Danny, can you specify multiple --vdev parameters?
"--vdev=eth_packet0,iface=eth0 --vdev=eth_packet1,iface=eth1"

Does it support specifying multiple NIC interfaces using command line option
like "--vdev=eth_packet0,iface=..."? Say "iface=eth0,eth1,eth2...", tried but
it doesn't work.

Tried on 3.12, both of them are undefined. Anyway, will comment them out and
see what performance it could achieve.

Hello.
I've noticed that DPDK 1.7.0 version has been released a few days ago.
The DPDK vSwitch package, however, seems supporting old version, 1.6.x,
only.
Could the DPDK vSwitch be compiled by the latest DPDK?
Or Do I need to use 1.6.x version of DPDK?
Thanks in advance.
Best regards
Hi,
I tried another workaround and works fine:
It similar to other kcompat function, add __kc_ prefix to function
definition
and #define skb_set_hash(a,b,c) __kc_skb_set_hash(a,b,c).
Thanks,

Ah, yes...sorry, I misunderstood what you wanted to do. The syntax
below is what I would expect to use.

I'm not sure that would make any sense -- the AF_PACKET sockets are
mapped to specific interfaces.
What are you trying to do with a syntax like that?

Hi Sujith,
It makes sens, using VFIO makes a far cleaner implementation.
You worked on the performance, could you share some measurements ? Did you
introduce vectorization functions as Intel did a while ago? There are allways
tradeoffs between pps and latency, do you include documentation to

Not sure what the issue might be, PACKET_FANOUT_FLAG_ROLLOVER is
defined in include/uapi/linux/if_packet.h in the v3.12 tree.

Hi Matt,
I normal only compile the core DPDK code and then compile my Pktgen traffic
generator application
(git clone https://github.com/Pktgen/Pktgen-DPDK) which uses a fair amount of
functions from DPDK.
Thanks

I was playing with vhost example to measure VM to VM throughput. With
default SW mode I saw 9Gbps. While trying HW mode, traffic does not

Hi Bruce:
Thanks for your suggestion.
I have tried to use testpmd to test 16 ports today.
The result is so Interested. It can work, although some ports get low
performance (only get 80%).
Besides, I also do another test in l2fwd.
I tried to use 82580 * 16 ports in the same platform with l2fwd

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?

Hi Hobywan,
Thanks for the email !
We?ve been working on performance benchmarking. Also, we felt that it would be
better to push the driver after Anatoly?s patch (vfio-pci) got in so that we
could make the necessary modification before submission.
Now that 1.7.0 is out, we are hopeful of

The FreeBSD nic_uio driver was missing the #defines to include the device ids
for devices using the i40e driver. This change adds in the missing defines.

The one problem I had with 14.04 was the kcompat.h file. It looks like a hash
routine has changed its arguments. I edited the kcompat.h file and was about to
change the code to allow DPDK to build. It is not affix but it worked for me.
