Pull rdma updates from Doug Ledford: "This is a big pull request. Of note is that I'm sending you the new ioctl API for the rdma subsystem. We put it up on linux-api@, but didn't get much response. The API is complex, but it solves two different problems in one go: 1) The bi-directional nature of the RDMA file write calls, which created the security hole we had to handle (and for which the fix is now causing problems for systems in production, we were a bit over zealous in the fix and the ability to open a device, then fork, then create new queue pairs on the device and use them is broken). 2) The bloat caused by different vendors implementing extensions to the base verbs API. Each vendor's hardware is slightly different, and the hardware might be suitable for one extension but not another. By the time we add generic extensions for all the different ways that the different hardware can offload things, the API becomes bloated. Things like our completion structs have started to exceed a cache line in size because of all the elements needed to support this. That in turn shows up heavily in the performance graphs with a noticable drop in performance on 100Gigabit links as our completion structs go from occupying one cache line to 1+. This API makes things like the completion structs modular in a very similar way to netlink so that your structs can only include the items needed for the offloads/features you are actually using on a given queue pair. In that way we support everything, but only use what we need, and our structs stay smaller. The ioctl API is better explained by the posting on linux-api@ than I can explain it here, so I'll just leave it at that. The rest of the pull request is typical stuff.

net/mlx4: Add user mac FW update support

2017-08-29T21:58:32Z

Adding support for updating the FW on new port mac, when port mac change is requested by the user. This info is required by the FW as OEM management tools require this info directly from the NIC FW. Check device capability bit to verify the FW supports user mac. If the FW does support it, use set_port command to notify the FW on the new mac. The feature is relevant only to PF port mac.

net/mlx4_en: Fix wrong indication of Wake-on-LAN (WoL) support

2017-08-02T17:44:09Z

Currently when WoL is supported but disabled, ethtool reports: "Supports Wake-on: d". Fix the indication of Wol support, so that the indication remains "g" all the time if the NIC supports WoL. Tested: As accepted, when NIC supports WoL- ethtool reports: Supports Wake-on: g Wake-on: d when NIC doesn't support WoL- ethtool reports: Supports Wake-on: d Wake-on: d Fixes: 14c07b1358ed ("mlx4: Wake on LAN support") Signed-off-by: Inbar Karmy Signed-off-by: Tariq Toukan Signed-off-by: David S.

(IB, net)/mlx4: Add resource utilization support

2017-07-24T14:41:35Z

Adding visibility of resource usage of QPs, CQs and counters used by virtual functions. This feature will be used to give the PF administrator more data while debugging VF status. Usage info was added to ALLOC_RES command, to notify the PF if the resource which is being reserved or allocated for the VF will be used by kernel driver or by user verbs. Updated reservation and allocation functions of QP, CQ and counter with additional usage parameter. Signed-off-by: Moshe Shemesh Signed-off-by: Leon Romanovsky Signed-off-by: Doug Ledford

{net, IB}/mlx4: Remove gfp flags argument

2017-07-18T01:21:24Z

The caller to the driver marks GFP_NOIO allocations with help of memalloc_noio-* calls now. This makes redundant to pass down to the driver gfp flags, which can be GFP_KERNEL only. The patch removes the gfp flags argument and updates all driver paths. Signed-off-by: Leon Romanovsky Signed-off-by: Leon Romanovsky Signed-off-by: Doug Ledford

net/mlx4: Fix the check in attaching steering rules

2017-06-05T03:10:05Z

Our previous patch (cited below) introduced a regression for RAW Eth QPs. Fix it by checking if the QP number provided by user-space exists, hence allowing steering rules to be added for valid QPs only.

IB/mlx4: Support RAW Ethernet when RoCE is disabled

2017-04-21T16:26:05Z

On some environments, such as certain SR-IOV VF configurations, RoCE isn't supported for mlx4 Ethernet ports. Currently the driver will not open IB device on that port. This is problematic since we do want user-space RAW Ethernet QPs functionality to remain in place. For that end, enhance the relevant driver flows such that we do create a device instance in that case. Signed-off-by: Majd Dibbiny Signed-off-by: Leon Romanovsky Signed-off-by: Doug Ledford
