OK, it was missing from the linux-msm so it got me confused but they just marked it not applicable as its
gonna go through a different tree then.
So it's sched to be applied ? Probably thermal-next?
(ot: anyway it's actually incredibile how good the net-next branch works compared to msm... they comment/review/approve patch in max 1-2 days... it's so good to push changes and gets an actual response...)

Yeah, netdev is just a matter of hours for a review.
MSM is couple of weeks to couple of months.
- Did a fresh update of
AX3600-5.10-restart - added all 'coolsnowwolf' ath11k patches to mac80211
- edited ath.mk and /tmp/.config-package.in to make the 512MB option appear and be selected in the wireless kernel packages menu
- edited the ax3600.dtsi to import the ipq8074-memory-512m.dtsi and added latter to target/linux/ipq807x/files/arch/arm64/boot/dts/qcom/
The resulting sysupgrade.bin was used to sysupgrade and produced again a working image on an AX3600. Have no AX6 to test it on.

Really appreciate the help! I didn't edit .config-package.in so the 512MB flag wasn't set at all. The 512MB profile does work on AX6.
How's the stability in AX6 so far? there are still memory leaks?
can you tell which offloading works (tx / rx wired, tx / rx wireless) and which isn't?
IoT radio suddenly broke when I was asleep, dmesg is full of this spam:
[144279.102362] ath10k_pci 0000:01:00.0: failed to send pdev bss chan info request: -108
[144285.102753] ath10k_pci 0000:01:00.0: failed to send pdev bss chan info request: -108

Memory leak is still there, but with more available memory to begin with there is now more breathing room. In my case before the 512MB patches OOM consistently occurred within 6 hours after boot (very light load, ~6 stations, AP only). After the patches it hasn't happened yet for 24 hours and counting.
Offloading seem to work in both directions on AX6.

I'm using robimarko's fork but I can't get fast transition working :
My ax3600 is used as dumb ap and is connected to other router also using openwrt.
my phone do transition from ax to other ap seemlessly, but when it try to go from the other ap to ax, the device get connected to wifi but then disconnect after 3 secs.
After that, if I try to reconnect to wifi, the phone hang in dhcp and don't get connected.
@avalentin did you do something special to get fast transition working ?

I experienced exactly the same with transition between coolsnowwolf build on two AX3600 in dumb AP mode, and even with 802.11r disabled. So probably it's not specific to robimarko's fork.
No, it's standard. Perhaps you miss this bit?

Please update your fork, we facing many packages error, example:
ERROR: please fix feeds/packages/utils/zstd/Makefile - see logs/feeds/packages/utils/zstd/dump.txt for details
What forks is everyone using atm? (maybe add this info to the wiki page?)
I just bought 2 of this because it looks it might be official supported in the near future 
Thanks! This script fixes roaming issue on coolsnowwolf build too. After running the latter for about 24h, I can say that the leak is there as well (512M profile patch is applied in these builds):
- The free memory looks solid with zero wireless clients
- Slowly leaks with 1-2 clients
Sadly, looks like no coolsnowwolf patches fix the leak 
I'm using a slightly older version of robimarkos tree with the 512MB patch and currently it looks like this:
root@OpenWrt:~# uptime
17:30:16 up 29 days, 23:02, load average: 0.00, 0.00, 0.00
So I guess it's rock solid.
It looks the coolsnow patches and the 512M patch make a clear difference:
19:55:15 up 2 days, 8:06, load average: 0.00, 0.00, 0.00
total used free shared buff/cache available
Mem: 417496 287380 52492 92 77624 67096
It seems to stabilise at around 77M.
Without, it workes less than 1 day.

Hm, maybe, I wasn't patient enough. I gave up after ~23h, seeing free mem gradually decreases, but it was far from 77M, more like 150M and dropping. OK, thanks for sharing: I'll give it a go again, this time till it OOM's or stabilizes
I noticed one strange thing. I have 2 AX3600: an originally global one, and a Chinese one. Both have bdata patched, and both flashed with identical coolsnowwolf OpenWrt builds. For some reason the global router has 92.8M of /overlay, while the CN one -- only 10.3M:

What could have caused this, and is there a way to get large /overlay on the second router too?
