Hi Folks
I am trying to use ovs (master) with dpdk (2.0.0). I had followed the guide
https://github.com/openvswitch/ovs/blob/master/INSTALL.DPDK.md and built
everything successfully
I then created a ovs bridge and added a SR-IOV VF as a dpdk interface. The
bridge gets created as expected, however vswitchd segfaults on getting the
first packet
Is this a known issue?
Regards
Prem
