IBM s390 QDIO Ethernet Driver OSA and 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 an OSA or 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. When run on HiperSockets Bridge Capable Port hardware with host address notifications enabled, a udev event with ACTION=CHANGE is emitted. It is emitted on behalf of the corresponding ccwgroup device when a host or a VLAN is registered or unregistered on the network served by the device. The event has the following attributes: BRIDGEDHOST={reset|register|deregister|abort} - host address notifications are started afresh, a new host or VLAN is registered or deregistered on the Bridge Port HiperSockets channel, or address notifications are aborted. VLAN=numeric-vlan-id - VLAN ID on which the event occurred. Not included if no VLAN is involved in the event. MAC=xx:xx:xx:xx:xx:xx - MAC address of the host that is being registered or deregistered from the HiperSockets channel. Not reported if the event reports the creation or destruction of a VLAN. NTOK_BUSID=x.y.zzzz - device bus ID (CSSID, SSID and device number). NTOK_IID=xx - device IID. NTOK_CHPID=xx - device CHPID. NTOK_CHID=xxxx - device channel ID. Note that the NTOK_* attributes refer to devices other than the one connected to the system on which the OS is running.
