Most of it is typical driver and core updates, but there is the entirely new VMWare pvrdma driver. You may have noticed that there were changes in DaveM's pull request to the bnxt Ethernet driver to support a RoCE RDMA driver. The bnxt_re driver was tentatively set to be pulled in this release cycle, but it simply wasn't ready in time and was dropped (a few review comments still to address, and some multi-arch build issues like prefetch() not working across all arches). Summary: - shared mlx5 updates with net stack (will drop out on merge if Dave's tree has already been merged) - driver updates: cxgb4, hfi1, hns-roce, i40iw, mlx4, mlx5, qedr, rxe - debug cleanups - new connection rejection helpers - SRP updates - various misc fixes - new paravirt driver from vmware" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma: (210 commits) IB: Add vmw_pvrdma driver IB/mlx4: fix improper return value IB/ocrdma: fix bad initialization infiniband: nes: return value of skb_linearize should be handled MAINTAINERS: Update Intel RDMA RNIC driver maintainers MAINTAINERS: Remove Mitesh Ahuja from emulex maintainers IB/core: fix unmap_sg argument qede: fix general protection fault may occur on probe IB/mthca: Replace pci_pool_alloc by pci_pool_zalloc mlx5, calc_sq_size(): Make a debug message more informative mlx5: Remove a set-but-not-used variable mlx5: Use { } instead of { 0 } to init struct IB/srp: Make writing the add_target sysfs attr interruptible IB/srp: Make mapping failures easier to debug IB/srp: Make login failures easier to debug IB/srp: Introduce a local variable in srp_add_one() IB/srp: Fix CONFIG_DYNAMIC_DEBUG=n build IB/multicast: Check ib_find_pkey() return value IPoIB: Avoid reading an uninitialized member variable IB/mad: Fix an array index check ...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add new type of struct mlx5_frag_buf which is used to allocate fragmented buffers rather than contiguous, and make the Completion Queues (CQs) use it as they are big (default of 2MB per CQ in Striding RQ). This fixes the failures of type: "mlx5e_open_locked: mlx5e_open_channels failed, -12" due to dma_zalloc_coherent insufficient contiguous coherent memory to satisfy the driver's request when the user tries to setup more or larger rings.

Updates and Fixes: From Saeed Mahameed (2): - mlx5 IB: Skip handling unknown mlx5 events - Add ConnectX-5 PCIe 4.0 VF device ID From Artemy Kovalyov (2): - Update struct mlx5_ifc_xrqc_bits - Ensure SRQ physical address structure endianness From Eugenia Emantayev (1): - Fix length of async_event_mask New Features: From Mohamad Haj Yahia (3): mlx5 SRIOV VF max rate limit support - Introduce TSAR manipulation firmware commands - Introduce E-switch QoS management - Add SRIOV VF max rate configuration support From Mark Bloch (7): mlx5e Tc support for FWD rule with counter - Don't unlock fte while still using it - Use fte status to decide on firmware command - Refactor find_flow_rule - Group similar rules under the same fte - Add multi dest support - Add option to add fwd rule with counter - mlx5e tc support for FWD rule with counter Mark here fixed two trivial issues with the flow steering core, and did some refactoring in the flow steering API to support adding mulit destination rules to the same hardware flow table entry at once. In the last two patches added the ability to populate a flow rule with a flow counter to the same flow entry. V2: Dropped some patches that added new structures without adding any usage of them. Added SRIOV VF max rate configuration support patch that introduces the usage of the TSAR infrastructure.

| * net/mlx5: Add multi dest supportMark Bloch2016-10-301-13/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently when calling mlx5_add_flow_rule we accept only one flow destination, this commit allows to pass multiple destinations. This change forces us to change the return structure to a more flexible one. We introduce a flow handle (struct mlx5_flow_handle), it holds internally the number for rules created and holds an array where each cell points the to a flow rule. From the consumers (of mlx5_add_flow_rule) point of view this change is only cosmetic and requires only to change the type of the returned value they store. From the core point of view, we now need to use a loop when allocating and deleting rules (e.g given to us a flow handler).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | TSAR (stands for Transmit Scheduling ARbiter) is a hardware component that is responsible for selecting the next entity to serve on the transmit path. The arbitration defines the QoS policy between the agents connected to the TSAR. The TSAR is a consist two main features: 1) BW Allocation between agents: The TSAR implements a defecit weighted round robin between the agents. Each agent attached to the TSAR is assigned with a weight and it is awarded transmission tokens according to this weight. 2) Rate limer per agent: Each agent attached to the TSAR is (optionally) assigned with a rate limit. TSAR will not allow scheduling for an agent exceeding its defined rate limit. In this patch we implement the API of manipulating the TSAR.

Available only in LAG mode. - DESTROY_VPORT_LAG Ethernet flow steering returns to non-LAG behavior. Caps added: - lag_master Driver is in charge of managing the LAG. This is currently the only option. - num_lag_ports LAG is supported only if this field's value is 2. Other fields: - QP/TIS tx port affinity During LAG, this field controls on which port a QP or TIS resides. - TIS strict tx affinity When this field is set, the TIS will not be subject to port remap by CREATE_LAG/MODIFY_LAG. - LAG demux flow table Flow table used for redirecting non user-space traffic back to PF1 root flow table, if the packet was received on port two.

* | net/mlx5: Unify and improve command interfaceSaeed Mahameed2016-08-172-118/+4Star
| | | | | | | | | | | | | | | | | | | | | | | | Now as all commands use mlx5 ifc interface, instead of doing two calls for executing a command we embed command status checking into mlx5_cmd_exec to simplify the interface. Also we do here some cleanup for redundant software structures (inbox/outbox) and functions and improved command failure output.

* | {net,IB}/mlx5: Modify QP commands via mlx5 ifcSaeed Mahameed2016-08-171-17/+3Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
