Don't trap flag (i.e. IB_FLOW_ATTR_FLAGS_DONT_TRAP) indicates that QP will receive traffic, but will not steal it. When a packet matches a flow steering rule that was created with the don't trap flag, the QPs assigned to this rule will get this packet, but matching will continue to other equal/lower priority rules. This will let other QPs assigned to those rules to get the packet too. If both don't trap rule and other rules have the same priority and match the same packet, the behavior is undefined. The don't trap flag can't be set with default rule types (i.e. IB_FLOW_ATTR_ALL_DEFAULT, IB_FLOW_ATTR_MC_DEFAULT) as default rules don't have rules after them and don't trap has no meaning here.
