As a whole, the following packet lengths (CRC included) must be tested to
check all packet memory configurations:
-#. packet length < mbuf data buffer size
+1) packet length < mbuf data buffer size
-#. packet length = mbuf data buffer size
+2) packet length = mbuf data buffer size
-#. packet length = mbuf data buffer size + 1

in a single buffer.

The -n command is used to select the number of memory channels. It should match
the number of memory channels on that setup.
-Setting the size of the mbuf data buffer to 1024 makes 1025-bytes input packets
