Hi team,
My name is Sam and I am a Software Engineer.
Currently, we are trying to improve the performance of proprietary in-house
tools by using DPDK but we are not sure whether DPDK has support for TCP
stack.
If yes, could you please point me to the link of apis alone. I will take it
from there

OK, then shortly speaking, DPDK will NOT care about padding.
NIC will care about padding while send and recv with NIC.
kernel will care about while send and recv with vhostuser port.
Is that right?

Hi all,
As we know, ethernet frame must longer then 64B.
So if I create rte_mbuf and fill it with just 60B data, will
rte_eth_tx_burst add padding data, let the frame longer then 64B
If it does, where is the code?
Hi all,
I'm running OVS-DPDK on server:
OVS-2.3.0
DPDK-2.2.0
kernel-centos7.3.1611
And sometimes, VF port could NOT send specific flow packet.
So how to deal with this problem and where to report this issue?
Thank you~
I have test dpdk testpmd, it is OK in the same enviroment.
Why ovs-dpdk could not work? I think that must be some bug in ovs?

Hi all,
I'm using OVS2.8.0+DPDK17.05+Intel_82599_IXGBE for test, the vf driver is
ixgbevf-4.0.3.
I use sriov follow like this:

Then test l3fwd-vf demo, it is OK.
Then test OVS2.8.0, and assign pf for ovs like this:
ovs-vsctl add-port br_t dpdk-
Oh, it should be user1,8 in dpdk-17.05

Hi all,
I'm using OVS2.3.0-DPDK2.2 and ixgbevf-4.0.3 under CentOS-7-3.10.0-514
I bond 2 vf port into bond1.
Now some IP can't ping through bond1, and bond1 also can't ping these IP.
but at the same time, some IP ping bond1 OK.
Is there someone got same problem as I said?

I found a bug about ixgbevf kernel module in centos-3.10.0-229.20.1.el7.
And this bug is also in 3.10.0-514.10.2.el7.
How to produce this bug: use SRIOV first, then add lots of network traffic
on vf port, and then ifdow/ifup vf port, after many times, this bug happens.
