[dpdk-users] [pktgen]how to set pktgen tx rate and what does it mean

[Caianning]

Hi,
         I am using pktgen to send packet.
As the guide said, I set with cmd "set 0 rate 1" and got 1.19Mpps (pkt size 512B).
So my question: How to set it to get a specific packet rate, such as 1Mpps or 1Gbps?

Thanks.
