Jayakumar, Thanks for pointing this out.
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.
