Amir Vadai says: ==================== net/mlx5: ConnectX-4 100G Ethernet driver This patchset extends the mlx5_core driver to support Ethernet functionality. The Ethernet functionality in the mlx5 driver is integrated into the core driver and not as separated driver. The IB functionality remains in the mlx5_ib driver as before. This functionality will enable the Ethernet capability of Mellanox's new famility of cards - ConnectX-4. Due to the fact that backword compatability is being kept, existing Connect-IB cards that are using this driver are fully working with the modified driver, and no issues with current deployments should be seen. Like the ConnectX-3 cards, ConnectX-4 is a VPI (Virtual Port Interface - every port can be configured as Infiniband or Ethernet) card. Unlike previous generations, the ConnectX-4 has a separate PCI function per port. The current code has a limitation that Infiniband and Ethernet port types are mutually exclusive. When the driver is compiled with Ethernet support, the Infiniband functionality is disabled and vice versa. To control that we added the CONFIG_MLX5_CORE_EN config directive which is 'n' by default, but can be changed by the user. This limitation is short-lived and would be addressed soon. As part of this patchset, mlx5_ifc.h was heavily modified [1]. This file is now generated automatically from the device specification document. Since this patch is too big for the mail server, it might be missing in the mailing list, but could be pulled from an external git repository [2]. irq name selection is done at driver initialization and doesn't contain the interface name as part of the irq name. irq_balancer will still work thanks to an improvement introduced by Neil Horman [3] to use sysfs instead of /proc/interrupts. Patchset was applied on top of commit ed2dfd90 ("tcp/dccp: warn user for preferred ip_local_port_range") [1] - Patch 4/11 ("net/mlx5_core: HW data structs/types definitions preparation for mlx5 ehternet driver") [2] - http://git.openfabrics.org/?p=~amirv/linux.git;a=shortlog;h=refs/heads/mlx5e_v1 [3] - kernel: da8d1c8b PCI/sysfs: add per pci device msi[x] irq listing (v5) irq_balancer: 32a7757 Complete rework of how we detect and classify irqs Thanks to Achiad, Saeed, Yevheny, Or and the whole team for making this happen, Amir Changes from V4: - Removed Patch 3/12: net/mlx5_core: Add EQ renaming mechanism - Patch 12/12: net/mlx5: Extend mlx5_core to support ConnectX-4 Ethernet functionality - irq name is created on driver initialization, therefore it won't contain the network interface name in it. This won't effect irq_balancer thanks to patches introduced by Neil Horman to use sysfs instead of /proc/interrupts. Changes from V3: - PATCH 8/11: net/mlx5_core: Set/Query port MTU commands - Return value directly - no need for err. Changes from V2: - Improved changelogs and cover-letter - Added CONFIG_MLX5_EN to disable/enable the Ethernet functionality - Moved en.h and wq.[ch] into the patch with data-path related code Changes from V1: - Added patch 1/12 ("net/mlx5_core,mlx5_ib: Do not use vmap() on coherent memory") Changes from V0: - Removed V0 Patch 1/11 ("net/mlx5_core: Virtually extend work/completion queue buffers by one page") due to misuse of DMA API. Thanks Dave. - Patch 1/11 ("net/mlx5_core: Set irq affinity hints"): - Use kcalloc instead of kzalloc - Fix build error when CONFIG_CPUMASK_OFFSTACK=n. Driver loading will fail now if cpumask allocation is failing. - Using dev_to_node helper. Thanks, Ido. - Patch 3/11 ("net/mlx5_core: HW data structs/types definitions preparation for mlx5 ehternet driver") - Removed Mellanox internal comment at the head of the file. Thanks Joe - Patch 6/11 ("net/mlx5_core: Implement get/set port status") - Use direct return of function's result. Thanks Sergei. - Added Patch 8/11 ("net/mlx5_core: Set/Query port MTU commands") - Patch 9/11 ("net/mlx5: Ethernet Datapath files") - Use rq->wqe_sz instead of skb_end_offset. Thanks Ido. - Use dma_wmb() when possible instead of wmb(). Thanks Alex. - Fix checkpatch issues - Patch 10/11 ("net/mlx5: ethernet resources handling") - checkpatch issues - Added missing include - Patch 11/11 ("net/mlx5: Ethernet driver") - checkpatch issues - fixed typo - Modified use of affinity hint - Using dev_to_node helper. Thanks, Ido. - Use new hardware commands from Patch 8/11 ("net/mlx5_core: Set/Query port MTU commands") to get/set port MTU in hardware. - Removed NETIF_F_SG since hardware ring wraparound is not supported - Use dma_wmb() when possible instead of wmb().
