* @ count : Indicates number of rules to be added or deleted .
* @ rule_info : Array of flow rules to be added or deleted .
*
* For VIRTCHNL2_OP_FLOW_RULE_ADD , rule_info contains list of rules to be
* added . If rule_id is 0 xFFFFFFFF , then the rule is programmed and not cached .
*
* For VIRTCHNL2_OP_FLOW_RULE_DEL , there are two possibilities . The structure
* can contain either array of rule_ids or array of match keys to be deleted .
* When match keys are used the corresponding rule_ids must be 0 xFFFFFFFF .
*
* status member of each rule indicates the result . Maximum of 6 rules can be
* added or deleted using this method . Driver has to retry in case of any
* failure of ADD or DEL opcode . CP doesn ' t retry in case of failure .
