Enables support for Dynack feature.
When a remote station is far away, we need to compensate for the distance
by allowing more time for an ACK to arrive back before issueing a retransmission.
Currently, it needs to be set fixed to indicate the maximum distance the remote
station will ever be.
While this mostly works for static antennae, it introduces 2 issues:
- If the actual distance is less, speed is reduced due to a lot of wates wait-time
- If the distance becomes greater, retries start to occur and comms can get lost.
Allowing to set it dynamically using dynack ensures the best possible tradeoff
between speed vs distance.
This feature is currently only supported in ath9k.
it is also disabled by default.
Enabling it can be done in 2 ways:
- issue cmd: iw phy0 set distance auto
- sending the NL80211_ATTR_WIPHY_DYN_ACK flag to mac80211 driver using netlink
Disabling it can be done by providing a valid fixed value.
To give an idea of a practical example:
In my usecase, we have mesh wifi device installed on ships/platforms.
Currently, the coverage class is set at 12000m fixed.
When a vessel moved closer (ex. 1500m), the measured link capacity was a lot
lower compared to setting the coverage class fixed to 1500m
Dynack completely solved this, nearly providing double the bandwidth at closer range
compared to the fixed setting of 12000m being used.
Also when a vessel sailed to a distance greater than the fixed setting,
communication was lost as the ACK's never arrived within the max allowed timeframe.
Actual distance: 6010m
iperf 60s run avg
Fixed 12150m: 31 Mbit/s
Dynack: 58 Mbit/s
Fixed 6300m: 51 Mbit/s
Dynack: 59 Mbit/s
Fixed 3000m: 13 Mbit/s (lots of retries)
Dynack: 58 Mbit/s
Actual distance: 1504m

Most of the implementations behind cfg80211_get_station will not initialize
sinfo to zero before manipulating it. For example, the member "filled",
which indicates the filled in parts of this struct, is often only modified
by enabling certain bits in the bitfield while keeping the remaining bits
in their original state. A caller without a preinitialized sinfo.filled can
then no longer decide which parts of sinfo were filled in by
cfg80211_get_station (or actually the underlying implementations).
cfg80211_get_station must therefore take care that sinfo is initialized to
zero. Otherwise, the caller may tries to read information which was not
filled in and which must therefore also be considered uninitialized. In
batadv_v_elp_get_throughput's case, an invalid "random" expected throughput
may be stored for this neighbor and thus the B.A.T.M.A.N V algorithm may
switch to non-optimal neighbors for certain destinations.

Commit 61d57a2f88 adds ath10k LED
support, but doesn't add an option to actually enable it.
After enabling this option, a LED named ath10k-phy0 appears in sysfs,
and a trigger can be assigned to it. Since 60deb3cdef the default set
trigger is the tpt one.
Enable it by default, as most devices using ath10k chips shouldn't be
severely space-constrained. There are likely many devices that can
benefit from having it enabled, like my testing device.

Some ath10k firmware versions allow to access the chip internal a
temperature sensor and allow to reduce the amount of the time when the card
is allowed to send. The latter is required on devices which tend to
overheat.
An userspace service has to read
/sys/class/ieee80211/phy*/device/hwmon/hwmon*/temp1_input regularly and
then decide how much the device has to be throttled. This can be done by
writing to /sys/class/ieee80211/phy*/device/cooling_device/cur_state. By
default it is not throttled (0) but it can be throttled up to 100(%).

|From: Thomas Hebb <tommyhebb@gmail.com>
|Subject: [PATCH] ath10k: search all IEs for variant before falling back
|Date: Wed, 21 Feb 2018 11:43:39 -0500
|[...]
|This patch fixes the issue by first searching the entire file for the ID
|with variant, and searching for the fallback ID only if that search
|fails. It also includes some code cleanup in the area, as
|ath10k_core_fetch_board_data_api_n() no longer does its own string
|mangling to remove the variant from an ID, instead leaving that job to a
|new flag passed to ath10k_core_create_board_name().
|
|I've tested this patch on a QCA4019 and verified that the driver behaves
|correctly for 1) both fallback and variant BDFs present, 2) only fallback
|BDF present, and 3) no matching BDFs present.
