+ depends on NETFILTER_XTABLES
+ help
+ This option adds a `CLASSIFY' target, which enables the user to set
+ the priority of a packet. Some qdiscs can use this value for
+ classification, among these are:
+
+ atm, cbq, dsmark, pfifo_fast, htb, prio

+
+config NETFILTER_XT_TARGET_MARK
+ tristate '"MARK" target support'
+ depends on NETFILTER_XTABLES
+ help
+ This option adds a `MARK' target, which allows you to create rules
+ in the `mangle' table which alter the netfilter mark (nfmark) field
+ associated with the packet prior to routing. This can change
+ the routing method (see `Use netfilter MARK value as routing
+ key') and can also be used by other subsystems to change their
+ behavior.

+ depends on IP_NF_CONNTRACK || NF_CONNTRACK
+ help
+ This is a general conntrack match module, a superset of the state match.
+
+ It allows matching on additional conntrack information, which is
+ useful in complex configurations, such as NAT gateways with multiple
+ internet links or tunnels.
+
+ To compile it as a module, choose M here. If unsure, say N.
+
+config NETFILTER_XT_MATCH_DCCP
+ tristate '"DCCP" protocol match support'

+
+config NETFILTER_XT_MATCH_LIMIT
+ tristate '"limit" match support'
+ depends on NETFILTER_XTABLES

+ limit matching allows you to control the rate at which a rule can be
