git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma Pull inifiniband/rdma updates from Doug Ledford: "This is a fairly sizeable set of changes. I've put them through a decent amount of testing prior to sending the pull request due to that. There are still a few fixups that I know are coming, but I wanted to go ahead and get the big, sizable chunk into your hands sooner rather than waiting for those last few fixups. Of note is the fact that this creates what is intended to be a temporary area in the drivers/staging tree specifically for some cleanups and additions that are coming for the RDMA stack. We deprecated two drivers (ipath and amso1100) and are waiting to hear back if we can deprecate another one (ehca). We also put Intel's new hfi1 driver into this area because it needs to be refactored and a transfer library created out of the factored out code, and then it and the qib driver and the soft-roce driver should all be modified to use that library. I expect drivers/staging/rdma to be around for three or four kernel releases and then to go away as all of the work is completed and final deletions of deprecated drivers are done. Summary of changes for 4.3: - Create drivers/staging/rdma - Move amso1100 driver to staging/rdma and schedule for deletion - Move ipath driver to staging/rdma and schedule for deletion - Add hfi1 driver to staging/rdma and set TODO for move to regular tree - Initial support for namespaces to be used on RDMA devices - Add RoCE GID table handling to the RDMA core caching code - Infrastructure to support handling of devices with differing read and write scatter gather capabilities - Various iSER updates - Kill off unsafe usage of global mr registrations - Update SRP driver - Misc mlx4 driver updates - Support for the mr_alloc verb - Support for a netlink interface between kernel and user space cache daemon to speed path record queries and route resolution - Ininitial support for safe hot removal of verbs devices" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma: (136 commits) IB/ipoib: Suppress warning for send only join failures IB/ipoib: Clean up send-only multicast joins IB/srp: Fix possible protection fault IB/core: Move SM class defines from ib_mad.h to ib_smi.h IB/core: Remove unnecessary defines from ib_mad.h IB/hfi1: Add PSM2 user space header to header_install IB/hfi1: Add CSRs for CONFIG_SDMA_VERBOSITY mlx5: Fix incorrect wc pkey_index assignment for GSI messages IB/mlx5: avoid destroying a NULL mr in reg_user_mr error flow IB/uverbs: reject invalid or unknown opcodes IB/cxgb4: Fix if statement in pick_local_ip6adddrs IB/sa: Fix rdma netlink message flags IB/ucma: HW Device hot-removal support IB/mlx4_ib: Disassociate support IB/uverbs: Enable device removal when there are active user space applications IB/uverbs: Explicitly pass ib_dev to uverbs commands IB/uverbs: Fix race between ib_uverbs_open and remove_one IB/uverbs: Fix reference counting usage of event files IB/core: Make ib_dealloc_pd return void IB/srp: Create an insecure all physical rkey only if needed ...

2015-09-03MIPS: Remove all the uses of custom gpio.hAlban Bedel1-0/+2
Currently CONFIG_ARCH_HAVE_CUSTOM_GPIO_H is defined for all MIPS machines, and each machine type provides its own gpio.h. However only a handful really implement the GPIO API, most just forward everythings to gpiolib. The Alchemy machine is notable as it provides a system to allow implementing the GPIO API at the board level. But it is not used by any board currently supported, so it can also be removed. For most machine types we can just remove the custom gpio.h, as well as the custom wrappers if some exists. Some of the code found in the wrappers must be moved to the respective GPIO driver. A few more fixes are need in some drivers as they rely on linux/gpio.h to provides some machine specific definitions, or used asm/gpio.h instead of linux/gpio.h for the gpio API.

2015-09-02net: fec: clear receive interrupts before processing a packetRussell King1-0/+1
The patch just to re-submit the patch "db3421c114cfa6326" because the patch "4d494cdc92b3b9a0" remove the change. Clear any pending receive interrupt before we process a pending packet. This helps to avoid any spurious interrupts being raised after we have fully cleaned the receive ring, while still allowing an interrupt to be raised if we receive another packet. The position of this is critical: we must do this prior to reading the next packet status to avoid potentially dropping an interrupt when a packet is still pending.

2015-09-02xen-netback: add support for multicast controlPaul Durrant4-0/+137
Xen's PV network protocol includes messages to add/remove ethernet multicast addresses to/from a filter list in the backend. This allows the frontend to request the backend only forward multicast packets which are of interest thus preventing unnecessary noise on the shared ring. The canonical netif header in git://xenbits.xen.org/xen.git specifies the message format (two more XEN_NETIF_EXTRA_TYPEs) so the minimal necessary changes have been pulled into include/xen/interface/io/netif.h. To prevent the frontend from extending the multicast filter list arbitrarily a limit (XEN_NETBK_MCAST_MAX) has been set to 64 entries. This limit is not specified by the protocol and so may change in future. If the limit is reached then the next XEN_NETIF_EXTRA_TYPE_MCAST_ADD sent by the frontend will be failed with NETIF_RSP_ERROR.

Anjali fixes a bug in i40e where the port is not receiving multicast or VLAN tagged packets in promiscuous mode. Which can occur when a software bridge is created on top of the device. Don adds support in ixgbe that indicates the presence of management firmware. Added support for entering low power link up state on devices that support it when the device is closing or suspending. Updated the driver to report unknown bus speed and width since IOSF does not report a PCIe bus speed or width for X550 devices. Also added the new bus type for integrated I/O interface (IOSF). Cleaned up of redundant code in ixgbe. Mark adds support for UDP-encapsulation transmit checksum and for VXLAN receive offloads. Introduces a helper function to do the register access and processing to avoid needless PHY access on copper PHYs. Added support for reporting 2.5G link speed. Fixed warnings resulting from redundant initializations of the get_bus_info field. Maninder Singh updates the ixgbe driver to use kzalloc instead of kcalloc for allocation of one thing. Tom Barbette adds support for ethtool to change the rxfh indirection table and/or key using ethtool interface. Emil resolves an issue where users were not able to dynamically set number of queues for 82598 via ethtool -L. Alex Williamson removes bimodal SR-IOV disabling behavior since it is confusing to users and results in a state where the PF is broken for other uses unless the user sets sriov_numvfs to zero prior to unbinding the device. ==================== Signed-off-by: David S.

2015-09-01ixgbe: Remove bimodal SR-IOV disablingAlex Williamson1-6/+1
When unbinding an SR-IOV device with VFs configured from ixgbe, the driver behaves in one of two ways. If max_vfs was specified, the SR-IOV state is disabled, removing the VFs. The occurs regardless of whether the VF count was later modified through sysfs. If however max_vfs is zero, such as by not specifying the module parameter, the VFs persist after the PF is unbound from ixgbe. If the PF is then bound to vfio-pci to be assigned to a VM, the PF is non-functional. >From the comment, commit da36b64736cf ("ixgbe: Implement PCI SR-IOV sysfs callback operation") clearly intended this alternate behavior, but probably didn't realize the PF doesn't work in this mode. This bimodal behavior is confusing to users and results in a state where the PF is broken for other uses unless the user sets sriov_numvfs to zero prior to unbinding the device. Remove this behavior so that VFs are removed and the PF is functional for other uses after unbind, regardless of the way VFs are enabled.

This patch removes the redundant lan_id in the phy struct and uses the bus version. Both variables exist and intend to represent the STATUS register LAN_ID field. However, phy.lan_id is not bit shifted so the phy.lan_id = 0x0 for LAN Id 0 and phy.lan_id = 0x4 for LAN Id 1. Where bus.lan_id is bit shifted so bus.lan_id = 0x0 for LAN Id 0 and bus.lan_id = 0x1 for LAN Id 1. There seems no need for the additional lan_id variable and this should make the code less confusing.

2015-09-01i40e: Set defport behavior for the Main VSI when in promiscuous modeAnjali Singhai Jain2-8/+30
This fixes bugs where the port is not receiving multicast or VLAN tagged packets when in promiscuous mode. This can occur when a SW bridge is created on top of the device. This also fixes issues where the promiscuous behavior setting was not being preserved across a reset caused by features being enabled or disabled. We are using defport instead of doing a true promiscuous mode because we do not need to receive the SRIOV or VMDq VSI directed traffic which would suck up bandwidth and is really not intended for the SW bridge.

This wasn't a problem before because the phys were not children of the bus: /sys/devices/platform/APMC0D05:00/net/eth0/xgene-mii-eth0:03 /sys/devices/platform/APMC0D05:00/net/eth0/xgene-mii-eth0 But now that they are: /sys/devices/platform/APMC0D05:00/net/eth0/xgene-mii-eth0/xgene-mii-eth0:03 when mdiobus_unregister deletes the bus device, the phy subdirs are removed from sysfs also. So when the phys are unregistered afterward, we get the warning. This patch changes the order so that phys are unregistered before the bus device is deleted.

2015-08-31net: phy: fixed_phy: Set phy capabilities even when link down.Andrew Lunn1-25/+48
What features a phy supports is masked in genphy_config_init() by looking at the PHYs BMSR register. If the link is down, fixed_phy_update_regs() will only set the auto- negotiation capable bit in BMSR. Thus genphy_config_init() comes to the conclusion the PHY can only perform 10/Half, and masks out the higher speed features. If however the link it up, BMSR is set to indicate the speed the PHY is capable of auto-negotiating, and genphy_config_init() does not mask out the high speed features. To fix this, when the link is down, have fixed_phy_update_regs() leave the link status, auto-negotiation complete, and link partner capabilities unset, but set all the local capabilities depending on the fixed phy speed.

2015-08-31net: phy: Allow PHY devices to identify themselves as Ethernet switches, etc.Florian Fainelli1-0/+1
Some Ethernet MAC drivers using the PHY library require the hardcoding of link parameters when interfaced to a switch device, SFP module, switch to switch port, etc. This has typically lead to various ad-hoc implementations looking like this: - using a "fixed PHY" emulated device, which will provide link indication towards the Ethernet MAC driver and hardware - pretend there is no PHY and hardcode link parameters, ala mv643x_eth Based on that, it is desireable to have the PHY drivers advertise the correct link parameters, just like regular Ethernet PHYs towards their CPU Ethernet MAC drivers, however, Ethernet MAC drivers should be able to tell whether this link should be monitored or not. In the context of an Ethernet switch, SFP module, switch to switch link, we do not need to monitor this link since it should be always up.
