net/mlx5e: SHAMPO, reduce TIR indication

2022-03-16T13:26:45Z

[ Upstream commit 99a2b9be077ae3a5d97fbf5f7782e0f2e9812978 ] SHAMPO is an RQ / WQ feature, an indication was added to the TIR in the first place to enforce suitability between connected TIR and RQ, this enforcement does not exist in current the Firmware implementation and was redundant in the first place.

net/mlx5: E-Switch, Fix resetting of encap mode when entering switchdev

2021-11-16T20:20:19Z

E-Switch encap mode is relevant only when in switchdev mode. The RDMA driver can query the encap configuration via mlx5_eswitch_get_encap_mode(). Make sure it returns the currently used mode and not the set one. This reverts the cited commit which reset the encap mode on entering switchdev and fixes the original issue properly.

net/mlx5: Allow skipping counter refresh on creation

2021-10-29T20:53:28Z

CT creates a counter for each CT rule, and for each such counter, fs_counters tries to queue mlx5_fc_stats_work() work again via mod_delayed_work(0) call to refresh all counters. This call has a large performance impact when reaching high insertion rate and accounts for ~8% of the insertion time when using software steering. Allow skipping the refresh of all counters during counter creation. Change CT to use this refresh skipping for it's counters.

net/mlx5e: Add handle SHAMPO cqe support

2021-10-27T02:30:40Z

This patch adds the new CQE SHAMPO fields: - flush: indicates that we must close the current session and pass the SKB to the network stack. - match: indicates that the current packet matches the oppened session, the packet will be merge into the current SKB. - header_size: the size of the packet headers that written into the headers buffer. - header_entry_index: the entry index in the headers buffer. - data_offset: packets data offset in the WQE. Also new cqe handler is added to handle SHAMPO packets: - The new handler uses CQE SHAMPO fields to build the SKB. CQE's Flush and match fields are not used in this patch, packets are not merged in this patch. Signed-off-by: Khalid Manaa Reviewed-by: Tariq Toukan Signed-off-by: Saeed Mahameed

net/mlx5e: Add support to klm_umr_wqe

2021-10-27T02:30:39Z

This commit adds the needed definitions for using the klm_umr_wqe. UMR stands for user-mode memory registration, is a mechanism to alter address translation properties of MKEY by posting WorkQueueElement aka WQE on send queue. MKEY stands for memory key, MKEY are used to describe a region in memory that can be later used by HW. KLM stands for {Key, Length, MemVa}, KLM_MKEY is indirect MKEY that enables to map multiple memory spaces with different sizes in unified MKEY. klm_umr_wqe is a UMR that use to update a KLM_MKEY. SHAMPO feature uses KLM_MKEY for memory registration of his header buffer. Signed-off-by: Ben Ben-Ishay Reviewed-by: Tariq Toukan Signed-off-by: Saeed Mahameed

net/mlx5e: Rename TIR lro functions to TIR packet merge functions

2021-10-27T02:30:39Z

This series introduces new packet merge type, therefore rename lro functions to packet merge to support the new merge type: - Generalize + rename mlx5e_build_tir_ctx_lro to mlx5e_build_tir_ctx_packet_merge. - Rename mlx5e_modify_tirs_lro to mlx5e_modify_tirs_packet_merge. - Rename lro bit in mlx5_ifc_modify_tir_bitmask_bits to packet_merge. - Rename lro_en in mlx5e_params to packet_merge_type type and combine packet_merge params into one struct mlx5e_packet_merge_param.

net/mlx5: Add SHAMPO caps, HW bits and enumerations

2021-10-27T02:30:39Z

This commit adds SHAMPO bit to hca_cap and SHAMPO capabilities structure, SHAMPO related HW spec hardware fields and enumerations. SHAMPO stands for: split headers and merge payload offload. SHAMPO new fields: WQ: - headers_mkey: mkey that represents the headers buffer, where the packets headers will be written by the HW. - shampo_enable: flag to verify if the WQ supports SHAMPO feature. - log_reservation_size: the log of the reservation size where the data of the packet will be written by the HW. - log_max_num_of_packets_per_reservation: log of the maximum number of packets that can be written to the same reservation. - log_headers_entry_size: log of the header entry size of the headers buffer. - log_headers_buffer_entry_num: log of the entries number of the headers buffer. RQ: - shampo_no_match_alignment_granularity: the HW alignment granularity in case the received packet doesn't match the current session. - shampo_match_criteria_type: the type of match criteria. - reservation_timeout: the maximum time that the HW will hold the reservation. mlx5_ifc_shampo_cap_bits, the capabilities of the SHAMPO feature: - shampo_log_max_reservation_size: the maximum allowed value of the field WQ.log_reservation_size. - log_reservation_size: the minimum allowed value of the field WQ.log_reservation_size. - shampo_min_mss_size: the minimum payload size of packet that can open a new session or be merged to a session. - shampo_max_log_headers_entry_size: the maximum allowed value of the field WQ.log_headers_entry_size Signed-off-by: Ben Ben-Ishay Reviewed-by: Tariq Toukan Signed-off-by: Saeed Mahameed
