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