Ignore or an issue? (trace output that appears to be docker/network related)

[KimoB]

I have been doing some forum searching, and I think I can ignore the following trace that pops up, but figured I would get another set of eyes on it.

 

I have a ConnectX-3 10G adapter setup in a LACP Bond.  (br0)  I initially added a vlan to this adapter for my web service, and was receiving these trace output's in my syslog.  After some googling it seemed to be related to docker and vlans (macvlan) so I decided (yesterday 12/22/22) to remove the web service vlan (80) from br0 and utilize a completely separate NIC attached to the vlan in question and setup br2.  I updated the Docker to have access to both br0 and br2.  I received what appears to be the same trace output this morning.  Is this something I should just ignore, or am I doing something wrong with my network configuration.

Macvlan call traces are usually the result of having dockers with a custom IP address and can end up crashing the server, upgrading to v6.10 or later and switching to ipvlan should fix it (Settings -> Docker Settings -> Docker custom network type -> ipvlan (advanced view must be enabled, top right)).

Thank you, I will give that a shot.
