Currently, dynack was only tested upstream using AP/STA mode.
Testing it on IBSS, showed that late-ack detection was broken.
This is caused due to dynack using Association Request/Response
frames for late-ack detection, which IBSS does not use.
Also allowing Authentication frames here solves this.
A second issue also got fixed, which was also seen AP/STA mode:
When a station was added, the estimated value would be exponentially averaged
using 0 as a starting point.
This means that on larger distances, the ack timeout was still not high
enough before synchronizing would run out of late-ack's for estimation.
Fix this by using the initial estimated value as a baseline
and only start averaging in the following estimation rounds.
Test setup:
- 2x identical devices: RB912UAG-5HPnD + 19dB sector
- IBSS
- 2x2 802.11an (ar9340), HT20, long GI
- RSSI's -70 / -71
- Real distance: 23910 meter
Results (60s iperf runs):
Fixed coverage class 54 (up to 24300m):
* 21.5 Mbits/sec
Dynack:
* 28.9 Mbits/sec

Registering a GPIO chip with the ath9k device as parent prevents unload,
because the gpiochip core increases the module use count.
Unfortunately, the only way to avoid this at the moment seems to be to
register the GPIO chip without a parent device

The most important is probably regression fix in handling platform
NVRAM. That bug stopped hardware from being properly calibrated breaking
e.g. 5 GHz for Netgear R8000.
Other than that it triggers memory dumps when experiencing firmware
problems which is important for debugging purposes.

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.

* FW has Smart Logging feature enabled by default for detecting failures
* and processing FATAL_CONDITION_EVENTID (36925 - 0x903D) back to host.
*
* Since ath10k doesn't implement the Smart Logging and FATAL CONDITION
* EVENT processing yet, suppressing the unknown event ID warning by moving
* this under ATH10K_DBG_WMI.
*
* Simulated the same issue by having associated STA powered off when
* ping flood was running from AP backbone. This triggerd STA KICKOUT
* in AP followed by FATAL CONDITION event 36925.

|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.
