└─> "limit" match support

In linux kernel since version 2.6.16 (release Date: 2006-03-19)  

limit matching allows you to control the rate at which a rule can be
matched: mainly useful in combination with the LOG target ("LOG
target support", below) and to avoid some Denial of Service attacks.

To compile it as a module, choose M here. If unsure, say N.
