[Bug 1601820] Re: ovs-vsctl is hanging

[Sothy]

Hello,

I did the following to configuraton. I am using three VMXNET3
interfaces. Two are binded to DPDK.

echo "NR_2M_PAGES=4096" >> /etc/dpdk/dpdk.conf

"DPDK_OPTS='--dpdk -c 0x3 -n 4 -m 1024' in /etc/default/openvswitch-
switch.

After that I am running to create ovs bridge. It worked. Then I try to create dpdk port. 
It says error "ovs-vsctl: Error detected while setting up dpdk0  see ovss-vswitchd log for more detaials "

Log says:

dpdk|ERR|Interface dpdk0 start error: operation not permitted
dpif_netdev|ERR| dpdk0, can not set multiq

Now I checked ovs-vsctl show, it show bridge and port. But there is
error.

Do you know wny? Thanks

Bug description:
  Hi,

  I am following the document to install OVS DPDK in Ubuntu 16.04

  https://insights.ubuntu.com/2016/05/05/the-new-simplicity-to-consume-
  dpdk/

  I installed.

  When I run 
  $sudo ovs-vsctl add-br br1 -- set bridge br1 datapath_type=netdev  , 

  it hangs, and it does not show any result.
  But when I opened another terminal, i run sudo ovs-vsctl shop.

  It shows bridge.
  When I do delete command, it hangs again.

  Do you know why?

  Thanks
