This module allows you to limit the packet per second (pps) rate on a per
destination IP or per destination port base.  As opposed to the `limit' match,
every destination ip / destination port has it's own limit.
.TP
.BI "--dstlimit " "avg"
Maximum average match rate (packets per second unless followed by /sec /minute /hour /day postfixes).
.TP
.BI "--dstlimit-mode " "mode"
The limiting hashmode.  Is the specified limit per
.B dstip, dstip-dstport
tuple, 
.B srcip-dstip
tuple, or per
.B srcipdstip-dstport
tuple.
.TP
.BI "--dstlimit-name " "name"
Name for /proc/net/ipt_dstlimit/* file entry
.TP
.BI "[" "--dstlimit-burst " "burst" "]"
Number of packets to match in a burst.  Default: 5
.TP
.BI "[" "--dstlimit-htable-size " "size" "]"
Number of buckets in the hashtable
.TP
.BI "[" "--dstlimit-htable-max " "max" "]"
Maximum number of entries in the hashtable
.TP
.BI "[" "--dstlimit-htable-gcinterval " "interval" "]"
Interval between garbage collection runs of the hashtable (in miliseconds).
Default is 1000 (1 second).
.TP
.BI "[" "--dstlimit-htable-expire " "time"
After which time are idle entries expired from hashtable (in miliseconds)?
Default is 10000 (10 seconds).
