Hello.

I am using DPDK-Pktgen (Pktgen version 2.77 using DPDK-1.7.1).
My NIC consists of two 10G ports.

Now, my question is : How are the port MBits/s Rx/Tx calculated?

Example: I am running the traffic generator with the following configuratio=
n:

*         400 Byte Packet Sizes

*         At Line Rate (i.e: 100%)

*         Unidirectional (Tx only)

The Pkts/s TX is 2985600. (Looks correct)
But the MBits/s Tx is set to 2006 (per port Tx).

How does DPDK-Pktgen calculate 2006 MBits/s Tx ?
Is this a bug?

Thanks in advance.

Best Regards,
Sami Assaad.
