Hi all,
I'm using Ovs-2.8.0 + DPDK-17.05-rc1 with two netdev using mlx5 driver,
like this:
$ sudo /usr/local/share/openvswitch/scripts/dpdk_nic_bind --status

When I start ovs-vswitchd, and add port onto br0, I got errors like this:
libibverbs: Warning: no userspace device-specific driver found for
> /sys/class/infiniband_verbs/uverbs2
and git errors in ovs-vswitchd.log like this:

Hi,
I would say you don't have the correct Linux drivers, nor libraries to
make it work with DPDK.
Did you installed Mellanox OFED? If not take a look at section 19.5.
Prerequisites of the NIC documentation [1].
