About that we have problems with patch author

yeah I saw that.
encountered a few problems with your repo but I managed to have a working build with drv and gmac.
Haven't looked into ECM yet.
It was very experimental but it worked... Extensive testing is required but I was a bit alone

So which qsdk version would you suggest to work on?
Also I am still not sure how to deal with nss-firmware files.

My suggestion at this point would be latest stable (what we target for ipq807x) and patch the qsdk to make it work with nss firmware 11.0 (only nss-core is needed to be patched)
That way we have more userbase.

@Ansuel you think this is related to the L2 freq issue?

Yep every kernel panic with undefined instruction/strange memory access that are not null or an error are thing related to the cpu going on a acid trip
I built it by including the qca-mcs package.
Can you tell me how to enable multicast snooping with nss?
Having the qca-mcs module loaded is not enough. Your need to also patch the IGMP/MLD mechanism you are using for multicast processing. I patched igmpproxy to trigger qca-mcs to accelerate multicast traffic for my ISP IPTV service.
It’s working somewhat and needs to be enhanced. As I need to use the router for actual use I abandoned the project tho and use normal Linux kernel multicast processing. It’s about 5% CPU saved, so my lazy bone took over and I abandoned the project. Haha.
If you are interested to continue where I left off, here’s the changes to igmpproxy:
HTH.

I changed the version of igmpproxy from 0.2.1 to 0.4 and built it with some modifications of your patch but openwrt failed to allow multicast traffic from iptv.
Did it work before?
My patch to igmpproxy basically configures the NSS drivers. It will not interfere with how igmpproxy works. Looks like you need to figure out how your IPTV service works with igmpproxy first.
igmpproxy works fine on non-patch builds.
I uncommented /etc/config/igmpproxy in a build with your patch and set it up as usual, and it didn't work.

Could it be because a lot of packages have been updated in the meantime, including openwrt and drivers?
Possible that there’s conflicts with packages. Do you see any errors logged?
Where can I see it? system log? kernel log?
Igmpproxy logs to syslog.
Before removing the comment, I was able to see the usual igmpproxy logs.
However, if I change the settings in /etc/config/igmpproxy to the following, I see the following log and no multicast traffic is processed.

Is your router configured with different vlan for the bridge?
The config list brport eth1.1 means the LAN bridge is configured to use eth1 on VLAN 1. You will need to adjust the config if you have changed the LAN bridge VLAN.
Edit: I would add that if you want to use multicast streams in your network, you should also configure the bridge to turn on IGMP snooping, or you may flood your switch ports with multicast traffic, which may also flood the WLAN interfaces.

I enabled and tested the options below.
uci set network.@device[0].igmp_snooping='1'
uci set network.@device[1].igmp_snooping='1'
It has VLAN named eth0.2 and eth1.1.
I usually use Luci to configure. I find using uci command too finicky as there are sometimes dependencies that I may missed out on.
In any case, I can’t really tell what’s the issue you’re facing without actually testing out the build you’re using. Most likely the qca-mcs driver you’re using have changed the netlink APIs from the one I used.

Today I have builded OpenWRT v23 firmware for Xiaomi R3D with built-in NSS driver.
Sources:
xiaomi_r3d.dts based on netgear_r7500v2.dts
Speed of WiFi 5G (80Mhz):
w/o NSS: 396 / 380 Mbps
with NSS: 680 / 363 Mbps
What else should be checked to improve performance?
How to check firmware stability?
How to check for memory leaks?
