I think i have tx offloading disabled on both ends of this adapter. (Both on windows and on linux.)

 

I haven't seen any actual instructions on how to disable it, and I'm running everything through NetworkManager.

❯ sudo route

❯ sudo nmcli con show 8277ed12-04f7-4c82-bfeb-de24ec2df104 |grep tx
ethtool.feature-tx:                     off

 

Thanks for the assistance.

Armbian is a community driven open source project. Do you like to contribute your code?

19 hours ago, gprovost said:

@Zageron Yeah please formulate a clear question.

 

To check if tx offloading is on or off

 


ethtool -k eth1 | grep tx-checksum

 

Currently TX checksum offload for all network interfaces on rockchip64 family is disable in Armbian by default.

 

Yay 24 hour delay is over. This is regarding the degraded performance of the 2.5gbe on 5.8. I am unsure if my iperf results are aligning with what others are seeing. Given that tx offload is definitely off, I assume so.

 

Formulated context and question:

I have just put my helios64 together. I am seeing degraded performance of the 2.5gbe interface as warned.

The notes I saw everywhere were "disable tx checksum offload".

How do I check if tx offloading is on or off?

 


I tested with ethtool, and yes it is off.

❯ sudo ethtool -k eth1 | grep tx-checksum
tx-checksumming: off
        tx-checksum-ipv4: off
        tx-checksum-ip-generic: off [fixed]
        tx-checksum-ipv6: off
        tx-checksum-fcoe-crc: off [fixed]
        tx-checksum-sctp: off [fixed]

 

I assume I have nothing else to do but wait for patches to improve the degraded performance at this point?

 

Thanks for your patience and your answers!

The other end looks like this:

I managed to get performance up to 2.21 gbps by switching mtu to 9000 on both sides.

However, resetting tx and rx offloading to default on on both ends results in the exact same performance. (2.21gbps)

 

fyi mtu was set on linux with

sudo nmcli con modify <interfaceuuid> ethernet.mtu 9000

 

Edited by Zageron
Added instructoins for making mtu changes permenant.

Ok interesting.

 

On my side I don't see any iperf difference increasing MTU beside seeing more retries.

 

Here my perf with default MTU 1500.

Just for the sake of clarification because iperf can be confusing. By default iperf client test upload speed.

 

iperf -c <helios64-ip>  = test RX speed of Helios64

 

iperd -c <helios64-ip> -R = test TX speed of Helios64

Okay I understand a little more now. Receiving on helios is very slow, sending is slightly faster.

Note that rx is on.

❯ sudo ethtool -k eth1 | grep rx-checksum
rx-checksumming: on

(same with windows, IP Offloading is set to rx only)

I see! Yes, modifying settings on the windows machine has improved both. However, I am still seeing consistent lock-up / crashing of the interface.

Is there anything I can grab for you for details?
