Fixed In Version:	openvswitch-2.9.0-56.el7fdp	Doc Type:	Bug Fix
Doc Text:	Previously, an OVS-DPDK segfault would occur after an instance reboot or after initializing its networking interfaces. This was caused by a regression introduced by OVS 2.9 and occured with VMs having one or more OVS-DPDK ports and SR-IOV virtual functions. After this fix, OVS-DPDK will not longer segfault under these conditions.	Story Points:	---

Further information from Franck - this is a regression introduced by OVS 2.9 which causes a segfault when booting a VM with at least one OVS-DPDK port and one SRI-OV VF
