2016-05-16IPMI: reserve memio regions separatelyCorey Minyard
Commit d61a3ead2680 ("[PATCH] IPMI: reserve I/O ports separately") changed the way I/O ports were reserved and includes this comment in log: Some BIOSes reserve disjoint I/O regions in their ACPI tables for the IPMI controller. This causes problems when trying to register the entire I/O region. Therefore we must register each I/O port separately. There is a similar problem with memio regions on an arm64 platform (AMD Seattle). Where I see: ipmi message handler version 39.2 ipmi_si AMDI0300:00: probing via device tree ipmi_si AMDI0300:00: ipmi_si: probing via ACPI ipmi_si AMDI0300:00: [mem 0xe0010000] regsize 1 spacing 4 irq 23 ipmi_si: Adding ACPI-specified kcs state machine IPMI System Interface driver. ipmi_si: Trying ACPI-specified kcs state machine at mem \ address 0xe0010000, slave address 0x0, irq 23 ipmi_si: Could not set up I/O space The problem is that the ACPI core registers disjoint regions for the platform device: e0010000-e0010000 : AMDI0300:00 e0010004-e0010004 : AMDI0300:00 and the ipmi_si driver tries to register one region e0010000-e0010004.

2016-05-16ixgbe: Fix VLAN features errorAlexander Duyck
It looks like at some point I somehow transposed the location of setting the VLAN features in netdev->features and the configuration of the vlan_features. As a result the driver is now generating a warning about vlan_features being setup incorrectly. This patch corrects that by placing the update of netdev->features to include the VLAN features so that it is after the point where we write netdev->features into netdev->vlan_features.

2016-05-16PCI: Disable all BAR sizing for devices with non-compliant BARsPrarit Bhargava
b84106b4e229 ("PCI: Disable IO/MEM decoding for devices with non-compliant BARs") disabled BAR sizing for BARs 0-5 of devices that don't comply with the PCI spec. But it didn't do anything for expansion ROM BARs, so we still try to size them, resulting in warnings like this on Broadwell-EP: pci 0000:ff:12.0: BAR 6: failed to assign [mem size 0x00000001 pref] Move the non-compliant BAR check from __pci_read_base() up to pci_read_bases() so it applies to the expansion ROM BAR as well as to BARs 0-5. Note that direct callers of __pci_read_base(), like sriov_init(), will now bypass this check. We haven't had reports of devices with broken SR-IOV BARs yet.

2016-05-16qed: Allow more than 16 VFsYuval Mintz
In multi-function modes, PFs are currently limited to using 16 VFs - But that limitation would also currently apply in case there's a single PCI function exposed, where no such restriction should have existed. This lifts the restriction for the default mode; User should be able to start the maximum number of VFs as appear in the PCI config space.

2016-05-16qed: Reset link on IOV disableManish Chopra
PF updates its VFs' bulletin boards with link configurations whenever the physical carrier changes or whenever hyper-user explicitly requires some setting of the VFs link via the hypervisor's PF. Since the bulletin board is getting cleaned as part of the IOV disable flow on the PF side, re-enabling sriov would lead to a VF that sees the carrier as 'down', until an event causing the PF to re-fill the bulletin with the link configuration would occur. To fix this we simply refelect the link state during the flows, giving the later VFs a default reflecting the PFs link state.

2016-05-16net: w5100: increase TX timeout periodAkinobu Mita
This increases TX timeout period from one second to 5 seconds which is the default value if the driver doesn't explicitly set net_device->watchdog_timeo. The one second timeout is too short for W5100 with SPI interface mode which doesn't support burst READ/WRITE processing in the SPI transfer. If the packet is transmitted while RX packets are being received at a very high rate, the TX transmittion work in the workqueue is delayed and the watchdog timer is expired.

2016-05-16net: dsa: mv88e6xxx: remove bridge workVivien Didelot
Now that the bridge code defers the switchdev port state setting, there is no need to defer the port STP state change within the mv88e6xxx code. Thus get rid of the driver's bridge work code. This also fixes a race condition where the DSA layer assumes that the bridge code already set the unbridged port's STP state to Disabled before restoring the Forwarding state. As a consequence, this also fixes the FDB flush for the unbridged port which now correctly occurs during the Forwarding to Disabled transition.

One cpu can be processing packets which includes using the cached route entries in the vrf device's private data and on another cpu the device gets deleted which releases the routes and sets the pointers in net_vrf to NULL.

2016-05-16net/mlx5_core: Flow counters infrastructureAmir Vadai
If a counter has the aging flag set when created, it is added to a list of counters that will be queried periodically from a workqueue. query result and last use timestamp are cached. add/del counter must be very efficient since thousands of such operations might be issued in a second. There is only a single reference to counters without aging, therefore no need for locks. But, counters with aging enabled are stored in a list. In order to make code as lockless as possible, all the list manipulation and access to hardware is done from a single context - the periodic counters query thread. The hardware supports multiple counters per FTE, however currently we are using one counter for each FTE. Signed-off-by: Amir Vadai <amirva@mellanox.com> Signed-off-by: David S.
