A major flaw of the current xt_quota module is that quota in a specific rule gets reset every time there is a rule change in the same table. It makes the xt_quota module not very useful in a table in which iptables rules are changed at run time. This fix introduces a new counter that is visible to userspace as the remaining quota of the current rule. When userspace restores the rules in a table, it can restore the counter to the remaining quota instead of resetting it to the full quota.
