Anyone have an idea what this packet means, or at least where in the
kernel/app sources to look? It was taken on a Linux 2.6 host using “any”
capture. For the vast majority of the packets in the trace it display the
ethertype as the Protocol for the SLL header. I had a hard time tracking down
where in the kernel sources it would generate a 0 ethertype, and they payload
doesn’t look like a netlink packet.
