- 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.
