Hi Thomas and Roman,
It seems to happen if I have set -mavx in C
To be a bit more specific, this is what I had to do to fix it for clang 3.6 SVN

I am not sure if there is a better way of handling this situation. I'd love to

Hello,
Based on the wonderful assistance from Vladimir and Stephen and a close friend
of mine that is a hypervisor developer who helped me reverse engineer and
rewrite rte_lpm_lookupx4, I have got a known-working version of rte_lpm4 with

I have not used XL710 or i40e.

Actually I have no idea why this happens.
If your switch configuration is correct, your program should work just like
Wireshark does.
I wander whether your program uses RSS.
In my opinion, program bug is the most probable reason.

You said that your configuration works well with Wireshark.
So I don't think that this is the problem.

Hi,
I am trying to understand DPDK and i
modified dpdk-2.0.0/examples/rxtx_callbacks so that i get a message
whenever i RX and TX a frame.
I added a printf in add_timestamps() and calc_latency() to know whenever i
am able to RX and TX a packet along with the # of pkts that i get --
print nb_pkts.

And whenever I check t
