mlx5: bpf_xdp_metadata_rx_hash add xdp rss hash type

2023-04-13T18:15:10Z

Update API for bpf_xdp_metadata_rx_hash() with arg for xdp rss hash type via mapping table. The mlx5 hardware can also identify and RSS hash IPSEC. This indicate hash includes SPI (Security Parameters Index) as part of IPSEC hash. Extend xdp core enum xdp_rss_hash_type with IPSEC hash type.

net/mlx5e: Propagate an internal event in case uplink netdev changes

2023-02-09T04:40:57Z

Whenever uplink netdev is set/cleared, propagate newly introduced event to inform notifier blocks netdev was added/removed. Move the set() helper to core.c from header, introduce clear() and netdev_added_event_replay() helpers. The last one is going to be called from rdma driver, so export it.

net/mlx5: E-Switch, properly handle ingress tagged packets on VST

2022-12-28T19:38:49Z

Fix SRIOV VST mode behavior to insert cvlan when a guest tag is already present in the frame. Previous VST mode behavior was to drop packets or override existing tag, depending on the device version. In this patch we fix this behavior by correctly building the HW steering rule with a push vlan action, or for older devices we ask the FW to stack the vlan when a vlan is already present.

net/mlx5: Use generic definition for UMR KLM alignment

2022-11-30T05:09:44Z

MLX5_UMR_KLM_ALIGNMENT is in units of number of entries, while MLX5_UMR_MTT_ALIGNMENT (generalized and renamed to MLX5_UMR_FLEX_ALIGNMENT) is in byte units. This is misleading and confusing. Replace this KLM definition with one based on the generic definition. Signed-off-by: Tariq Toukan Reviewed-by: Gal Pressman Signed-off-by: Saeed Mahameed

net/mlx5e: Add padding when needed in UMR WQEs

2022-11-30T05:09:42Z

Per the device spec, MTTs/KLMs list in a UMR WQE must be aligned to 64B. Per our SW design, the MTT/KLMs list would need alignment only if it's too small, for example on PPC when PAGE_SIZE is 64KB, and only 4 pages are needed to cover a MPWQE of size 256KB. Padding, if needed, is taken into account when calculating the UMR WQE fields (ds_cnt and xlt_octowords), however no entries are provided, instead garbage is passed. No real harm though, as these parts act as gaps between the RX MPWQEs and not used by any of them. Hence, in practice, device does not try to write any incoming packet to them. Still, prefer providing clean padding marking the end of the list, and do not map garbage into the RQ memory region. Signed-off-by: Tariq Toukan Reviewed-by: Gal Pressman Signed-off-by: Saeed Mahameed
