I've tried adding a iptable rule
sudo iptables -A COUNTER -m limit -n --limit 1024/sec --limit-burst 1024 -j ACCEPT
But when i try to see the rules using iptables-save -c or iptables -nvxL the output is
-A COUNTER -m limit --limit 1111/sec --limit-burst 1024 -j ACCEPT
I'm unable to understand how the 1024/s is getting translated to 1111/sec
I've tried with other limits also and few of the limits are getting changed.Can anyone explain what is happening
Similarly if i try with 900/sec it is getting translated to 909/sec

I'm guessing it has something to do withCREDITS_PER_JIFFY, and particularly the scaling that is done inuser2credits, innet/netfilter/xt_limit.c.
