  1. IBM s390 QDIO Ethernet Driver
  2. OSA and HiperSockets Bridge Port Support
  3. Uevents
  4. To generate the events the device must be assigned a role of either
  5. a primary or a secondary Bridge Port. For more information, see
  6. "z/VM Connectivity, SC24-6174".
  7. When run on an OSA or HiperSockets Bridge Capable Port hardware, and the state
  8. of some configured Bridge Port device on the channel changes, a udev
  9. event with ACTION=CHANGE is emitted on behalf of the corresponding
  10. ccwgroup device. The event has the following attributes:
  11. BRIDGEPORT=statechange - indicates that the Bridge Port device changed
  12. its state.
  13. ROLE={primary|secondary|none} - the role assigned to the port.
  14. STATE={active|standby|inactive} - the newly assumed state of the port.
  15. When run on HiperSockets Bridge Capable Port hardware with host address
  16. notifications enabled, a udev event with ACTION=CHANGE is emitted.
  17. It is emitted on behalf of the corresponding ccwgroup device when a host
  18. or a VLAN is registered or unregistered on the network served by the device.
  19. The event has the following attributes:
  20. BRIDGEDHOST={reset|register|deregister|abort} - host address
  21. notifications are started afresh, a new host or VLAN is registered or
  22. deregistered on the Bridge Port HiperSockets channel, or address
  23. notifications are aborted.
  24. VLAN=numeric-vlan-id - VLAN ID on which the event occurred. Not included
  25. if no VLAN is involved in the event.
  26. MAC=xx:xx:xx:xx:xx:xx - MAC address of the host that is being registered
  27. or deregistered from the HiperSockets channel. Not reported if the
  28. event reports the creation or destruction of a VLAN.
  29. NTOK_BUSID=x.y.zzzz - device bus ID (CSSID, SSID and device number).
  30. NTOK_IID=xx - device IID.
  31. NTOK_CHPID=xx - device CHPID.
  32. NTOK_CHID=xxxx - device channel ID.
  33. Note that the NTOK_* attributes refer to devices other than the one
  34. connected to the system on which the OS is running.
