hashlimit_upto. Match if the rate is below or equal to amount/quantum. It is specified either as a number, with an optional time quantum suffix (the default is 3/hour), or as amountb/second (number of bytes per second). This parameter or hashlimit_above is required.

This patch adds a new feature to hashlimit that allows matching on the current packet/byte rate without rate limiting. This can be enabled with a new flag --hashlimit-rate-match. The match returns true if the current rate of packets is above/below the user specified value.
