This backport fixes high latency (>100ms) on the WiFi link when using a
QCA988x Wave 1 radio. The ath10k-ct driver is not affected by this bug

This reverts commit 9ad3b55654455258a9463384edb40077439d879f.
As reported by Sergey:
"I got some problem after upgrade kernel to 5.2 version (debian testing
linux-image-5.2.0-2-amd64). 5Ghz client stopped to see AP.
Some tests with 1metre distance between client-AP: 2.4Ghz -22dBm, for
5Ghz - 53dBm !, for longer distance (8m + walls) 2.4 - 61dBm, 5Ghz not
visible."
It was identified that rx signal level degradation was caused by
9ad3b5565445 ("rt2800: enable TX_PIN_CFG_LNA_PE_ bits per band").

Close cooperation with Lorenzo Bianconi resulted
in these patches which fix all remaining seen issues
when using dynack.
Fix link losses when:
- Late Ack's are not seen or not present
- switching from too low static coverage class to dynack on a live link
These are fixed by setting the Ack Timeout/Slottime to
the max possible value for the currently used channel width when
a new station has been discovered.
When traffic flows, dynack is able to adjust to optimal values
within a few packets received (typically < 1 second)
These changes have been thoroughly tested on ~60 offshore devices
all interconnected using mesh over IBSS and dynack enabled on all.
Distances between devices varied from <100m up to ~35km

Most of the txpower for the ath10k firmware is stored as twicepower (0.5 dB
steps). This isn't the case for max_antenna_gain - which is still expected
by the firmware as dB.
The firmware is converting it from dB to the internal (twicepower)
representation when it calculates the limits of a channel. This can be seen
in tpc_stats when configuring "12" as max_antenna_gain. Instead of the
expected 12 (6 dB), the tpc_stats shows 24 (12 dB).
Tested on QCA9888 and IPQ4019 with firmware 10.4-3.5.3-00057.

Issues a wmi command to firmware when multicast rate change is received with the

By default the firmware uses 1Mbps and 6Mbps rate for management packets

basic rates from the userspace, we need to send the management

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
