+Subject: [PATCH] Port data plane status extension implementation
+
+Implements the port data plane status extension. Third parties
+can report via Neutron API issues in the underlying data plane
+affecting connectivity from/to Neutron ports.
+
+Supported statuses:
+ - None: no status being reported; default value
+ - ACTIVE: all is up and running
+ - DOWN: no traffic can flow from/to the Neutron port
+
+Setting attribute available to admin or any user with specific role
+(default role: data_plane_integrator).
+
+ML2 extension driver loaded on request via configuration:
+
+ [ml2]
+ extension_drivers = data_plane_status
+
+Related-Bug: #1598081
+Related-Bug: #1575146
+
+DocImpact: users can get status of the underlying port data plane;
+attribute writable by admin users and users granted the
+'data-plane-integrator' role.
+APIImpact: port now has data_plane_status attr, set on port update
+
+Implements: blueprint port-data-plane-status
+
+Depends-On: I04eef902b3310f799b1ce7ea44ed7cf77c74da04
