qsdk 10 using ct drivers / firmware.
This is an access point that is dedicated to wifi duties. Connected via a LAN port (no DHCP and no other tasks) to the main router.
I asked stats from an OEM firmware as on our nss firmware doesn't implement WiFi API at all

Actually WiFi is not detected as local traffic so it would be offloaded in theory

@ACwifidude @KONG - There are a number of changes needed against HEAD now, some of which I am not sure I properly merged. Would either of you guys mind rebasing and pushing?
I’m on a nice long summer vacation. I’ve been casually watching the commits and will update sometime next week when I get back. 
Good number of kernel updates and .dts updates that can trip up the merging process.

Just updated my nss tree, after setting up a 21.02 tree without nss. The 21.02 will replace my 19.07 tree.
19.07 build might get one last update before 21.02 will take over along with nss builds that are based on master.

Thank you, built fine.
@KONG @ACwifidude - Looks like something in HEAD or the 5.4.139 kernel broke the build again. I dug in a bit but it's over my head. Do either of you guys have some time to check it out?
Complete build log with error.
You'll need to patch master with the two commits in PR#4221 to get my proposed rebase of kernel 5.4.139.

it's very easy to fix, refer to the commits on how to fix this. Minimal changes required 
Sorry, which commits? Plus, you're assuming I understand the errors
The .138 patch seems benign and should build.
The .139 patch may interfere with this recent commit: https://git.openwrt.org/?p=openwrt/openwrt.git;a=commitdiff;h=774b386a928339ef1169f5b121fce2ccd3aa5e96
I’d double check these recent changes against your patch and see if there is a conflict.

I'll have to let one of you guys take this... it's beyond me to figure out what's wrong and fix it.
EDIT: Just grepping for some key words here not knowing what the actual code does.
My 5.4.139 patch shows

0002-kernel-bump-5.4-to-5.4.139.patch: static void smsc95xx_init_mac_address(struct usbnet *dev)

maddr = (uint8_t *)of_get_mac_address(np);
I'm not sure what to change nor if I'm remotely on the right track.
Added a patch that uses new of_get_mac_address api:

Confirmed functional NSS with 5.4.139. Thanks!
Building @KONG 's kernel5.4-nss-qsdk10.0 branch against HEAD recently throws an error:

When you build with 1 job it seems the problem is an option in the config (kernel?) is not refreshed. I'm wondering how to fix this. Note that if I build without rebasing in kong's kernel5.4-nss-qsdk10.0 branch, I do not experience this.

I rebuilt at this commit from a couple days ago “kernel: bump 5.4 to 5.4.140”
Don’t see any obvious commits that would cause major issues since that time.
Is it complaining about your config file in the log?
I successfully compiled HEAD+5.4.142 by first building the build bot R7800 config, then make clean and rebasing against kong's branch and my own nss config. Let me try this again a bit later today going right for the NSS code + 5.4.142.

Hi, need help, can i use the branch openwrt-21.02-ipq806x-nss-qsdk11 on quarkysg's repo? is this stable? if not please suggest me which branch should i try.
Also, do i need to select the nss modules under kernel? if yes please let know which ones from the below to be selected. im no system programmer, pls help
I would suggest you try @ACwifidude repo. Mine does not include the NSS firmware. If you manage to get hold of the 11.2 NSS firmware, feel free to use my repo. My R7800 is running it now, with 63 days uptime.
Otherwise pls try @ACwifidude repo.
