Hi,
this is a follow-up to my post from 3 weeks ago [1]. I'm starting a new
thread here since I now got a completely new test setup for improved
reproducibility.
Background for anyone that didn't catch my last post:
I'm investigating a performance regression in my packet generator [2]

Hi Nissim
Are you using PF pass-through or VF pass-through?
For PF pass-through, you might have already gotten the fix.
For VF pass-through, there is a bug fix which is needed for supporting jumbo
frame and multiple mbuf. http://www.dpdk.org/dev/patchwork/patch/4641/

Hi,
I am using PF pass-through and it doesn't work even with 2000 bytes of server
response page size.
Looks like the first segment of each session is not received.
When i am changing the server response size to 1000 bytes, all works as
expected.
I am working with dpdk 1.8 version.
Any idea wh

Ok will stub out the pci_config stuff for BSD.
But I don't have time or resources to do real BSD support.
Also, the whole bnx2x driver loads firmware and that probably has dependencies
that are different on BSD

Hi all,
after a small amount of offline discussion with Marc Sune, here is an
alternative proposal for a higher-level interface - aka pktdev - to allow a
common Rx/Tx API across device types handling mbufs [for now, ethdev, ring
and KNI]. The key code is in the first patch fo the set - the second
This is a trivial example showing code which is using ethdevs and rings
in a neutral manner, with the same piece of pipeline code passing mbufs
along a chain without ever having to query its source or destination
type.

I probably shouldn't stick my nose into this, but I can't help myself.
An experienced programmer will tend to ignore the documentation for
a routine named "blahblah_memcmp" and just assume it functions like
memcmp. Whether or not there's currently a use case in DPDK is
completely irrelevant becaus
