To correct this, add a counter and give up trying to get the lock after fifty tries. Log a message if this happens but don't take any other action. Because this happens after a reset, all of the Rx filters are still in place and the device won't lose connectivity. We can also get stuck during shutdown, if the PF has stopped communicating with us, or if a reset is occurring. If we can't get the lock after a reasonable amount of time, just error out. Something else bad is happening anyway, so adding this filter is the least of our concern right now.

Since i40evf_down now holds the critical section lock, we cannot call it from the reset handler, which also holds the lock. To do so causes a deadlock accompanied by wailing and gnashing of teeth. This is easily triggered by running an ethtool self-test on the PF device. Instead, we move the relevant portions of i40evf_down into the reset handler and bend them to our will. Additionally, we can optimize the reinit path by not deleting the MAC and VLAN filters and then adding them back again. Instead, we just set the 'add' flag and let the watchdog resynchronize the filter list with the PF driver. We also reword a few messages to make them more consistent with the rest of the driver.

This patch repositions I40E_VIRTCHNL_OP_CONFIG_RSS to the end of the enum. In its current position this opcode displaces the initial value of I40E_VIRTCHNL_OP_EVENT and will cause PF/VF compatibility issues. Going forward the expectation is either: a) All future opcode additions will be added as the last element of the enum. Once VF drivers start making use of the new commands the virtual channel version will need to be incremented and drivers will need to implement a simple version check whereby VF drivers can only load on PFs with a >= version. b) or, if needed, design and implement a more complicated API negotiation capability. In either case PF drivers should always maintain backwards compatibility with earlier VF driver versions.

This improves receive performance since we only need to check if the ring is in packet split mode once per NAPI poll time, not several times per packet. The single buffer code is further improved by the removal of a bunch of code and several variables that are not needed. On a receive-oriented test this can improve single-threaded throughput. Also refactor the packet split receive path to use a fixed buffer for headers, like ixgbe does. This vastly reduces the number of DMA mappings and unmappings we need to do, allowing for much better performance in the presence of an IOMMU. Lastly, correct packet split descriptor types now that we are actually using them.

First off, we have new callbacks for PM domains that should help us to handle some issues related to device initialization in a better way. There also is some consolidation in the unified device properties API area allowing us to use that inferface for accessing data coming from platform initialization code in addition to firmware-provided data. We have some new device/CPU IDs in a few drivers, support for new chips and a new cpufreq driver too. Specifics: - Generic PM domains support update including new PM domain callbacks to handle device initialization better (Russell King, Rafael J Wysocki, Kevin Hilman) - Unified device properties API update including a new mechanism for accessing data provided by platform initialization code (Rafael J Wysocki, Adrian Hunter) - ARM cpuidle update including ARM32/ARM64 handling consolidation (Daniel Lezcano) - intel_idle update including support for the Silvermont Core in the Baytrail SOC and for the Airmont Core in the Cherrytrail and Braswell SOCs (Len Brown, Mathias Krause) - New cpufreq driver for Hisilicon ACPU (Leo Yan) - intel_pstate update including support for the Knights Landing chip (Dasaratharaman Chandramouli, Kristen Carlson Accardi) - QorIQ cpufreq driver update (Tang Yuantian, Arnd Bergmann) - powernv cpufreq driver update (Shilpasri G Bhat) - devfreq update including Tegra support changes (Tomeu Vizoso, MyungJoo Ham, Chanwoo Choi) - powercap RAPL (Running-Average Power Limit) driver update including support for Intel Broadwell server chips (Jacob Pan, Mathias Krause) - ACPI device enumeration update related to the handling of the special PRP0001 device ID allowing DT-style 'compatible' property to be used for ACPI device identification (Rafael J Wysocki) - ACPI EC driver update including limited _DEP support (Lan Tianyu, Lv Zheng) - ACPI backlight driver update including a new mechanism to allow native backlight handling to be forced on non-Windows 8 systems and a new quirk for Lenovo Ideapad Z570 (Aaron Lu, Hans de Goede) - New Windows Vista compatibility quirk for Sony VGN-SR19XN (Chen Yu) - Assorted ACPI fixes and cleanups (Aaron Lu, Martin Kepplinger, Masanari Iida, Mika Westerberg, Nan Li, Rafael J Wysocki) - Fixes related to suspend-to-idle for the iTCO watchdog driver and the ACPI core system suspend/resume code (Rafael J Wysocki, Chen Yu) - PM tracing support for the suspend phase of system suspend/resume transitions (Zhonghui Fu) - Configurable delay for the system suspend/resume testing facility (Brian Norris) - PNP subsystem cleanups (Peter Huewe, Rafael J Wysocki)" * tag 'pm+acpi-4.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (74 commits) ACPI / scan: Fix NULL pointer dereference in acpi_companion_match() ACPI / scan: Rework modalias creation when "compatible" is present intel_idle: mark cpu id array as __initconst powercap / RAPL: mark rapl_ids array as __initconst powercap / RAPL: add ID for Broadwell server intel_pstate: Knights Landing support intel_pstate: remove MSR test cpufreq: fix qoriq uniprocessor build ACPI / scan: Take the PRP0001 position in the list of IDs into account ACPI / scan: Simplify acpi_match_device() ACPI / scan: Generalize of_compatible matching device property: Introduce firmware node type for platform data device property: Make it possible to use secondary firmware nodes PM / watchdog: iTCO: stop watchdog during system suspend cpufreq: hisilicon: add acpu driver ACPI / EC: Call acpi_walk_dep_device_list() after installing EC opregion handler cpufreq: powernv: Report cpu frequency throttling intel_idle: Add support for the Airmont Core in the Cherrytrail and Braswell SOCs intel_idle: Update support for Silvermont Core in Baytrail SOC PM / devfreq: tegra: Register governor on module init ...
