The patches add feature that DPDK apps can attach and detach physical NIC ports and virtual device ports at runtime. Also I have patches for testpmd to attach and detach ports dynamically. For example, after patching, we can type following commands. testpmd> port attach p 0000:02:00.0 testpmd> port attach v eth_pcap0,iface=eth0 testpmd> port detach p <detaching port_id> testpmd> port detach v <detaching port_id> (These are just RFC.) Now I am collecting up patches to submit to dpdk.org. So I can send RFC patches soon. Hopefully next week. Thanks, Tetsuya
