2015-02-06ath5k: fix spontaneus AR5312 freezesSergey Ryazanov
Sometimes while CPU have some load and ath5k doing the wireless interface reset the whole WiSoC completely freezes. Set of tests shows that using atomic delay function while we wait interface reset helps to avoid such freezes. The easiest way to reproduce this issue: create a station interface, start continous scan with wpa_supplicant and load CPU by something. Or just create multiple station interfaces and put them all in continous scan. This patch partially reverts the commit 1846ac3dbec0 ("ath5k: Use usleep_range where possible"), which replaces initial udelay() by usleep_range(). I do not know actual source of this issue, but all looks like that HW freeze is caused by transaction on internal SoC bus, while wireless block is in reset state. Also I should note that I do not know how many chips are affected, but I did not see this issue with chips, other than AR5312.

2015-02-06ath9k: Fix issues with WoW enableSujith Manoharan
This patch addresses several issues with the ath9k_hw_wow_enable() routine: * The usage of set/clr variables is removed. Writing the required values to registers is cleaner. * The shift value of 28 for the contention window field in AR_WOW_PATTERN is incorrect, change it to 27. * Disabling Keep Alive needs to be done based on the LINK_CHANGE option. This is done unconditionally now, fix this. * The workaround for the D1/D3 issue is required only for AR9462. * The bitfield for enabling pattern matching for packets less than 256 bytes has expanded for new chips, handle this accordingly. * General cleanup.

2015-02-06rtlwifi: rtl8192ee: Fix problems with calculating free space in FIFOLarry Finger
This driver utilizes a FIFO buffer for RX descriptors. There are four places in the code where it calculates the number of free slots. Several of those locations do the calculation incorrectly. To fix these and to prevent future mistakes, a common inline routine is created.

2015-02-06rtlwifi: rtl8192ee: Fix handling of new style descriptorsTroy Tan
The hardware and firmware for the RTL8192EE utilize a FIFO list of descriptors. There were some problems with the initial implementation. The worst of these failed to detect that the FIFO was becoming full, which led to the device needing to be power cycled. As this condition is not relevant to most of the devices supported by rtlwifi, a callback routine was added to detect this situation. This patch implements the necessary changes in the pci handler, and the linkage into the appropriate rtl8192ee routine.

2015-02-05ixgbevf: combine all of the tasks into a single service taskEmil Tantilov
This change combines the reset and watchdog tasklets into a single task. The advantage of this is that we can avoid multiple schedules of the reset task when we have a reset event needed due to either the mailbox going down or transmit packets being present on a link down.

2015-02-05ixgbevf: Fix ordering of shutdown to correctly disable Rx and TxEmil Tantilov
This patch updates the ordering of the shutdown path so that we attempt to shutdown the rings more gracefully. Basically the big changes are that we shutdown the main Rx filter in the case of Rx and we set the carrier_off state in the case of Tx so that packets stop being delivered from outside the driver. Then we shut down interrupts and NAPI. Finally we stop the rings from performing DMA and clean them. This is a bit more graceful than the previous path.

2015-02-06cxl: Add missing return statement after handling AFU errrorIan Munsie
We were missing a return statement in the PSL interrupt handler in the case of an AFU error, which would trigger an "Unhandled CXL PSL IRQ" warning.

2015-02-06cxl: Fail AFU initialisation if an invalid configuration record is foundIan Munsie
If an AFU claims to have a configuration record but doesn't actually contain a vendor and device ID, fail the AFU initialisation.

2015-02-06cxl: Export optional AFU configuration record in sysfsIan Munsie
An AFU may optionally contain one or more PCIe like configuration records, which can be used to identify the AFU. This patch adds support for exposing the raw config space and the vendor, device and class code under sysfs. These will appear in a subdirectory of the AFU device corresponding with the configuration record number, e.g. cat /sys/class/cxl/afu0.0/cr0/vendor 0x1014 cat /sys/class/cxl/afu0.0/cr0/device 0x4350 cat /sys/class/cxl/afu0.0/cr0/class 0x120000 hexdump -C /sys/class/cxl/afu0.0/cr0/config 00000000 14 10 50 43 00 00 00 00 06 00 00 12 00 00 00 00 |..PC............| 00000010 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| * 00000100 These files behave in much the same way as the equivalent files for PCI devices, with one exception being that the config file is currently read-only and restricted to the root user. It is not necessarily required to be this strict, but we currently do not have a compelling use-case to make it writable and/or world-readable, so I erred on the side of being restrictive.
