On a guest VM, I can be receive multicast packets on SR-IOV VF ports. Is
there anyway to enable the VF ports to receive multicast packets ?
However, I could receive multicast packets on non-SR-IOV virtual interface
ports via bridge or OVS on the guest VM after I call this routine
ixgbe_dev_allmult
of ip, I do not see it describes about adding more than
one VLAN IDs to the same VF port.
Can I use this ?
ip link set eth6 vf0 vlan 3,13
Thanks

Any one know what commands to use on the KVM host to add multiple VLAN IDs
to a SR-IOV port ?
I could only add one VLAN ID using
ip link set ethN vf NUM vlan VLANID
Also do I have to call any routine on the DPDK side to add those VIDs ?

expected ? How can I configure the host to not add tag since
traffic from the VM is already tagged. Otherwise it becomes double tagged.
Thanks

I could not pass tagged traffic through the l2fwd program running inside a
CentOS VM. The l2fwd program reported sending out all the packets received
from one port to the other port. But the outside Spirent tester could not
receive a packet at all. I am wondering maybe the tagged packets are

Anyone knows how to turn off TSO in DPDK+SR-IOV in KVM guest VM ? I want

I found that it used to have l2fwd-vf in DPDK 1.2.3 release (
http://www.dpdk.org/browse/dpdk/tree/examples/l2fwd-vf/main.c?h=1.2.3)
But in the next release 1.3.1, that directory is gone. Does that mean it is
merged to some other tool ? Which tool can I use to send/receive L2 traffic

I am trying to make SR-IOV + DPDK l2fwd to work together. I can only send
one directional traffic, not bi-directional.
The traffic is one-directionally looped back by l2fwd using DPDK l2fwd as
illustrated below

it have to map from the IO port address in the VM to the physical
port address in the host for EVERY access ? If that's the case,some
improvement can be done if we use similar way as the vmxnet3 model ?

Running one directional traffic from Spirent traffic generator to l2fwd

is a CentOS 32bit (CentOS 6.2, Linux 2.6.32-220.el6.i686). There are two
