If I want to establish communication between two N3000 cards or more cards in a host server, how should I do. For instance, I want to forward a packet or a stream from Card A to Card B directly or using PCIe.
Anyone knows how to do or some suggestions or valuable reference？
You will need to have some application to do that, and we do not provide these tools. There are some tools online that you might want to explore such as iperf and packetEth_cli. We do not provide support for these tools, but you might want to check it out and see if it works for you.
