[ovs-discuss] OVS Warning - vport

So it turns out that if I unload the openvswitch kernel modules the warning goes away.
I would this on the web page that explains it (I think):
"The *_get_stats functions call get_stats_via_vport(), which tries to get
information about ports attached to the kernel datapath. When a pure
userspace switch is used (eg, the OVS kernel module isn't loaded), ports
are not attached to a kernel datapath, so warnings get logged. This
commit handles that case and doesn't log a warning. However, if the
kernel datapath is loaded, ports attached to a userspace datapath will
still log a warning.
So without the kernel modules loaded I get the following error which is OK since I am using dpdk:
"2014-10-14T18:20:50.169Z|00011|dpif_netlink|ERR|Generic Netlink family 'ovs_datapath' does not exist. The Open vSwitch kernel module is probably not loaded."
PS – I still can not get OVS/DPDK working on ubuntu 14.04 – I am at wits end. Anyone willing to help me?

Could you provide more info on what you are trying to do?
Are you just trying to add a vlan interface?
Maybe provide the `ovs-vsctl show` output?

I am “trying" to get OVS/DPDK running on ubuntu 14.04.
I do not have it working yet – but I am getting the following message in ovs-vswitchd.log:
014-10-14T16:00:13.195Z|00011|netdev_linux|WARN|vlan4025: obtaining netdev stats via vport failed (No such device)
Anyone know what this is and what the fix may be?
