* net/mlx5e: Use workqueue for vxlan opsMatthew Finlay2016-05-033-16/+49
| | | | | | | | | | | | The vxlan add/delete port NDOs are called under rcu lock. The current mlx5e implementation can potentially block in these calls, which is not allowed. Move to using the mlx5e workqueue to handle these NDOs.

* net/mlx5e: Implement a mlx5e workqueueMatthew Finlay2016-05-032-11/+20
| | | | | | | | | | | Implement a mlx5e workqueue to handle all mlx5e specific tasks. Move all tasks currently using the system workqueue to the new workqueue. This is in preparation for vxlan using the mlx5e workqueue in order to schedule port add/remove operations.

* net/mlx5: Kconfig: Fix MLX5_EN/VXLAN build issueMatthew Finlay2016-05-031-0/+1
| | | | | | | | | | | | | When MLX5_EN=y MLX5_CORE=y and VXLAN=m there is a linker error for vxlan_get_rx_port() due to the fact that VXLAN is a module. Change Kconfig to select VXLAN when MLX5_CORE=y. When MLX5_CORE=m there is no dependency on the value of VXLAN.

* net/mlx5: Unmap only the relevant IO memory mappingGal Pressman2016-05-031-2/+4
| | | | | | | | | | | | When freeing UAR the driver tries to unmap uar->map and uar->bf_map which are mutually exclusive thus always unmapping a NULL pointer. Make sure we only call iounmap() once, for the actual mapping.

* net/mlx5: Add pci shutdown callbackMajd Dibbiny2016-04-242-6/+32
| | | | | | | | | | | | | | | | | This patch introduces kexec support for mlx5. When switching kernels, kexec() calls shutdown, which unloads the driver and cleans its resources. In addition, remove unregister netdev from shutdown flow. This will allow a clean shutdown, even if some netdev clients did not release their reference from this netdev. Releasing The HW resources only is enough as the kernel is shutting down Signed-off-by: Majd Dibbiny <majd@mellanox.com> Signed-off-by: Tariq Toukan <tariqt@mellanox.com> Signed-off-by: Haggai Abramovsky <hagaya@mellanox.com> Signed-off-by: Saeed Mahameed <saeedm@mellanox.com> Signed-off-by: David S.

* net/mlx5e: Use vport MTU rather than physical port MTUSaeed Mahameed2016-04-242-9/+75
| | | | | | | | | | | | | | | | | Set and report vport MTU rather than physical MTU, Driver will set both vport and physical port mtu and will rely on the query of vport mtu. SRIOV VFs have to report their MTU to their vport manager (PF), and this will allow them to work with any MTU they need without failing the request. Also for some cases where the PF is not a port owner, PF can work with MTU less than the physical port mtu if set physical port mtu didn't take effect.

This fixes the case where a user wants to set invalid MTU, the driver will fail to satisfy this request and the interface will stay down.

This is a monster pull request. I held off on the hfi1 driver updates (the hfi1 driver is intimately tied to the qib driver and the new rdmavt software library that was created to help both of them) in my first pull request. The hfi1/qib/rdmavt update is probably 90% of this pull request. The hfi1 driver is being left in staging so that it can be fixed up in regards to the API that Al and yourself didn't like. Intel has agreed to do the work, but in the meantime, this clears out 300+ patches in the backlog queue and brings my tree and their tree closer to sync. This also includes about 10 patches to the core and a few to mlx5 to create an infrastructure for configuring SRIOV ports on IB devices. That series includes one patch to the net core that we sent to netdev@ and Dave Miller with each of the three revisions to the series. We didn't get any response to the patch, so we took that as implicit approval. Finally, this series includes Intel's new iWARP driver for their x722 cards. It's not nearly the beast as the hfi1 driver. It also has a linux-next merge issue, but that has been resolved and it now passes just fine. Summary: - A few minor core fixups needed for the next patch series - The IB SRIOV series. This has bounced around for several versions. Of note is the fact that the first patch in this series effects the net core. It was directed to netdev and DaveM for each iteration of the series (three versions total). Dave did not object, but did not respond either. I've taken this as permission to move forward with the series. - The new Intel X722 iWARP driver - A huge set of updates to the Intel hfi1 driver. Of particular interest here is that we have left the driver in staging since it still has an API that people object to. Intel is working on a fix, but getting these patches in now helps keep me sane as the upstream and Intel's trees were over 300 patches apart" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma: (362 commits) IB/ipoib: Allow mcast packets from other VFs IB/mlx5: Implement callbacks for manipulating VFs net/mlx5_core: Implement modify HCA vport command net/mlx5_core: Add VF param when querying vport counter IB/ipoib: Add ndo operations for configuring VFs IB/core: Add interfaces to control VF attributes IB/core: Support accessing SA in virtualized environment IB/core: Add subnet prefix to port info IB/mlx5: Fix decision on using MAD_IFC net/core: Add support for configuring VF GUIDs IB/{core, ulp} Support above 32 possible device capability flags IB/core: Replace setting the zero values in ib_uverbs_ex_query_device net/mlx5_core: Introduce offload arithmetic hardware capabilities net/mlx5_core: Refactor device capability function net/mlx5_core: Fix caching ATOMIC endian mode capability ib_srpt: fix a WARN_ON() message i40iw: Replace the obsolete crypto hash interface with shash IB/hfi1: Add SDMA cache eviction algorithm IB/hfi1: Switch to using the pin query function IB/hfi1: Specify mm when releasing pages ...

Also update current users of the API. PFs may call mlx5_core_query_vport_counter with other_vport set to indicate that they are querying a virtual function. The virtual function to be queried is given by the vf parameter. Virtual function numbering is zero based so the first VF is 0 and so on. When a PF queries its own function, the other_vport parameter is cleared.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We only need to flush the irq handler to make sure it does not queue a work into the global work queue after we start to flush it. So using synchronize_irq() is more appropriate than a spin lock. Signed-off-by: Tariq Toukan <tariqt@mellanox.com> Signed-off-by: Saeed Mahameed <saeedm@mellanox.com> Signed-off-by: David S.

For that we now create MAX_NUM_TC num of TISs (one per prio) on netdevice creation instead of priv->params.num_tc which was always 1. So far each channel had a single TXQ, Now each channel has a TXQ per TC (Traffic Class). Added en_dcbnl.c which implements the set/get DCBNL IEEE ETS, set/get dcbx and registers the mlx5e dcbnl ops. We still use the kernel's default TXQ selection method to select the channel to transmit through but now we use our own method to select the TXQ inside the channel based on VLAN priority. In mlx5, as opposed to mlx4, tc group N gets lower priority than tc group N+1.

The current code base uses MR (memory region) naming, which is inaccurate. Changing MR to mkey in order to represent its different usages more accurately.
