2013-01-07brcmsmac: allow user-space setting of interface addressArend van Spriel2-4/+4

2013-01-07rt2x00: rt2800: convert read_eeprom functions to return an int valueGabor Juhos4-21/+43
Both the rtt2x00usb_eeprom_read and the ioremap functions are allowed to fail, however their return values are not checked in the read_eeprom functions in the rt2800{pci,usb} drivers. The patch adds the missing checks, and converts all read_eeprom functions to return an int value, so the error values can be propagated up to the 'rt2800_validate_eeprom' function.

Power save support was removed from iwlegacy due to possible firmware crashes problems it cause. I use to plan first inspect code to find reason of problems, fix them and then allow to enable PS.

Some 3-column initval arrays have wrong comments. The column of these arrays is indexed by the 'freqIndex' variable in 'ar5008_hw_process_ini' which only depends on the actual band. The 'initvals' tool from 'qca-swiss-army-knife' prints the correct comment lines for these arrays, since commit 'atheros-initvals: fix comments for non-fastclock 3-column tables' however the comments were not refreshed in ath9k.

2013-01-07b43: Fix firmware loading when driver is built into the kernelLarry Finger3-16/+48
Recent versions of udev cause synchronous firmware loading from the probe routine to fail because the request to user space would time out. The original fix for b43 (commit 6b6fa58) moved the firmware load from the probe routine to a work queue, but it still used synchronous firmware loading. This method is OK when b43 is built as a module; however, it fails when the driver is compiled into the kernel. This version changes the code to load the initial firmware file using request_firmware_nowait(). A completion event is used to hold the work queue until that file is available. This driver reads several firmware files - the remainder can be read synchronously. On some test systems, the async read fails; however, a following synch read works, thus the async failure falls through to the sync try.

2013-01-04wireless: add new wil6210 802.11ad 60GHz driverVladimir Kondratiev17-0/+6203
This adds support for the 60 GHz 802.11ad Wilocity card through a new driver, wil6210. Wilocity implemented the firmware, QCA maintains the device driver. Currently supported: - STA: with security - AP: limited to 1 connected STA, security disabled - Monitor: due to a hardware/firmware limitation either control or non-control frames are monitored Using a STA and AP with this drive, one can assemble a fully functional BSS. Throughput of 1.2Gbps is achieved with iperf. The wil6210 cards have on-board flash memory for the firmware, the cards comes pre-flashed and no firmware download is required.

wait_event_interruptible function returns -ERESTARTSYS if it's interrupted by a signal. Driver should check the return value and handle this case properly. In mwifiex_wait_queue_complete() routine, as we are now checking wait_event_interruptible return value, the condition check is not required. Also, we have removed mwifiex_cancel_pending_ioctl() call to avoid a chance of sending second command to FW by other path as soon as we clear current command node.

2013-01-04ath9k: Fix Kconfig for ATH9K_HTCVladimir Kondratiev1-1/+1
Ath9k consists of 2 different sub-modules: ATH9K and ATH9K_HTC. Both uses common Atheros code from ath.ko and need ATH_COMMON. However, while ATH9K selects ATH_COMMON, ATH9K_HTC does not. As result, if ATH9K_HTC is the only Atheros card selected, compilation fails with unresolved symbols.
