Accurate RX timestamp reporting is important for proper IBSS merging, mesh synchronization, and MCCA scheduling. Namely, knowing where the TSF is recorded is needed to sync with the beacon timestamp field. Tested with AR9271. Signed-off-by:

The calibration data for devices w/o a separate EEPROM chip can be specified via the 'eeprom_data' field of 'ath9k_platform_data'. The 'eeprom_data' is usually filled from board specific setup functions. It is easy if the EEPROM data is mapped to the memory, but it can be complicated if it is stored elsewhere. The patch adds support for loading of the EEPROM data via the firmware API to avoid this limitation. Signed-off-by:

The 'ath9k_hw_nvram_read' function takes a 'struct ath_common *' as its first argument. Almost each of its caller has a 'struct ath_hw *' parameter in their argument list, and that is dereferenced in order to get the 'struct ath_common' pointer. Change the first argument of 'ath9k_hw_nvram_read' to be a 'struct ath_hw *', and remove the dereference calls from the callers. Also change the type of the first argument of the ar9300_eeprom_read_{byte,word} functions. Signed-off-by: -

The fill_eeprom functions are printing the same debug message in case the 'ath9k_hw_nvram_read' function fails. Remove the duplicated code from fill_eeprom functions and add the ath_dbg call directly into 'ath9k_hw_nvram_read'. Signed-off-by:

While AR_PHY_CCA_NOM_VAL_* does contain the expected internal noise floor for a chip measured in clean air, it refers to the lowest expected reading. Depending on the frequency, this measurement can vary by about 6db, thus causing a higher reported channel noise and signal strength. Factor in the 6db offset when converting internal noisefloor to channel noise. This patch makes the reported values more accurate for all chips without affecting NF calibration behavior.

We were using wrong IRQ number so clearing wasn't working at all. Depending on a platform this could result in a one device having two interrupts assigned. On BCM4706 this resulted in all IRQs being broken. Cc: Hauke Mehrtens <hauke@hauke-m.de> Cc: stable@vger.kernel.org Signed-off-by:

D-Link DWA-125/B1 is a relatively new USB Wi-Fi adapter, using a Ralink chipset supported by the rt2800usb driver. Currently, to work around the problem (it's missing in all present kernel versions, up to and including 3.7.x), I had to add this to /etc/rc.local: echo 2001 3c1e >> /sys/bus/usb/drivers/rt2800usb/new_id After that, the device works without problems. Been using it for over a week with no bugs in sight. The attached patch is trivial and simply adds the new USB ID to the list of devices handled by rt2800usb. Signed-off-by:

This patch fixes a regression which was introduced by: "carl9170: split up carl9170_handle_mpdu" Previously, the ieee80211_rx_status was kept on the stack of carl9170_handle_mpdu. Now it's passed into the function as a pointer parameter. Hence, the old memcpy call needs to be fixed. Signed-off-by:

As described in the documentation of bcma_wflush16 in drivers/net /wireless/brcm80211/brcmsmac/types.h some PCIe controllers of Broadcom SoCs are broken. The PCIe controller on these SoCs are mostly used to connect some additional wifi device to the SoC and some of these wifi devices are supported by brcmsmac. For my BCM43224 connected to the broken PCIe controller of the BCM4718 I need an extra read after write in brcms_b_write_objmem() to prevent a Data bus error. This fixes the problem reading tsf_random later. Signed-off-by:

Commit "ath9k: Fix the 'xmit' debugfs file" changed the the array size of ath_stats.txstats to IEEE80211_NUM_ACS, which is wrong because the HW queue number is used to update the statistics. Revert back to using ATH9K_NUM_TX_QUEUES. Reported-by:

Recent versions of udev cause synchronous firmware loading from the probe routine to fail because the request to user space times out. The original fix for b43legacy (commit a3ea2c76) moved the firmware load from the probe routine to a work queue, but it still used synchronous firmware loading. This method is OK when b43legacy 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. The remaining firmware files are read synchronously. Signed-off-by:

This adds support for bcma wifi core revision 17 which is found on BCM4716/4717/4718 SoCs. The firmware version 610.812 for brcmsmac found in linux-firmware does not support these cores, but a firmware generated with b43-fwcutter from the proprietary broadcom wireless driver works with these chips. This wifi core contains a revision 5 N-PHY and a revision 7 radio of type 0x2056. Signed-off-by:

This reverts commit f74b9d36. Turns out reverting commit a240dc7b "ath9k_hw: Updated AR9003 tx gain table for 5GHz" was not enough to bring the tx power back to normal levels on devices like the Buffalo WZR-HP-G450H, this one needs to be reverted as well. This revert improves tx power by ~10 db on that device Signed-off-by:
