When the TC tool add a flower filter the VCAP rule corresponding to this filter will be disabled (kept in memory) until a TC matchall filter creates a link from chain 0 to the chain (lookup) where the flower filter was added. When the flower filter is enabled it will be written to the appropriate VCAP lookup and become active in HW. Likewise the flower filter will be disabled if there is no link from chain 0 to the chain of the filter (lookup), and when that happens the corresponding VCAP rule will be read from the VCAP instance and stored in memory until it is deleted or enabled again.
