Stream type defines ISO OSI network layer used + for simulation of multiple streams. + Data type: str + Supported values: + "L2" - iteration of destination MAC address + "L3" - iteration of destination IP address + "L4" - iteration of destination port + of selected transport protocol + Default value: "L4". + 'pre_installed_flows' + - Pre-installed flows is an extension of the multistream" + feature.

Supported + values are: + 'srcmac' - Specifies source MAC address filled by traffic generator. + NOTE: It can be modified by vsperf in some scenarios. + Data type: str + Default value: "00:00:00:00:00:00". + 'dstmac' - Specifies destination MAC address filled by traffic generator. + NOTE: It can be modified by vsperf in some scenarios. + Data type: str + Default value: "00:00:00:00:00:00". + 'framesize' - Specifies default frame size.
