[dpdk-users] Minimal dpdk configuration for 2 hosts

[dawid_jurek]

Hello,
I wonder what is the minimal configuration (in sense on number of NIC ports) to run basic dpdk examples like
basicfwd, rxtx_callbacks or forwarding by testpmd for 2 hosts connected directly by Ethernet.
Is it possible to perform one directional transmission for some kind of sender-reciever scenario (2 hosts, every host with one port)?
It seems that for every kind of transmission between 2 machines I need at least 4 ports
(because every port may take care of TX or RX but not both of them at the same time).
Is it correct?
Regards,
Dawid
