I am on Omnia with Turris OS 6.2.4. The kernel keeps sending this message. It wasn’t there before.
br-lan: received packet on lan0 with own address as source address (addr:xxxxx, vlan:0)
Of course it is a loop in the network, the MAC address is that Omnia itself. What could it be? Is something broken?
On port LAN1, i.e., lan0, I have the first of the nodes in my mesh network. It is a Linksys router used in bridge mode with four other identical nodes scattered around the house, always used as access points and connected to the main node via WiFi.
EDIT: af_packet: tpacket_rcv: packet too big, clamped from 33174 to 32638. macoff=82
Added to the earlier error was this other message.
As I have shown, the mesh network starts from the LAN0 port of Turris Omnia and propagates via the WiFi backbone network of the various Linksys nodes. So the first node is physically connected with an Ethernet cable to the only LAN port used on the Turris Omnia, and the other nodes connect via WiFi to the main node.
Plus I forgot that I re-enabled the router’s WiFi 6 network, which I use mainly for guests. I had tried disabling it, but the loop message keeps appearing.
I would suggest to switch the proto from 3G/UMTS to QMI as it can get you faster internet.
