This patch is preparing the netdev part at the IPoIB driver to be able to use the ipoib_options. It deals with the two flows from the .ndo: ipoib_open and ipoib_stop. The code is rearranged as follows: * All operations which deal with the hardware resources, (for example change QP state, post-receive etc.) are performed in one place. * All operations that are control oriented (like restart multicast task, start the reap_ah etc.) are performed in separate place. The functions that deal with the hardware resources now located at __ipoib_ib_dev_open for the ipoib_open flow and __ipoib_ib_dev_stop for ipoib_stop.

This patch prepares init and teardown flows so we can call them through ipoib_options function pointers. It arranges that area of code as the following: * All operations which deal with the resource allocation/deletion are performed in one place. * All operations that are control oriented, meaning that they are not connected to a specific hardware, are performed in a separate place. The operations for allocation of hardware resources are now in the function ipoib_dev_init_default, and the deletion of all the resources are in ipoib_dev_uninit_default The only exception is the creation of the PD object, which is used both for resource allocation (create QP etc.) and for control flows like creating AH. It also does: * Move creation of rx_ring and tx_ring to be in the resources allocation area. * Move the function ipoib_ib_dev_open that does the open device to the control area instead of the dev_init which creates resources.

Add RDMA netdev interface to ib device structure allowing RDMA netdev devices to be allocated by ib clients. The idea is to allow to providers to optimize IPoIB data path. New struct that includes functions and data member is exposed. It exposes set of callback functions for handling data path flows in IPoIB driver. Each provider can support these set of functions in order to optimize its specific data path, and let IPoIB to leverage its data path. There is an assumption, that providers should give the full set of functions and not only part of them, in order to work properly.

Saeed Mahameed says: ==================== Mellanox, mlx5 RDMA net device support This series provides the lower level mlx5 support of RDMA netdevice creation API [1] suggested and introduced by Intel's HFI OPA VNIC netdevice driver [2], to enable IPoIB mlx5 RDMA netdevice creation. mlx5 IPoIB RDMA netdev will serve as an acceleration netdevice for the current IPoIB ULP generic netdevice, providing: - mlx5 RSS support. - mlx5 HW RX,TX offloads (checksum, TSO, LRO, etc ..). - Full mlx5 HW features transparent to the ULP itself. The idea here is to reuse and benefit from the already implemented mlx5e netdevice management and channels API for both etherent and RDMA netdevices, since both IPoIB and Ethernet netdevices share same common mlx5 HW resources (with some small exceptions) and share most of the control/data path logic, it is more natural to have them share the same code. The differences between IPoIB and Ethernet netdevices can be summarized to: Steering: In mlx5, IPoIB traffic is sent and received from an underlay special QP, and in Ethernet the traffic is handled by vports and vport steering is managed by e-switch or FW. For IPoIB traffic to get steered correctly the only thing we need to do is to create RSS HW contexts for RX and TX HW contexts for TX (similar to mlx5e) with the underlay QP attached to them (underlay QP will be 0 in case of Ethernet). RX,TX: Since IPoIB traffic is different, slightly modified RX and TX handlers are required, still we do some code reuse in data path via common helper functions. All of the other generic netdevice and mlx5 aspects will be shared between mlx5 Ethernet and IPoIB netdevices, e.g. - Channels creation and handling (RQs,SQs,CQs, NAPI, interrupt moderation, etc..) - Offloads, checksum, GRO, LRO, TSO, and more. - netdevice logic and non Ethernet specific ndos (open/close, etc..) In order to achieve what we want: In patchet 1 to 3, Erez added the supported for underlay QP in mlx5_ifc and refactored the mlx5 steering code to accept the underlay QP as a parameter for creating steering objects and enabled flow steering for IB link. Then we are going to use the mlx5e netdevice profile, which is already used to separate between NIC and VF representors netdevices, to create new type of IPoIB netdevice profile. For that, one small refactoring is required to make mlx5e netdevice profile management more genetic and agnostic to link type which is done in patch #4. In patch #5, we introduce ipoib.c to host all of mlx5 IPoIB (mlx5i) specific logic and a skeleton for the IPoIB mlx5 netdevice profile, and we will start filling it in next patches, using mlx5e already existing APIs. Patch #6 and #7, Implement init/cleanup RX mlx5i netdev profile handlers to create mlx5 RSS resources, same as mlx5e but without vlan and L2 steering tables. Patch #8, Implement init/cleanup TX mlx5i netdev profile handlers, to create TX resources same as mlx5e but with one TC (tc = 0) support. Patch #9, Implement mlx5i open/close ndos, where we reuese the mlx5e channels API, to start/stop TX/RX channels. Patch #10, Create the underlay QP and attach it to mlx5i RSS and TX HW contexts. Patch #11 and #12, Break down the mlx5e xmit flow into smaller helper function and implement the mlx5i IPoIB xmit routine. Patch #13 and #14, Have an RX handler per netdevice profile. We already do this before this series in a non clean way to separate between NIC netdev and VF representor RX handlers, in patch 13 we make the RX handler generic and bound to a profile and in patch 14 we implement the IPoIB RX handlers. Patch #15, Small cleanup to avoid e-switch with IPoIB netdev. In order to enable mlx5 IPoIB, a merge between the IPoIB RDMA netdev offolad support [3] - which was alread submitted to the rdma mailing list - and this series is required plus an extra small patch [4] which will connect between both sides and actually enables the offload. Once both patch-sets are merged into linux we will have to submit the extra small patch [4], to enable the feature. Thanks, Saeed.
