[ovs-dev] [PATCH 1/4] ovn-sb: Southbound DB schema changes for DPDK/userspace tunneling support in OVN-Openstack integration.

[Sugesh Chandran]

From: sugeshch <sugesh.chandran at intel.com>

This patch contains changes for OVN southbound DB schema to expose Openvswitch/
hypervisor details. A new table named "PN_sysinfo" is created in the OVN
Southbound DB to store the information of each chassis.
