      e1000e: Fix issue with link flap on 82579 · 7142a55c
      由 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
      由 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
      由 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.

      ath9k: remove tid->paused flag · 62e54dbb
      由 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
      由 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.
