Are the wifi lag/stall issues for R7800 fixed in 22.03.0-rc6? What about porting the fixes to 21.02.x? I lost track where we are, lots of discussion in this thread. Thanks for catching me up!

Yes, no more lag/stall issue for R7800 in 22.03.0-rc6.
Now give yourself the challenge to persuade @nbd to commit the same fixes to 21.02.x so the next 21.02.4 release will be golden again.
That would also be a great consolation prize for people running NSS image with PPPoE WAN. PPPoE/NSS is completely broken in 22.03 and Master (both on kernel 5.10 for R7800), so the only way to get NSS acceleration for PPPoE WAN is to revert back to 21.02 (kernel 5.4). But there you are with laggy WIFI issues. It's like being a little kitten trapped from both ends by 2 raccoon comrades-in-crime.

Thank you. Now, is the wifi performance better with these patches than it was in 21.02.1 or am I asking for too much? 
Yes, WIFI in 22.03.0-RC6 and current Master work as well as 21.02.1 and maybe even better.

Depends for who... I didn't notice any major differences in speed or access times - I'd even be inclined to say that speeds were better on 21.02 - especially on longer distances (on ipq4018).
One of the things we've been doing semi-successfully is adding more rigor to the tests, and retaining historical data, so we can better compare "improvements" going forward. Right now I see too much latency compared to the original (2016) ath9k effort, and don't have any good data on multi-station performance with the fixes we've landed to date. I think the
tx_queue_data2_burst=2.0
(and 3) AP changes need to be tested on more hw in particular, which will improve throughput from the AP in contended scenarios. Two patches starting at: Reducing multiplexing latencies still further in wifi - #10 by amteza have not made it into rc6, but are just scripts....
So my hope would be for all of us, to somehow, going forward, to not be "inclined" to think things have got worse or better, but to actually know.

We were not talking about lagging that could only be observed when running tests with tools like flent etc. The lagging problem in 21.02.2, 21.02.3, 22.03.0-RC5 (and earlier) was so severe that online meetings (WebEx, Zoom etc.) or online games appeared to be frozen for a few minutes (yes minutes!) when the lagging condition surfaced, to the point of having an unusable network. There were several different culprits that might trigger such condition, but one of the well-known culprits (as reported by many people, including me) was due to some WIFI client (e.g. phone etc.) leaving the home when these online activities were happening.

so far as I understand the walkaway bug was resolved by this: AQL and the ath10k is *lovely* - #780 by Lynx
we weren't so much talking about "lagging" but "halting" in that case.
The very first fix that cured that lagging/halting issue was this one:
https://git.openwrt.org/?p=openwrt/openwrt.git;a=commit;h=aab535d2bbc414aecde5770152e7da6690462b9a
"mac80211: add airtime fairness improvements
This reverts the airtime scheduler back from the virtual-time based schedulerto the deficit round robin scheduler implementation.
This reduces burstiness and improves fairness by improving interaction with AQL."

I am under the impression that was un-reverted with the true fix being the multicast fix. ?
Also, I am pedantic - "lag" to me means events measured in ms. "halting" means events measured in 100s of ms.

That fix was only for people using multicast (e.g. enabling uPnP) in their WIFI network. The horrible walkaway bug had nothing to do with multicast.
FYI, you can integrate all recent mac80211 patches from @nbd for 22.03/Master into 21.02 without any modification needed. You just need to build your own images.
@dtaht, see below ath10k-ct-smallbuffers driver tests on a TP-Link RE450v2 running v22.03-rc6, it took me awhile to compile a image that fitted in this small device.
WiFi connectivity as per below (same computer, same spots for computer and AP):
I performed a couple of RRUL_BE tests, and TBH I suspect they might be affected by the AP being CPU bounded. First one with tx_burst=2.0 and second one with tx_burst=3.0:
And after I proceeded to repeat the same download/upload test I ran with my mt76, see below:

I did a tcpdump capture of the 1-threaded test too, and it's available with the rest of the data followin the next link:

thx once again. I can live with this. Consistently low latency, even with lowere
The only thing keeping me awake at night are not knowing performance at distance with multiple stations.

At distance is in my list, however, multiple stations will be a bit trickier.
I took some time off. How's rc6, everyone?

It is working pretty fine here. After we got Felix's latest mt76 patch which solved the SSH issue, it's very stable.
I still owe you some farther from the AP flent tests, tho'.
