updated!) should hardware offloading be enabled for tests or not?
htop is showing no apparent difference to CPU usage whilst running a Google speedtest, regardles of whether Wireless Ethernet Dispatch is returning Y or N via cat /sys/module/mt7915e/parameters/wed_enable.
I am currently running SNAPSHOT r20037-c29b13cfa0 but had the same issue with previous snapshots.bridger and irqbalance and have SW & HW offloading enabled. I am using the schedutil govenor.
I'm using a single 5GHz WiFi client with an Intel AX200 card and a DHCP connection to my head router at present.
Am I doing something wrong? Can anyone shed any light onto this please?

That seems to be somewhat old, already known bug.
The bug FS#3561 is also related to MTK hardware offloading, but it's a different issue which has already been resolved, we never saw that on Linux 5.10. Doesn't mean that it's unrelated, but it's definitely a different place in the code where things go wrong.

the device is bananapi r64, image was built using code from r64-emmc … branch of https://github.com/graphine27/openwrt
(this branch is mainly modifing image build for emmc setup, codes related to hw offload is not modified.)
this branch is after b59d5c8f0eebb6d15d7cefe487c17fad0ee4a524
the kernel oops (as panic) randomly if hw flow offload is enabled.
panic log here, note that virtual address "ffffff883e35ffa0" do not change amoung builds of kernel, even all the same in both 5.4.86 and 5.4.85

bug
My router works fine until it randomly goes into recovery mode and this happens … at least once every day. When it does go into recovery mode i then have to use ethernet, ssh and delete the pstore log, then reboot which temporarily fixes it.
**Version:** latest **Device:** belkin rt3200
I've tried re-flashing openwrt several times, and also updated to the latest version using the luci tool, but still have this issue. I've pasted cat /sys/fs/pstore* below:

Unfortunately, wed is not functioning anymore since the PPPoE fix (2 months ago?). I reported the issue to the author, but the situation did not change, furthermore those patches went upstream in the kernel. Maybe Felix or Daniel could update us with their plans to hopefully reintroduce the wed acceleration.

Thank you very much @Gix . Ultimately, I'd like to make this my head router and as I have a gigabit internet connection, throttled by the ISP to around 600Mbps but needing PPPoE to communicate with an ONT, I'd like all the hardware acceleration I can get.
I hope WED can be made functional again.

Anyone know is Users needed to test 2 Gbps WAN/LAN NAT Routing on ramips MT7621 devices - #4 by arinc9 would work on this?
edit: nvm I see phy-mode = "2500base-x"; in the DTS. probably no point in doing this.
my router is working great on 22.03.0-rc5
Great to see this device see full release soon.

wikidevi for mr7622 says
Ethernet: 5-port 10/100Mbps; ESW RGMII x1, (H)SGMII x 1
aggregating RGMII and HSGMII sounds like a bad idea.
Speaking of which, I see no reference to a second MII in dts.
yes I too the wifi has not disconnected for the moment I cross my finger,

Is anyone else experiencing throughput slowdowns when on a 5ghz DFS channel (like 100) with the latest mt76? I get about 500-600 megabits/s with iperf3, then after a long period of time, when I run it again I only get about 100-150 megabits/s.
There seems to be some DFS changes which have affected another chipset (https://github.com/openwrt/mt76/issues/676 ) but just wondering if it's just me.
Nah, aggregate the switch ports to take advantage of that internal 2.5Gbit/s link.
Though it'll probably be slow and have no purpose. (Don't see any offload handlers for bonding in the mt7530 DSA driver, but I may be wrong).
Fun experiment nonetheless. I wonder if you could actually use that to route 2Gb/s one way by aggregating both pairs of two ports.

Trying to install wireguard but getting version incompatibility message. I thought I had the latest 22.03. Do I need to update or have I got to learn to compile my own?

You need to update before you can install packages. You can use the attended upgrade under system in luci.

Yes, but even on regular channels including just ethernet.
Started sometime around build 199xx.
That said I've had nothing but stability as far as the 5GHz cutting out- hasn't happened at all since.

I have a question about upgrading the U boot on this router to the 0422 version. There is a note about this in the rc5 announcement. Previously I have updated the boot loader with the releases Daniel G posts but the file name is different.
https://downloads.openwrt.org/releases/22.03.0-rc5/targets/mediatek/mt7622/openwrt-22.03.0-rc5-mediatek-mt7622-linksys_e8450-ubi-bl31-uboot.fip
My questions are if I flash this file will it act like the installer file I've used before? So flash this then access the router at http://192.168.1.1 over Ethernet then flash a sys upgrade .itb (or .bin) file and restore settings. Or is it more complicated (i.e. no LuCI and need to know the command lines)?
I also see the image build servers are now referencing the official firmware selector page which creates a .bin file so that's different, too. Will flashing a customized sys upgrade .bin file work the same as a .itb from the old build pages?
Thanks in advance to someone in the know.

What note do you mean?
You can upgrade with: Belkin RT3200/Linksys E8450 WiFi AX discussion - #1318 by daniel
Beware it might soft brick the router if something goes wrong, needing serial or JTAG to fix.
If you mean
uboot-mvebu: update to version v2022.04
That's for Marvell platforms.

Thank you for replying.
So right now I am running uboot 0122 and updating snapshots with my added packages using the sysimage build pages or auc. I have been able to update uboot versions in the past by downloading the installer images from here - https://github.com/dangowrt/owrt-ubi-installer/releases
Those uboot installer files have LuCI so I can flash erasing my settings then access the web ui to flash a sysupgrade then restore settings.
As you and the post mention, flashing the base files looks to be an entirely different and risky procedure and not sure how the bl31.uboot.fip file needs to be updated - https://firmware-selector.openwrt.org/?version=22.03.0-rc5&target=mediatek%2Fmt7622&id=linksys_e8450-ubi Does this file behave differently than the installer files from Daniel's site?
if there is a 0422 uboot image that works like the release files Daniel made, then I would use it as I have done in the past.
The second part was being sure that flashing a .bin sysupgrade file with added packages will behave the same way as the .itb files I had been building at https://chef.libremesh.org/ . This page no longer lets you create images, so I am now using the openwrt firmware page https://firmware-selector.openwrt.org/ which creates .bin files with a different file size and displays different output text after it builds the image.
I want to be sure that things will update correctly since I haven't updated using a .bin image generated from that page yet.
Because this device has been in snapshot since I began using openwrt, I haven't used the official pages for anything and want to be sure that at release time I don't end up with a dead router.

Why not just use auc?
Are you sure you got a bin while on the UBI version? Think it should be itb.
