=================================
These cycles are consumed by retries and inefficient API calls enqueuing and
dequeuing smaller bursts than specified by the cmdline parameter. This results
in a larger cycle-count measurement and should not be interpreted as an offload
-cost measurement.
+cost measurement. Using "pmd-cyclecount" mode will give a better idea of
+actual costs of hardware acceleration.
On hardware devices the throughput measurement is not necessarily the maximum
possible for the device, e.g. it may be necessary to use multiple cores to keep

+ Set the distribution of packet sizes.
- Set the number of segments per packet.
+ A list of weights must be passed, containing the same number of items than buffer-sz,
+ so each item in this list will be the weight of the packet size on the same position
+ in the buffer-sz parameter (a list have to be passed in that parameter).
+
+ Example:
+
+ To test a distribution of 20% packets of 64 bytes, 40% packets of 100 bytes and 40% packets
+ of 256 bytes, the command line would be: ``--buffer-sz 64,100,256 --imix 20,40,40``.
+ Note that the weights do not have to be percentages, so using ``--imix 1,2,2`` would result
+ in the same distribution
+
+* ``--segment-sz <n>``
+
+ Set the size of the segment to use, for Scatter Gather List testing.
+ By default, it is set to the size of the maximum buffer size, including the digest size,
+ so a single segment is created.
