git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma Pull rmda fixes from Doug Ledford. "First round of -rc fixes. Due to various issues, I've been away and couldn't send a pull request for about three weeks. There were a number of -rc patches that built up in the meantime (some where there already from the early -rc stages). Obviously, there were way too many to send now, so I tried to pare the list down to the more important patches for the -rc cycle. Most of the code has had plenty of soak time at the various vendor's testing setups, so I doubt there will be another -rc pull request this cycle. I also tried to limit the patches to those with smaller footprints, so even though a shortlog is longer than I would like, the actual diffstat is mostly very small with the exception of just three files that had more changes, and a couple files with pure removals.

2016-11-16IB/mlx5: Resolve soft lock on massive reg MRsMoshe Lazer2-1/+7
When calling reg_mr of large MRs (e.g. 4GB) from multiple processes and MR caches can't supply the required amount of MRs the slow-path of MR allocation may be used. In this case we need to serialize the slow-path between the processes to avoid soft lock.

2016-11-16IB/mlx5: Use cache line size to select CQE strideDaniel Jurgens1-2/+1
When creating kernel CQs use 128B CQE stride if the cache line size is 128B, 64B otherwise. This prevents multiple CQEs from residing in a 128B cache line, which can cause retries when there are concurrent read and writes in one cache line. Tested with IPoIB on PPC64, saw ~5% throughput improvement.

This patch decouples and moves vendors specific structures to common UAPI folder which will be visible to all consumers. These structures are used by user-space library driver (libmlx5) and currently manually copied to that library.

This is done in two steps: 1) Issuing CREATE_VPORT_LAG in order to have Ethernet traffic from both ports arriving on PF0 root flowtable, so we will be able to catch all raw-eth traffic on PF0. 2) Creation of LAG demux flowtable in order to direct all non-raw-eth traffic back to its source port, assuring that normal Ethernet traffic "jumps" to the root flowtable of its RX port (non-LAG behavior).

2016-10-07IB/mlx5: Port events in RoCE now rely on netdev eventsAviv Heller1-15/+51

2016-08-17{net,IB}/mlx5: Modify QP commands via mlx5 ifcSaeed Mahameed1-16/+6
Prior to this patch we assumed that modify QP commands have the same layout. In ConnectX-4 for each QP transition there is a specific command and their layout can vary. e.g: 2err/2rst commands don't have QP context in their layout and before this patch we posted the QP context in those commands. Fortunately the FW only checks the suffix of the commands and executes them, while ignoring all invalid data sent after the valid command layout. This patch removes mlx5_modify_qp_mbox_in and changes mlx5_core_qp_modify to receive the required transition and QP context with opt_param_mask if needed. This way the caller is not required to provide the command inbox layout and it will be generated automatically. mlx5_core_qp_modify will generate the command inbox/outbox layouts according to the requested transition and will fill the requested parameters.
