2021-10-27wcn36xx: Fix HT40 capability for 2Ghz bandLoic Poulain
All wcn36xx controllers are supposed to support HT40 (and SGI40), This doubles the maximum bitrate/throughput with compatible APs. Tested with wcn3620 & wcn3680B.

2021-10-27wcn36xx: Treat repeated BMPS entry fail as connection lossBryan O'Donoghue
On an open AP when you pull the plug on the AP, if we are not already in BMPS mode then the firmware will not generate a disconnection event. Instead we need to monitor for failure to enter BMPS and treat a string of failures as connection loss. Secure AP connections don't appear to demonstrate this behavior so the work-around is limited to open APs only.

2021-10-27wcn36xx: Add chained transfer support for AMSDULoic Poulain
WCNSS RX DMA transfer support is limited to 3872 bytes, which is enough for simple MPDUs (single MSDU), but not enough for cases with A-MSDU (depending on max AMSDU size or max MPDU size). In that case the MPDU is spread over multiple transfers, with the first transfer containing the MPDU header and (at least) the first A-MSDU subframe and additional transfer(s) containing the following A-MSDUs. This can be handled with a series of flags to tagging the first and last A-MSDU transfers. In that case we have to bufferize and re-linearize the A-MSDU buffers into a proper MPDU skb before forwarding to mac80211 (in the same way as it is done in ath10k). This change also includes sanity check of the buffer descriptor to prevent skb overflow.

2021-10-27wcn36xx: Enable hardware scan offload for 5Ghz bandLoic Poulain
Until now, offload scanning for 5Ghz channels was considered broken. However it was mostly a driver issue, caused by bad reporting of the beacons/probe-resp bands and frequencies, which has been fixed. We can now allow offload scan for 5GHz band, this reduces the scanning time comparing to software driven scanning. Note that offloaded scan is limited to 48 channels, check for this.

2021-10-27wcn36xx: Correct band/freq reporting on RXLoic Poulain
For packets originating from hardware scan, the channel and band is included in the buffer descriptor (bd->rf_band & bd->rx_ch). For 2Ghz band the channel value is directly reported in the 4-bit rx_ch field. For 5Ghz band, the rx_ch field contains a mapping index (given the 4-bit limitation). The reserved0 value field is also used to extend 4-bit mapping to 5-bit mapping to support more than 16 5Ghz channels. This change adds correct reporting of the frequency/band, that is used in scan mechanism. And is required for 5Ghz hardware scan support.

With commit db5ad6b7f8cd ("nvme-tcp: try to send request in queue_rq context") r2t and response PDU can get processed while send function is executing. Current data digest send code uses req->offset after kernel_sendmsg(), this creates a race condition where req->offset gets reset before it is used in send function. This can happen in two cases - 1. Target sends r2t PDU which resets req->offset. 2. Target send response PDU which completes the req and then req is used for a new command, nvme_tcp_setup_cmd_pdu() resets req->offset.

2021-10-26net/mlx5e: Add control path for SHAMPO featureBen Ben-Ishay
This commit introduces the control path infrastructure for SHAMPO feature.

SHAMPO feature is implemented as linked list striding RQ feature. To support packets splitting and payload stitching: - Enlarge the ICOSQ and the correspond CQ to support the header buffer memory regions. - Add support to create linked list striding RQ with SHAMPO feature set in the open_rq function. - Add deallocation function and corresponded calls for SHAMPO header buffer. - Add mlx5e_create_umr_klm_mkey to support KLM mkey for the header buffer. - Rename mlx5e_create_umr_mkey to mlx5e_create_umr_mtt_mkey.

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.

2021-10-26net/mlx5: Add SHAMPO caps, HW bits and enumerationsBen Ben-Ishay
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 <benishay@nvidia.com> Reviewed-by: Tariq Toukan <tariqt@nvidia.com> Signed-off-by: Saeed Mahameed <saeedm@nvidia.com>
2021-10-26net/mlx5e: Rename lro_timeout to packet_merge_timeoutBen Ben-Ishay
TIR stands for transport interface receive, the TIR object is responsible for performing all transport related operations on the receive side like packet processing, demultiplexing the packets to different RQ's, etc. lro_timeout is a field in the TIR that is used to set the timeout for lro session, this series introduces new packet merge type, therefore rename lro_timeout to packet_merge_timeout for all packet merge types.

SBSA says of the generic watchdog: All registers are 32 bits in size and should be accessed using 32-bit reads and writes. If an access size other than 32 bits is used then the results are IMPLEMENTATION DEFINED. and for qemu, the implementation will only allow 32-bit accesses resulting in a synchronous external abort when configuring the watchdog. Use lo_hi_* accessors rather than a readq/writeq.
