little bit more cumbersome to code, but safer.
The last time that I looked the DPDK rte_dump_stack() is using vfprintf(),
which isn't safe in a signal handler. However, it's been several DPDK
releases since I peeked at the details.

Hey Robert,
Thanks for the insight. I work with Jay on the code he's asking about; we
only have one mbuf pool that we use for all packets. Mostly, this is for
the reasons that you describe, as well as for the sake of simplicity. As
it happens, the stack trace we're seeing makes it look as
=1.

some recent discussion here, I also tried changing the
TX RS threshold from 0 to 32, 16, and 1. None of these strategies proved
effective.
Like I said at the top, I'm a little at a loss at this point. If you were
dealing with this set of symptoms, how would you proceed?
Thanks in advance.

Keith speaks truth. If I were going to do what you're describing, I would
do the following:
1. Start with the l2fwd example application.
2. Remove the part where it modifies the ethernet MAC address of received
packets.
3. Add a call in to clone mbufs via rte_pktmbuf_clone() and send the cloned
accomplish.

I want to emphasize this point. It's unsurprising that Jay and I agree,
since we work together. But I can say with
effectiveness at load spreading
with typical traffic data. Not all 16 bit values will do this.

Specifically, our calls to rte_eth_tx_burst() get return values that
indicate that no packets could be sent.
Is there an additional step that we have to do on link down/up operations,
perhaps to tell the NIC to flush its descriptor ring?
Thanks in advance for your help.

point me to
some example code that demonstrates the steps needed to configure RSS?
We're using Niantic NICs, so I assume that this is pretty standard stuff,
but having an example to study is a real leg up.
Again, thanks for all of the information.

egmented into 2K chunks.
Any chance we could get an improvement to the documentation about this
parameter? It seems as though the opaque pointer isn't a pointer and
probably shouldn't be opaque.
Hope this helps the next person who comes across this behavior.

Thanks Roger,
We saw similar issues with regard to kcompat.h. Can I ask if you've done
anything beyond the example applications under 14.04?

-of-the-envelop estimate) of how badly such a configuration would hurt
performance? For sake of argument, assume that virtually all of the memory
being used is in pre-allocated mempools (e.g lots of rte_mempool_create(),
very little rte_malloc().
Thanks in advance for your help.
