To decrement the IP TTL, the existing TTL can't be less than two. The
field is not bit-maskable, though, so "ip.ttl < 2" will not work.

Decrements the IPv4 or IPv6 TTL. If this would make the TTL zero
or negative, then processing of the packet halts; no further
actions are processed. (To properly handle such cases, a

+ higher-priority flow should match on
