Hi,

Thank you for the outputs!

It looks like you have a loop on the NIC `eno3` which has received a packet with its own MAC address as the source address. I would check from the following in order to narrow down the issue:

- Check the network topology to ensure that there are no network loops.
- Verify that there are no IP conflicts in the network.
