2021-12-31net: hns3: refactor hclge_cmd_send with new hclge_comm_cmd_send APIJie Wang8-373/+100
This patch firstly uses new hardware description struct hclge_comm_hw as child member of hclge_hw and deletes the original child memebers of hclge_hw. All the hclge_hw variables used in PF module is modified according to the new hclge_hw. Secondly hclge_cmd_send is refactored to use hclge_comm_cmd_send APIs. The old functions called by hclge_cmd_send are deleted and hclge_cmd_send is kept to avoid too many meaningless modifications.

This patch create new set of unified hclge_comm_cmd_send APIs for PF and VF cmdq module. Subfunctions called by hclge_comm_cmd_send are also created include cmdq result check, cmdq return code conversion and ring space opertaion APIs. These new common cmdq APIs will be used to replace the old PF and VF cmdq APIs in next patches.

2021-12-31net: hns3: create new cmdq hardware description structure hclge_comm_hwJie Wang3-8/+57
Currently PF and VF cmdq APIs use struct hclge(vf)_hw to describe cmdq hardware information needed by hclge(vf)_cmd_send. There are a little differences between its child struct hclge_cmq_ring and hclgevf_cmq_ring. It is redundent to use two sets of structures to support same functions. So this patch creates new set of common cmdq hardware description structures(hclge_comm_hw) to unify PF and VF cmdq functions. The struct hclge_desc is still kept to avoid too many meaningless replacement. These new structures will be used to unify hclge(vf)_hw structures in PF and VF cmdq APIs in next patches.

2021-12-31net: hns3: refactor hns3 makefile to support hns3_common moduleJie Wang3-25/+11
Currently we plan to refactor PF and VF cmdq module. A new file folder hns3_common will be created to store new common APIs used by PF and VF cmdq module. Thus the PF and VF compilation process will both depends on the hns3_common. This may cause parallel building problems if we add a new makefile building unit. So this patch combined the PF and VF makefile scripts to the top level makefile to support the new hns3_common which will be created in the next patch.

2021-12-31net/mlx5: Set SMFS as a default steering mode if device supports itYevgeny Kliteynik1-0/+5
Set SMFS (SW-managed flow steering) as a default steering mode instead of DMFS (device-managed flow steering) In SMFS, the driver writes the STEs (Steering Table Entries) directly to the device's ICM, which allows for a higher rule insertion rate than through using FW command interface, as it is done in DMFS. SMFS/DMFS steering modes can be configured through devlink param 'flow_steering_mode'. The possible values are 'smfs' or 'dmfs'. The desired 'flow_steering_mode' param value should be set before enabling switchdev mode. Example: # devlink dev param set pci/0000:05:00.0 name flow_steering_mode smfs # devlink dev eswitch set pci/0000:05:00.0 mode switchdev Signed-off-by: Yevgeny Kliteynik <kliteyn@nvidia.com>
2021-12-31net/mlx5: DR, Ignore modify TTL if device doesn't support itYevgeny Kliteynik1-3/+18
When modifying TTL, packet's csum has to be recalculated. Due to HW issue in ConnectX-5, csum recalculation for modify TTL is supported through a work-around that is specifically enabled by configuration. If the work-around isn't enabled, ignore the modify TTL action rather than adding an unsupported action. Signed-off-by: Yevgeny Kliteynik <kliteyn@nvidia.com>
2021-12-31net/mlx5: DR, Improve steering for empty or RX/TX-only matchersYevgeny Kliteynik4-130/+156
Every matcher has RX and TX paths. When a new matcher is created, its RX and TX start/end anchors are connected to the respective RX and TX anchors of the previous and next matchers. This creates a potential performance issue: when a certain rule is added to a matcher, in many cases it is RX or TX only rule, which may create a long chain of RX/TX-only paths w/o the actual rules. This patch aims to handle this issue. RX and TX matchers are now handled separately: matcher connection in the matchers chain is split into two separate lists: RX only and TX only. when a new matcher is created, it is initially created 'detached' - its RX/TX members are not inserted into the table's matcher list. When an actual rule is added, only its appropriate RX or TX nic matchers are then added to the table's nic matchers list and inserted into its place in the chain of matchers. I.e., if the rule that is being added is an RX-only rule, only the RX part of the matcher will be connected to the chain, while TX part of the matcher remains detached and doesn't prolong the TX chain of the matchers. Same goes for rule deletion: when the last RX/TX rule of the nic matcher is destroyed, the nic matcher is removed from its list. Signed-off-by: Yevgeny Kliteynik <kliteyn@nvidia.com>

queue Tony Nguyen says: ==================== 1GbE Intel Wired LAN Driver Updates 2021-12-29 Ruud Bos says: The igb driver provides support for PEROUT and EXTTS pin functions that allow adapter external use of timing signals. At Hottinger Bruel & Kjaer we are using the PEROUT function to feed a PTP corrected 1pps signal into an FPGA as cross system synchronized time source. Support for the PEROUT and EXTTS SDP functions is currently limited to i210/i211 based adapters. This patch series enables these functions also for 82580/i354/i350 based ones. Because the time registers of these adapters do not have the nice split in second rollovers as the i210 has, the implementation is slightly more complex compared to the i210 implementation. The PEROUT function has been successfully tested on an i350 based ethernet adapter. Using the following user space code excerpt, the driver outputs a PTP corrected 1pps signal on the SDP0 pin of an i350: struct ptp_pin_desc desc; memset(&desc, 0, sizeof(desc)); desc.index = 0; desc.func = PTP_PF_PEROUT; desc.chan = 0; if (ioctl(fd, PTP_PIN_SETFUNC, &desc) == 0) { struct timespec ts; if (clock_gettime(clkid, &ts) == 0) { struct ptp_perout_request rq; memset(&rq, 0, sizeof(rq)); rq.index = 0; rq.start.sec = ts.tv_sec + 1; rq.start.nsec = 500000000; rq.period.sec = 1; rq.period.nsec = 0; if (ioctl(fd, PTP_PEROUT_REQUEST, &rq) == 0) { /* 1pps signal is now available on SDP0 */ } } } The added EXTTS function has not been tested. However, looking at the data sheets, the layout of the registers involved match the i210 exactly except for the time registers mentioned before. Hence the almost identical implementation. --- Note: I made changes to fix RCT and checkpatch messages regarding unnecessary parenthesis. ==================== Acked-by: Richard Cochran <richardcochran@gmail.com> Signed-off-by: David S.

2021-12-29net: Don't include filter.h from net/sock.hJakub Kicinski22-0/+26
sock.h is pretty heavily used (5k objects rebuilt on x86 after it's touched). We can drop the include of filter.h from it and add a forward declaration of struct sk_filter instead. This decreases the number of rebuilt objects when bpf.h is touched from ~5k to ~1k. There's a lot of missing includes this was masking. Primarily in networking tho, this time.

2021-12-28net/mlx5e: Fix wrong features assignment in case of errorGal Pressman1-6/+5
In case of an error in mlx5e_set_features(), 'netdev->features' must be updated with the correct state of the device to indicate which features were updated successfully. To do that we maintain a copy of 'netdev->features' and update it after successful feature changes, so we can assign it to back to 'netdev->features' if needed. However, since not all netdev features are handled by the driver (e.g. GRO/TSO/etc), some features may not be updated correctly in case of an error updating another feature. For example, while requesting to disable TSO (feature which is not handled by the driver) and enable HW-GRO, if an error occurs during HW-GRO enable, 'oper_features' will be assigned with 'netdev->features' and HW-GRO turned off. TSO will remain enabled in such case, which is a bug. To solve that, instead of using 'netdev->features' as the baseline of 'oper_features' and changing it on set feature success, use 'features' instead and update it in case of errors.

Fix a memory leak with decap rule with internal port as destination device.

Tony Nguyen says: ==================== 10GbE Intel Wired LAN Driver Updates 2021-12-28 Alexander Lobakin says: napi_build_skb() I introduced earlier this year ([0]) aims to decrease MM pressure and the overhead from in-place kmem_cache_alloc() on each Rx entry processing by decaching skbuff_heads from NAPI per-cpu cache filled prior to that by napi_consume_skb() (so it is sort of a direct shortcut for free -> mm -> alloc cycle). Currently, no in-tree drivers use it. Switch all Intel Ethernet drivers to it to get slight-to-medium perf boosts depending on the frame size. ice driver, 50 Gbps link, pktgen + XDP_PASS (local in) sample: frame_size/nthreads 64/42 128/20 256/8 512/4 1024/2 1532/1 net-next (Kpps) 46062 34654 18248 9830 5343 2714 series 47438 34708 18330 9875 5435 2777 increase 2.9% 0.15% 0.45% 0.46% 1.72% 2.32% Additionally, e1000's been switched to napi_consume_skb() as it's safe and works fine there, and there's no point in napi_build_skb() without paired NAPI cache feeding point.
