*** Keywords ***
+| Get Max Rate And Jumbo
+| | [Documentation]
+| | ... | Argument framesize can be either integer in case of a single packet
+| | ... | in stream, or IMIX string defining mix of packets.
+| | ... | For jumbo frames detection, the maximal packet size is relevant.
+| | ... | For maximal transmit rate, the average packet size is relevant.
+| | ... | In both cases, encapsulation overhead (if any) has effect.
+| | ... | The maximal rate is computed from line limit bandwidth,
+| | ... | but NICs also have an independent limit in packet rate.
+| | ... | For some NICs, the limit is not reachable (bps limit is stricter),
