Subject: [PATCH net-next V1 00/11] net/mlx5: ConnectX-4 100G Ethernet driver
Hi Dave,
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(). Thanks Alex.
This patchset introduces support in Mellanox ConnectX-4 100G Ethernet NIC.
Unlike the ConnectX-3 driver, this driver is built of a single module (there is
no mlx5_en). It is the Ethernet driver and also the low level driver for the
infiniband driver - mlx5_ib.
Many features are still missing from the driver, but all the basic
functionalities are there already.
Notes:
- Patch 3/11 ("net/mlx5_core: HW data structs/types definitions preparation
for mlx5 ehternet driver") is too big for the mail server. It is hard to split
it, since it is a generated code. I'm sending it as is, so you get it
as part of the patches. I also place it on a public git [1], to enable
reviewing it from the mailing list.
Patchset was applied on top of e60a9de ("Merge branch 'master' of
git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue")
[1] - http://git.openfabrics.org/?p=~amirv/linux.git;a=shortlog;h=refs/heads/mlx5e_v1
Thanks to Achiad, Saeed, Yevheny, Or and the whole team for making this happen,
Amir
