2016-09-24i40evf: support queue-specific settings for interrupt moderationJacob Keller
In commit a75e8005d506f3 ("i40e: queue-specific settings for interrupt moderation") the i40e driver gained support for setting interrupt moderation values per queue. This patch adds support for this feature to the i40evf driver as well. In addition, a few changes are made to the i40e implementation to add function header documentation comments, as well. This behaves in a similar fashion to the implementation in i40e. Thus, requesting the moderation value when no queue is provided will report queue 0 value, while setting the value without a queue will set all queues at once.

The Tx cleanup flow was incorrectly assuming it could check for the flow director bits after it had unmapped the buffer. However in this case it results in us trying to free a raw_buf as though it is an sk_buff. To fix this I am moving up the flag test for the FD_SB bit so that when find a non-NULL skb or raw_buf value we then check the flag and use the appropriate call to free the buffer.

2016-09-24i40e: Increase minimum number of allocated VSIAkeem Abodunrin
This patch increases minimum number of allocated VSIs, so as to resolve failure adding VSI for VF when 64-VFs assigned to a PF. The driver supports up to 128 VFs per device, users can decide to enable up to 64-VFs on a single PF, especially 2 X 40 devices. In that scenario, with VMDq co-existence, there would be starvation of VSIs - with this patch, supported features would have enough VSIs for configuration now.

2016-09-24i40e: check conflicting ntuple/sideband rules when re-enabling ATRJacob Keller
In i40e_fdir_check_and_reenable(), the driver performs some checks to determine whether it is safe to re-enable FD Sideband and FD ATR support. The current check will only determine if there is available space in the flow director table. However, this ignores the fact that ATR should be disabled when there are TCP/IPv4 sideband rules in effect. Add the missing check, and update the info message printed when I40E_DEBUG_FD is enabled.

2016-09-24i40e: cleanup ATR auto_disable_flags useJacob Keller
Some locations that disable ATR accidentally used the "full" disable by disabling the flag in the standard flags field. This incorrectly forces ATR off permanently instead of temporarily disabling it. In addition, some code locations accidentally set the ATR flag enabled when they only meant to clear the auto_disable_flags. This results in ignoring the user's ethtool private flag settings. Additionally, when disabling ATR via ethtool, we did not perform a flush of the FD table. This results in the previously assigned ATR rules still functioning which was not expected. Cleanup all these areas so that automatic disable uses only the auto_disable_flag. Fix the flush code so that we can trigger a flush even when we've disabled ATR and SB support, as otherwise the flush doesn't work. Fix ethtool setting to actually request a flush. Fix NETIF_F_NTUPLE flag to only clear the auto_disable setting and not enable the full feature.

2016-09-24i40e: fix deleting mac filtersAlan Brady
There exists a bug in which deleting a mac filter does not actually occur. The driver reports that the filter has been deleted with no error. The problem occurs because the wrong cmd_flag is passed to the firmware when deleting the filter. The firmware reports an error back to the driver but it is expressly ignored. This fixes the bug by using the correct flag when deleting a filter. Without this patch, deleted filters remain in firmware and function as if they had not been deleted.

2016-09-24regulator: core: don't return error with inadequate reasonJoonwoo Park
drms_uA_update() always returns failure when it cannot find regulator's input voltage. But if hardware supports load configuration with ops->set_load() and the input regulator isn't specified with valid reason such as the input regulator is battery, not finding input voltage is normal so such case should not return with an error. Avoid such inadequate error return by checking input/output voltages only when drms_uA_update() is about to configure load with enum based ops->set_mode().

Description: When DCDC CLK SYNC bits are 11/01: * VIO 3-MHz oscillator is the source clock of the digital core and input clock of VDD1 and VDD2 * Turn-on of VDD1 and VDD2 HSD PFETis synchronized or at a constant phase shift * Current pulled though VCC1+VCC2 is Iload(VDD1) + Iload(VDD2) * The 3 HSD PFET will be turned-on at the same time, causing the highest possible switching noise on the application. This noise level depends on the layout, the VBAT level, and the load current. The noise level increases with improper layout. When DCDC CLK SYNC bits are 00: * VIO 3-MHz oscillator is the source clock of digital core * VDD1 and VDD2 are running on their own 3-MHz oscillator * Current pulled though VCC1+VCC2 average of Iload(VDD1) + Iload(VDD2) * The switching noise of the 3 SMPS will be randomly spread over time, causing lower overall switching noise.

Emil provides several changes, first simplifies the logic for setting VLAN filtering by checking the VMDQ flag and the old 82598 MAC, instead of having to maintain a list of MAC types. Then made two functions static that are used only within the file, a by-product is sparse is now happy. Added spinlocks to make sure that the MTU configuration is handled properly. Fixed an issue where when SR-IOV is enabled while the ixgbevf driver is loaded would result in all mailbox requests being rejected by ixgbe, so call ixgbe_sriov_reinit() before pci_enable_sriov() to ensure mailbox requests are properly handled. Mark resolves a NULL pointer issue by simply setting the read and write *_ref_mdi pointers for x550em_a devices. Then clearly indicates within ethtool that all MACs support pause frames and made sure that the advertising is set to the requested mode. Fixed an issue where MDIO_PRTAD_NONE was not being used consistently to indicate no PHY address. Alex fixes an issue, where the support for multiple queues when SR-IOV is enabled was added but the support was not reported. With that, fix an issue where the hardware redirection table could support more queues then the PF currently has when SR-IOV is enabled, so use the RSS mask to trim off the bits that are not used. Lastly, instead of limiting the VFs if we do not use 4 queues for RSS in the PF, we can instead just limit the RSS queues used to a power of 2. We can now support use cases where VFs are using more queues than the PF is currently using and can support RSS if so desired. ==================== Signed-off-by: David S.

Sridhar fixes link state event handling by updating the carrier and starts/stops the Tx queues based on the link state notification from PF. Brady fixes an issue where a user defined RSS hash key was not being set because a user defined indirection table is not supplied when changing the hash key, so if an indirection table is not supplied now, then a default one is created and the hash key is correctly set. Also fixed an issue where when NPAR was enabled, we were still using pf->mac_seid to perform the dump port query. Instead, go through the VSI to determine the correct ID to use in either case. Mitch provides one fix where a conditional return code was reversed, so he does a "switheroo" to fix the issue. Carolyn has two fixes, first fixes an issue in the virt channel code, where a return code was not checked for NULL when applicable. Second, fixes an issue where we were byte swapping the port parameter, then byte swapping it again in function execution. Colin Ian King fixes a potential NULL pointer dereference. Bimmy changes up i40evf_up_complete() to be void since it always returns success anyways, which allows cleaning up of code which checked the return code from this function. Alex fixed an issue where the driver was incorrectly assuming that we would always be pulling no more than 1 descriptor from each fragment. So to correct this, we just need to make certain to test all the way to the end of the fragments as it is possible for us to span 2 descriptors in the block before us so we need to guarantee that even the last 6 descriptors have enough data to fill a full frame. v2: dropped patches 1-3, 10 and 12 from the original series since Or Gerlitz pointed out several areas of improvement in the implementation of the VF Port representor netdev.

2016-09-24net/mlx4: Add VF vlan protocol 802.1ad supportMoshe Shemesh
Move the vf to VST 802.1ad mode (mlx4 VST QinQ mode) by setting vf vlan protocol to 802.1ad. VST 802.1ad mode in mlx4, is used for STAG strip/insertion by PF, while the CTAG is set by the VF. Read current vlan protocol as part of the vf configuration state. Upon setting vf vlan protocol to 802.1ad, we use a mechanism of handshake to verify that both the vf and the pf driver version support it. The handshake uses the command QUERY_FUNC_CAP: - The vf sets a pre-defined support bit in input modifier. - A pf that supports the feature sends the request to the vf through a pre-defined field in the output mailbox. - In case vf does not support the feature, the pf will fail the control command (in this case, IP link tool command to set the vf vlan protocol to 802.1ad).

Introduce new rtnl UAPI that exposes a list of vlans per VF, giving the ability for user-space application to specify it for the VF, as an option to support 802.1ad. We adjusted IP Link tool to support this option. For future use cases, the new UAPI supports multiple vlans. For now we limit the list size to a single vlan in kernel. Add IFLA_VF_VLAN_LIST in addition to IFLA_VF_VLAN to keep backward compatibility with older versions of IP Link tool. Add a vlan protocol parameter to the ndo_set_vf_vlan callback. We kept 802.1Q as the drivers' default vlan protocol. Suitable ip link tool command examples: Set vf vlan protocol 802.1ad: ip link set eth0 vf 1 vlan 100 proto 802.1ad Set vf to VST (802.1Q) mode: ip link set eth0 vf 1 vlan 100 proto 802.1Q Or by omitting the new parameter ip link set eth0 vf 1 vlan 100 Signed-off-by: Moshe Shemesh <moshe@mellanox.com> Signed-off-by: Tariq Toukan <tariqt@mellanox.com> Signed-off-by: David S.

2016-09-24net/mlx4_core: Fix QUERY FUNC CAP flagsMoshe Shemesh
Separate QUERY_FUNC_CAP flags0 from QUERY_FUNC_CAP flags, as 'flags' is already used for another set of flags in FUNC CAP, while phv bit should be part of a different set of flags. Remove QUERY_FUNC_CAP port_flags field, as it is not in use.

2016-09-24Bluetooth: BCSP fails to ACK re-transmitted frames from the peerDean Jenkins
Send an ACK frame with the current txack value in response to every received reliable frame unless a TX reliable frame is being sent. This modification allows re-transmitted frames from the remote peer to be acknowledged rather than ignored. It means that the remote peer knows which frame number to start re-transmitting from. Without this modification, the recovery time to a missing frame from the remote peer was unnecessarily being extended because the headers of the out of order reliable frames were being discarded rather than being processed. The frame headers of received frames will indicate whether the local peer's transmissions have been acknowledged by the remote peer. Therefore, the local peer may unnecessarily re-transmit despite the remote peer already indicating that the frame had been acknowledged in out of order reliable frame.

2016-09-24ACPICA: Parser: Fix a regression in LoadTable supportLv Zheng
ACPICA commit a78506e0ce8ab1d20db2a055d99cf9143e89eb29 LoadTable allows an alternative RootPathString than the default "\", while the new table execution support fails to keep this logic. This regression can be detected by ASLTS - TLT0.tst4, this patch fixes this regression. Linux upstream is not affected by this regression as we haven't enabled the new table execution support there.

2016-09-24ACPI / watchdog: Add support for WDAT hardware watchdogMika Westerberg
Starting from Intel Skylake the iTCO watchdog timer registers were moved to reside in the same register space with SMBus host controller. Not all needed registers are available though and we need to unhide P2SB (Primary to Sideband) device briefly to be able to read status of required NO_REBOOT bit. The i2c-i801.c SMBus driver used to handle this and creation of the iTCO watchdog platform device. Windows, on the other hand, does not use the iTCO watchdog hardware directly even if it is available. Instead it relies on ACPI Watchdog Action Table (WDAT) table to describe the watchdog hardware to the OS. This table contains necessary information about the the hardware and also set of actions which are executed by a driver as needed. This patch implements a new watchdog driver that takes advantage of the ACPI WDAT table. We split the functionality into two parts: first part enumerates the WDAT table and if found, populates resources and creates platform device for the actual driver. The second part is the driver itself. The reason for the split is that this way we can make the driver itself to be a module and loaded automatically if the WDAT table is found. Otherwise the module is not loaded. Signed-off-by: Mika Westerberg <mika.westerberg@linux.intel.com> Reviewed-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Rafael J.
