+This target marks packes so that the kernel will log every rule which match
+the packets as those traverse the tables, chains, rules. (The ipt_LOG or
+ip6t_LOG module
+is required for the logging.) The packets are logged with the string prefix:
+"TRACE: tablename:chainname:type:rulenum " where type can be "rule" for
+plain rule, "return" for implicit rule at the end of a user defined chain
+and "policy" for the policy of the built in chains.

+It can only be used in the
+.BR raw
+table.
