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
iperf 60s run avg
Fixed 12150m: 31 Mbit/s
Dynack: 86 Mbit/s
Fixed 6300m: 55 Mbit/s
Dynack: 87 Mbit/s
Fixed 3000m: 67 Mbit/s
Dynack: 87 Mbit/s

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.

Board Data File (BDF) is loaded upon driver boot-up procedure. The right
board data file is identified on QCA4019 using bus, bmi-chip-id and
bmi-board-id.
The problem, however, can occur when the (default) board data file cannot
fulfill the vendor requirements and it is necessary to use a different
board data file.
This problem was solved for SMBIOS by adding a special SMBIOS type 0xF8.
Something similar has to be provided for systems without SMBIOS but with
device trees. No solution was specified by QCA and therefore a new one has
to be found for ath10k.
The device tree requires addition strings to define the variant name
wifi@a000000 {
status = "okay";
qcom,ath10k-calibration-variant = "RT-AC58U";
};
wifi@a800000 {
status = "okay";
qcom,ath10k-calibration-variant = "RT-AC58U";
};
This would create the boarddata identifiers for the board-2.bin search
* bus=ahb,bmi-chip-id=0,bmi-board-id=16,variant=RT-AC58U
* bus=ahb,bmi-chip-id=0,bmi-board-id=17,variant=RT-AC58U
