it seems no-one ever replied, can you give us more details about the
traffic and network configuration that reproduces the panic?
what does the output of 'ip address' show? vconfig?
it seems as if GRO is pushing a packet into the stack to be forwarded
that gso is mad about due to checksum != CHECKSUM_PARTIAL, esp when
stacked upon macvlan and/or vlan:

All the data continuously generated in your IT infrastructure
contains a definitive record of customers, application performance,
security threats, fraudulent activity, and more. Splunk takes this
data and makes sense of it. IT sense. And common sense.
