benefit from having all of this into a dedicated header file, named mvpp2.h. A good chunk of the mvpp2 code is dedicated to Header Parser handling, so we introduce mvpp2_prs.h where all Header Parser definitions are located, and mvpp2_prs.c containing the related code. In the same way, mvpp2_cls.h and mvpp2_cls.c are created to contain Classifier and RSS related code. The former 'mvpp2.c' file is renamed 'mvpp2_main.c' so that we can keep the driver binary named 'mvpp2'. This commit is only about spliting the driver into multiple files and doesn't introduce any new function, feature or fix besides removing 'static' keywords when needed.

| * net/mlx5e: Get the number of offloaded TC rules from the correct tableOr Gerlitz2018-05-302-4/+8
| | | | | | | | | | | | | | | | | | | | | | | | As we keep the offloaded TC rules for NIC and e-switch in two different places, make sure to return the number of offloaded flows according to the use-case and not blindly from the priv.

| * net/mlx5: FPGA, Call DMA unmap with the right sizeIlya Lesokhin2018-05-301-2/+1
| | | | | | | | | | | | | | | | | | | | | | When mlx5_fpga_conn_unmap_buf is called buf->sg[0].size should equal the actual buffer size, not the message size. Otherwise we will trigger the following dma debug warning "DMA-API: device driver frees DMA memory with different size" Fixes: 537a50574175 ('net/mlx5: FPGA, Add high-speed connection routines') Signed-off-by: Ilya Lesokhin <ilyal@mellanox.com> Signed-off-by: Saeed Mahameed <saeedm@mellanox.com>
