+HiperSockets Bridge Port Support
+
+Uevents
+
+To generate the events the device must be assigned a role of either
+a primary or a secondary Bridge Port. For more information, see
+"z/VM Connectivity, SC24-6174".
+
+When run on HiperSockets Bridge Capable Port hardware, and the state
+of some configured Bridge Port device on the channel changes, a udev
+event with ACTION=CHANGE is emitted on behalf of the corresponding
+ccwgroup device. The event has the following attributes:
+
+BRIDGEPORT=statechange -  indicates that the Bridge Port device changed
+  its state.
+
+ROLE={primary|secondary|none} - the role assigned to the port.
+
+STATE={active|standby|inactive} - the newly assumed state of the port.
