There is no source that's why its a Martian. A Martian packet is one for
which the host does not have a route back to the source IP address
(i.e. it apparently dropped in from Mars). These days most hosts have a
default route, meaning that there would be no such thing as a Martian
packet. Your kernel is merely logging this fact.
