2020-08-05RDMA/mlx5: Fix flow destination setting for RDMA TX flow tableMichael Guralnik
For RDMA TX flow table, set destination type to be 'port' and prevent creation of flows with TIR destination. As RDMA TX is an egress flow table the rules on this flow table should not forward traffic back to the NIC and should set the destination to be the port. Without the setting of this destination type flow rules on the RDMA TX flow tables are not created as FW invokes a syndrome for undefined destination for the rule.

- Use pci_host_bridge.windows list directly instead of splicing in a temporary list for cadence, mvebu, host-common (Rob Herring) - Use pci_host_probe() instead of open-coding all the pieces for altera, brcmstb, iproc, mobiveil, rcar, rockchip, tegra, v3, versatile, xgene, xilinx, xilinx-nwl (Rob Herring) - Convert to devm_platform_ioremap_resource_byname() instead of open-coding platform_get_resource_byname() and devm_ioremap_resource() for altera, cadence, mediatek, rockchip, tegra, xgene (Dejin Zheng) - Convert to devm_platform_ioremap_resource() instead of open-coding platform_get_resource() and devm_ioremap_resource() for aardvark, brcmstb, exynos, ftpci100, versatile (Dejin Zheng) - Remove redundant error messages from devm_pci_remap_cfg_resource() callers (Dejin Zheng) - Drop useless PCI_ENABLE_PROC_DOMAINS from versatile driver (Rob Herring) - Default host bridge parent device to the platform device (Rob Herring) - Drop unnecessary zeroing of host bridge fields (Rob Herring) - Use pci_is_root_bus() instead of tracking root bus number separately in aardvark, designware (imx6, keystone, designware-host), mobiveil, xilinx-nwl, xilinx, rockchip, rcar (Rob Herring) - Set host bridge bus number in pci_scan_root_bus_bridge() instead of each driver for aardvark, designware-host, host-common, mediatek, rcar, tegra, v3-semi (Rob Herring) - Use bridge resources instead of parsing DT 'ranges' again for cadence (Rob Herring) - Remove private bus number and range from cadence (Rob Herring) - Use devm_pci_alloc_host_bridge() to simplify rcar (Rob Herring) - Use struct pci_host_bridge.windows list directly rather than a temporary (Rob Herring) - Reduce OF "missing non-prefetchable window" from error to warning message (Rob Herring) - Convert rcar-gen2 from old Arm-specific pci_common_init_dev() to new arch-independent interfaces (Rob Herring) - Move DT resource setup into devm_pci_alloc_host_bridge() (Rob Herring) - Set bridge map_irq and swizzle_irq to default functions; drivers that don't support legacy IRQs (iproc) need to undo this (Rob Herring) * pci/host-probe-refactor: PCI: Set bridge map_irq and swizzle_irq to default functions PCI: Move DT resource setup into devm_pci_alloc_host_bridge() PCI: rcar-gen2: Convert to use modern host bridge probe functions PCI: of: Reduce missing non-prefetchable memory region to a warning PCI: rcar: Use struct pci_host_bridge.windows list directly PCI: rcar: Use devm_pci_alloc_host_bridge() PCI: cadence: Remove private bus number and range storage PCI: cadence: Use bridge resources for outbound window setup PCI: Move setting pci_host_bridge.busnr out of host drivers PCI: rcar: Use pci_is_root_bus() to check if bus is root bus PCI: rockchip: Use pci_is_root_bus() to check if bus is root bus PCI: xilinx: Use pci_is_root_bus() to check if bus is root bus PCI: xilinx-nwl: Use pci_is_root_bus() to check if bus is root bus PCI: mobiveil: Use pci_is_root_bus() to check if bus is root bus PCI: designware: Use pci_is_root_bus() to check if bus is root bus PCI: aardvark: Use pci_is_root_bus() to check if bus is root bus PCI: Drop unnecessary zeroing of bridge fields PCI: Set default bridge parent device PCI: versatile: Drop flag PCI_ENABLE_PROC_DOMAINS PCI: controller: Remove duplicate error message PCI: controller: Convert to devm_platform_ioremap_resource() PCI: controller: Convert to devm_platform_ioremap_resource_byname() PCI: xilinx: Use pci_host_probe() to register host PCI: xilinx-nwl: Use pci_host_probe() to register host PCI: rockchip: Use pci_host_probe() to register host PCI: rcar: Use pci_host_probe() to register host PCI: iproc: Use pci_host_probe() to register host PCI: altera: Use pci_host_probe() to register host PCI: xgene: Use pci_host_probe() to register host PCI: versatile: Use pci_host_probe() to register host PCI: v3: Use pci_host_probe() to register host PCI: tegra: Use pci_host_probe() to register host PCI: mobiveil: Use pci_host_probe() to register host PCI: brcmstb: Use pci_host_probe() to register host PCI: host-common: Use struct pci_host_bridge.windows list directly PCI: mvebu: Use struct pci_host_bridge.windows list directly PCI: cadence: Use struct pci_host_bridge.windows list directly # Conflicts: # drivers/pci/controller/cadence/pcie-cadence-host.c
