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 <code>ip.ttl < 2</code>.)
+ higher-priority flow should match on
+ <code>ip.ttl == {0, 1};</code>.)
