2016-05-25net: stmmac: Fix incorrect memcpy source memoryMarek Vasut
The memcpy() currently copies mdio_bus_data into new_bus->irq, which makes no sense, since the mdio_bus_data structure contains more than just irqs. The code was likely supposed to copy mdio_bus_data->irqs into the new_bus->irq instead, so fix this.

2016-05-25net: alx: use custom skb allocatorFeng Tang
This patch follows Eric Dumazet's commit 7b70176421 for Atheros atl1c driver to fix one exactly same bug in alx driver, that the network link will be lost in 1-5 minutes after the device is up. My laptop Lenovo Y580 with Atheros AR8161 ethernet device hit the same problem with kernel 4.4, and it will be cured by Jarod Wilson's commit c406700c for alx driver which get merged in 4.5. But there are still some alx devices can't function well even with Jarod's patch, while this patch could make them work fine. More details on https://bugzilla.kernel.org/show_bug.cgi?id=70761 The debug shows the issue is very likely to be related with the RX DMA address, specifically 0x...f80, if RX buffer get 0x...f80 several times, their will be RX overflow error and device will stop working. For kernel 4.5.0 with Jarod's patch which works fine with my AR8161/Lennov Y580, if I made some change to the __netdev_alloc_skb --> __alloc_page_frag() to make the allocated buffer can get an address with 0x...f80, then the same error happens. If I make it to 0x...f40 or 0x....fc0, everything will be still fine. So I tend to believe that the 0x..f80 address cause the silicon to behave abnormally.

2016-05-24net/qlge: Avoids recursive EEH errorGavin Shan
One timer, whose handler keeps reading on MMIO register for EEH core to detect error in time, is started when the PCI device driver is loaded. MMIO register can't be accessed during PE reset in EEH recovery. Otherwise, the unexpected recursive error is triggered. The timer isn't closed that time if the interface isn't brought up. So the unexpected recursive error is seen during EEH recovery when the interface is down. This avoids the unexpected recursive EEH error by closing the timer in qlge_io_error_detected() before EEH PE reset unconditionally. The timer is started unconditionally after EEH PE reset in qlge_io_resume(). Also, the timer should be closed unconditionally when the device is removed from the system permanently in qlge_io_error_detected(). Reported-by: Shriya R.

2016-05-18net/mlx5_core: Use tasklet for user-space CQ completion eventsMatan Barak
Previously, we've fired all our completion callbacks straight from our ISR. Some of those callbacks were lightweight (for example, mlx5 Ethernet napi callbacks), but some of them did more work (for example, the user-space RDMA stack uverbs' completion handler). Besides that, doing more than the minimal work in ISR is generally considered wrong, it could even lead to a hard lockup of the system. Since when a lot of completion events are generated by the hardware, the loop over those events could be so long, that we'll get into a hard lockup by the system watchdog. In order to avoid that, add a new way of invoking completion events callbacks. In the interrupt itself, we add the CQs which receive completion event to a per-EQ list and schedule a tasklet. In the tasklet context we loop over all the CQs in the list and invoke the user callback. Signed-off-by: Matan Barak <matanb@mellanox.com> Signed-off-by: Doug Ledford <dledford@redhat.com>

2016-05-17r8169: default to 64-bit DMA on recent PCIe chipsArd Biesheuvel
The current logic around the 'use_dac' module parameter prevents the r81969 driver from being loadable on 64-bit systems without any RAM below 4 GB when the parameter is left at its default value. So introduce a new default value -1 which indicates that 64-bit DMA should be enabled on sufficiently recent PCIe chips, i.e., versions RTL_GIGA_MAC_VER_18 or later. Explicit param values of 0 or 1 retain the existing behavior of unconditionally enabling/disabling 64-bit DMA on 64-bit architectures (i.e., regardless of the type and version of the chip) Since PCIe chips do not need to CPlusCmd Dual Address Cycle to be set, make that conditional on the device type as well.

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.

2016-05-16qed: 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.
