Proxmox/PiMox installer for Ten64

An update has caused the untagged traffic to be discarded to the physical ethernet ports from VMs when using VirtIO network on a GuestVM.

Traffic on tagged VLANs have no issues.

Changing the network card emulation (checked the other three) resolves the issue but it comes with a serve performance hit.

Interesting, I’ll take a look at that sometime. My hunch is that it’s something to do with IP checksum offloads.

@mrcheap

Hence I suspect the switch, is there any updates or known bugs? Unless it’s in the kernel or mixture.

Possibly, there was another user that had issues with checksums.
Another device on their network was appending garbage to end of the Ethernet frames, and the DPAA2 hardware was including the garbage data in the checksum calculations (when the frame left the Ten64). It could be a similar problem

Suspect ten64 is corrupting packets

Hi forum, I’m wondering if I’ve made a config mistake in U-boot or somewhere else, or just have a slightly dodgy unit. I have some packet captures that show that my ten64 is altering UDP header checksums of some packets. I’m not sure what the exact circumstances for the corruption are, but I can reliably reproduce by using Minecraft for Windows connecting to a friend’s server - the ten64 seems to be putting 2 octets of random into the UDP header checksum of 60-byte (on the wire) Raknet ACKs. I…

I haven’t followed up that issue yet, but there are other ways it could be resolved without fixes upstream.

What’s the best way to control the fan? it feels like it’s at max, not sure if it’s summer here in Australia or no feedback controller.

You will need to compile the emc2301 module from here:
traversetech / ls1088firmware / traverse-sensors · GitLab
Make sure to add it to /etc/modules so it loads at boot.
The fan speed should go down immediately when it’s loaded, and it will automatically increase with CPU temperature

Any patch to enable the SFP+ activity lights for Debian Bookworm?

Try this:

modprobe ledtrig-netdev
cd /sys/class/leds/ten64\:green\:sfp1\:down
echo netdev > trigger
echo eth8 > device_name
echo 1 > rx
echo 1 > tx
echo 1 > link

You can do the same with ten64:green:sfp2:up and eth9

Unfortunately this has to be done each boot, due to the DPAA2 architecture having split MACs and PHYs, it isn’t possible to use the device tree bindings (hope to fix that someday).
