(The Sample Application guide introduction referring the merge) The L2 Forwarding sample application is a simple example of packet processing using Intel(r) Data Plane Development Kit (Intel(r) DPDK) which also takes advantage of Single Root I/O Virtualization (SR-IOV) features in a virtualized environment. Note: Please note that previously a separate L2 Forwarding in Virtualized Environments sample application was used, however, in later Intel(r) DPDK versions these sample applications have been merged Thanks, M Jay -----Original Message----- From: dev [mailto:dev-bounces@dpdk.org] On Behalf Of James Yu Sent: Friday, January 10, 2014 8:32 PM To: dev@dpdk.org Subject: [dpdk-dev] send/receive L2 packets from SR-IOV ports using l2fwd-vf I found that it used to have l2fwd-vf in DPDK 1.2.3 release ( http://www.dpdk.org/browse/dpdk/tree/examples/l2fwd-vf/main.c?h=1.2.3) But in the next release 1.3.1, that directory is gone.

I was using l2fwd in DPDK 1.3.1r2 but could not consistently passing one directional traffic. I have the following question when using l2fwd: 1. Can I kill the l2fwd using ctrl-c on linux command and restart it again ? Would it be gracefully shutting it down ? 2. If I reboot the VM, would that recover the SR-IOV ? 3. Do I have to issue any commands on the guest or host, or reboot the host after I restart l2fwd to make the SR-IOV work again ? Sometime I could pass traffic one directional from Spirent. The traffic was sent to port 1 and received on port 2. But the other direction sending traffic to port 2, however, did not receive traffic on port 1. I have posted the description and setup on the other email thread with this title "[dpdk-dev] one directional traffic from SR-IOV port using l2fwd". If you know how to make bi-directional traffic work, please reply to that email thread. Thanks.
