2020-05-15mlx5: work around high stack usage with gccArnd Bergmann
commit 42ae1a5c76691928ed217c7e40269db27f5225e9 upstream. In some configurations, gcc tries too hard to optimize this code: drivers/net/ethernet/mellanox/mlx5/core/en_stats.c: In function 'mlx5e_grp_sw_update_stats': drivers/net/ethernet/mellanox/mlx5/core/en_stats.c:302:1: error: the frame size of 1336 bytes is larger than 1024 bytes [-Werror=frame-larger-than=] As was stated in the bug report, the reason is that gcc runs into a corner case in the register allocator that is rather hard to fix in a good way. As there is an easy way to work around it, just add a comment and the barrier that stops gcc from trying to overoptimize the function.

2019-04-23net/mlx5e: XDP, Inline small packets into the TX MPWQE in XDP xmit flowShay Agroskin
Upon high packet rate with multiple CPUs TX workloads, much of the HCA's resources are spent on prefetching TX descriptors, thus affecting transmission rates. This patch comes to mitigate this problem by moving some workload to the CPU and reducing the HW data prefetch overhead for small packets (<= 256B). When forwarding packets with XDP, a packet that is smaller than a certain size (set to ~256 bytes) would be sent inline within its WQE TX descrptor (mem-copied), when the hardware tx queue is congested beyond a pre-defined water-mark. This is added to better utilize the HW resources (which now makes one less packet data prefetch) and allow better scalability, on the account of CPU usage (which now 'memcpy's the packet into the WQE). To load balance between HW and CPU and get max packet rate, we use watermarks to detect how much the HW is congested and move the work loads back and forth between HW and CPU. Performance: Tested packet rate for UDP 64Byte multi-stream over two dual port ConnectX-5 100Gbps NICs. CPU: Intel(R) Xeon(R) CPU E5-2680 v3 @ 2.50GHz * Tested with hyper-threading disabled XDP_TX: | | before | after | | | 24 rings | 51Mpps | 116Mpps | +126% | | 1 ring | 12Mpps | 12Mpps | same | XDP_REDIRECT: ** Below is the transmit rate, not the redirection rate which might be larger, and is not affected by this patch. | | before | after | | | 32 rings | 64Mpps | 92Mpps | +43% | | 1 ring | 6.4Mpps | 6.4Mpps | same | As we can see, feature significantly improves scaling, without hurting single ring performance.

2019-04-09net/mlx5e: Rx, Fixup skb checksum for packets with tail paddingSaeed Mahameed
When an ethernet frame with ip payload is padded, the padding octets are not covered by the hardware checksum. Prior to the cited commit, skb checksum was forced to be CHECKSUM_NONE when padding is detected. After it, the kernel will try to trim the padding bytes and subtract their checksum from skb->csum. In this patch we fixup skb->csum for any ip packet with tail padding of any size, if any padding found. FCS case is just one special case of this general purpose patch, hence, it is removed.

2019-01-25net/mlx5e: Separate between ethtool and netdev software stats foldingSaeed Mahameed
mlx5e_grp_sw_update_stats can be called from two threads, 1) ndo_get_stats64 2) get_ethtool_stats For this reason and to minimize concurrency issue impact on 64bit machines mlx5e_grp_sw_update_stats folds the software stats into a temporary variable then copies it to the global driver stats, both ethtool and ndo statistics callbacks will use the global software stats variable to report whatever stats they need. Actually ndo_get_stats64 doesn't need to fold the whole software stats (mlx5e_grp_sw_update_stats), all it needs is five counters to fill the rtnl_link_stats64 relevant stats parameter. Hence this patch introduces a simpler helper function to fold software stats for ndo_get_stats64 which will work directly on rtnl_link_stats64 stats parameter and not on the global or even temporary mlx5e_sw_stats variable. Since now mlx5e_grp_sw_update_stats is not called by ndo_get_stats64 we can make it static and remove the temp var. Unlike mlx5e_grp_sw_update_stats the new fold stats function doesn't need to zero out the output statistics parameter since it is already done by the stack @dev_get_stats(). This patch is fixing stack usage of mlx5e_grp_sw_update_stats on x86 gcc-4.9 and higher, the concurrency issue between mlx5's ndo_get_stats64 and get_ethtool_stats is resolved as well.

2018-12-17net/mlx5e: Use dedicated uplink vport netdev representorOr Gerlitz
Currently, when running in sriov switchdev mode, we are using the PF netdevice as the uplink representor, this is problematic from few aspects: - will break when the PF isn't eswitch manager (e.g smart NIC env) - misalignment with other NIC switchdev drivers - makes us have and maintain special code, hurts the driver quality/robustness - which in turn opens the door for future bugs As of each and all of the above, we move to have a dedicated netdev representor for the uplink vport in a similar manner done for for the VF vports. This includes the following: 1. have an uplink rep netdev as we have for VF reps 2. all reps use same load/unload functions 3.

2018-11-19net/mlx5e: RX, verify received packet size in Linear Striding RQMoshe Shemesh
In case of striding RQ, we use MPWRQ (Multi Packet WQE RQ), which means that WQE (RX descriptor) can be used for many packets and so the WQE is much bigger than MTU. In virtualization setups where the port mtu can be larger than the vf mtu, if received packet is bigger than MTU, it won't be dropped by HW on too small receive WQE. If we use linear SKB in striding RQ, since each stride has room for mtu size payload and skb info, an oversized packet can lead to crash for crossing allocated page boundary upon the call to build_skb. So driver needs to check packet size and drop it. Introduce new SW rx counter, rx_oversize_pkts_sw_drop, which counts the number of packets dropped by the driver for being too large. As a new field is added to the RQ struct, re-open the channels whenever this field is being used in datapath (i.e., in the case of linear Striding RQ).

2018-10-10net/mlx5e: Do not ignore netdevice TX/RX queues numberFeras Daoud
The current design of mlx5e driver ignores the netdevice TX/RX queues number for netdevices that RDMA IPoIB ULP creates. Instead, the queue number is initialized to the maximum number that mlx5 thinks best for performance. As a result, ULP drivers that choose to create a netdevice with queue number that is less than the maximum channels mlx5 creates, will get a memory corruption. This fix changes the mlx5e netdev logic to respect ULP netdevices TX/RX queue number and use it when creating resources instead of the maximum channel number.

In multi-host (MH) NIC scheme, a single HW port serves multiple hosts or sockets on the same host. The HW uses a mechanism in the PCIe buffer which monitors the amount of consumed PCIe buffers per host. On a certain configuration, under congestion, the HW emulates a switch doing ECN marking on packets using ECN indication on the completion descriptor (CQE). The driver needs to set the ECN bits on the packet SKB, such that the network stack can react on that, this commit does that.

2018-03-27net/mlx5e: Recover Send Queue (SQ) from error stateEran Ben Elisha
An error TX completion (CQE) which arrived on a specific SQ indicates that this SQ got moved by the hardware to error state, which means all pending and incoming TX requests are dropped or will be dropped and no further "Good" CQEs will be generated for that SQ. Before this patch TX completions (CQEs) were not monitored and were handled as a regular CQE. This caused the SQ to stay in an error state, making it useless for xmiting new packets. Mitigation plan: In case of an error completion, schedule a recovery work which would do the following: - Mark the TXQ as DRV_XOFF to disable new packets to arrive from the stack - NAPI to flush all pending SQ WQEs (via flush_in_error_en bit) to release SW and HW resources(SKB, DMA, etc) and have the SQ and CQ consumer/producer indices synced. - Modify the SQ state ERR -> RST -> RDY (restart the SQ). - Reactivate the SQ and reset SQ cc and pc If we identify two consecutive requests for SQ recover in less than 500 msecs, drop the recover request to avoid CPU overload, as this scenario most likely happened due to a severe repeated bug.
