      e1000e: Fix issue with link flap on 82579 · 7142a55c
      David Ertman 提交于
      Several customers have reported a link flap issue on 82579. The symptoms
      are random and intermittent link losses when 82579 is connected to specific
      link partners. Issue has been root caused as interoperability problem
      between 82579 and at least some Broadcom PHYs in the Energy Efficient
      Ethernet wake mechanism.
      
      To fix the issue, we are disabling the Phase Locked Loop shutdown in 100M
      Low Power Idle.  This solution will cause an increase of power in 100M EEE
      link. It will cost additional 28mW in this specific mode.

      e1000e: Expand workaround for 10Mb HD throughput bug · fbb9ab10
      David Ertman 提交于
      In commit 772d05c5 "e1000e: slow performance
      between two 82579 connected via 10Mbit hub", a workaround was put into place
      to address the overaggressive transmit behavior of 82579 parts when connecting
      at 10Mbs half-duplex.
      
      This same behavior is seen on i217 and i218 parts as well.  This patch expands
      the original workaround to encompass these parts.

      e1000e: Workaround for dropped packets in Gig/100 speeds on 82579 · 77e61146
      David Ertman 提交于
      This is a workaround for a HW erratum on 82579 devices.
      Erratum is #23 in Intel 6 Series Chipset and Intel C200 Series Chipset
      specification Update June 2013.
      
      Problem: 82579 parts experience packet loss in Gig and 100 speeds
      when interconnect between PHY and MAC is exiting K1 power saving state.
      This was previously believed to only affect 1Gig speed, but has been observed
      at 100Mbs also.
      
      Workaround: Disable K1 for 82579 devices at Gig and 100 speeds.

      vsock: Make transport the proto owner · 2c4a336e
      Andy King 提交于
      Right now the core vsock module is the owner of the proto family. This
      means there's nothing preventing the transport module from unloading if
      there are open sockets, which results in a panic. Fix that by allowing
      the transport to be the owner, which will refcount it properly.
      
      Includes version bump to 1.0.1.0-k

      ====================
      pull request: wireless 2014-05-01
      
      Please pull the following batch of fixes intended for the 3.15 stream!
      
      For the Bluetooth bits, Gustavo says:
      
      "Some fixes for 3.15. There is a revert for the intel driver, a new
      device id, and two important SSP fixes from Johan."
      
      On top of that...
      
      Ben Hutchings gives us a fix for an unbalanced irq enable in an
      rtl8192cu error path.
      
      Colin Ian King provides an rtlwifi fix for an uninitialized variable.
      
      Felix Fietkau brings a pair of ath9k fixes, one that corrects a
      hardware initialization value and another that removes an (unnecessary)
      flag that was being used in a way that led to a software tx queue
      hang in ath9k.
      
      Gertjan van Wingerde pushes a MAINTAINERS change to remove himself
      from the rt2x00 maintainer team.
      
      Hans de Goede fixes a brcmfmac firmware load hang.
      
      Larry Finger changes rtlwifi to use the correct queue for V0 traffic
      on rtl8192se.
      
      Rajkumar Manoharan corrects a race in ath9k driver initialization.
      
      Stanislaw Gruszka fixes an rt2x00 bug in which disabling beaconing
      once on USB devices led to permanently disabling beaconing for those
      devices.
      
      Tim Harvey provides fixes for a pair of ath9k issues that can lead
      to soft lockups in that driver.
      
      Please let me know if there are problems!

      ath9k: remove tid->paused flag · 62e54dbb
      Felix Fietkau 提交于
      There are some corner cases where the driver could get stuck with a full
      tid queue that is paused, leading to a software tx queue hang.
      
      Since the tx queueing rework, pausing per-tid queues on aggregation
      session setup is no longer necessary. The driver will assign sequence
      numbers to buffered frames when a new session is established, in order
      to get the correct starting sequence number.
      
      mac80211 prevents new frames from entering the queue during setup.

      ath9k_hw: do not lower ANI setting below default on AR913x · ae9c25a1
      Felix Fietkau 提交于
      When the amount of noise fluctuates strongly, low immunity settings
      can sometimes disrupt signal detection on AR913x chips. When that
      happens, no OFDM/CCK errors are reported anymore, and ANI tunes the
      radio to the lowest immunity settings.
      Usually rx/tx fails as well in that case.
      
      To fix this, keep noise immunity settings at or above ANI default level,
      which will keep radio parameters at or above INI values.
