1 IBM s390 QDIO Ethernet Driver 2 3 OSA and HiperSockets Bridge Port Support 4 5 Uevents 6 7 To generate the events the device must be assigned a role of either 8 a primary or a secondary Bridge Port. For more information, see 9 "z/VM Connectivity, SC24-6174". 10 11 When run on an OSA or HiperSockets Bridge Capable Port hardware, and the state 12 of some configured Bridge Port device on the channel changes, a udev 13 event with ACTION=CHANGE is emitted on behalf of the corresponding 14 ccwgroup device. The event has the following attributes: 15 16 BRIDGEPORT=statechange - indicates that the Bridge Port device changed 17 its state. 18 19 ROLE={primary|secondary|none} - the role assigned to the port. 20 21 STATE={active|standby|inactive} - the newly assumed state of the port. 22 23 When run on HiperSockets Bridge Capable Port hardware with host address 24 notifications enabled, a udev event with ACTION=CHANGE is emitted. 25 It is emitted on behalf of the corresponding ccwgroup device when a host 26 or a VLAN is registered or unregistered on the network served by the device. 27 The event has the following attributes: 28 29 BRIDGEDHOST={reset|register|deregister|abort} - host address 30 notifications are started afresh, a new host or VLAN is registered or 31 deregistered on the Bridge Port HiperSockets channel, or address 32 notifications are aborted. 33 34 VLAN=numeric-vlan-id - VLAN ID on which the event occurred. Not included 35 if no VLAN is involved in the event. 36 37 MAC=xx:xx:xx:xx:xx:xx - MAC address of the host that is being registered 38 or deregistered from the HiperSockets channel. Not reported if the 39 event reports the creation or destruction of a VLAN. 40 41 NTOK_BUSID=x.y.zzzz - device bus ID (CSSID, SSID and device number). 42 43 NTOK_IID=xx - device IID. 44 45 NTOK_CHPID=xx - device CHPID. 46 47 NTOK_CHID=xxxx - device channel ID. 48 49 Note that the NTOK_* attributes refer to devices other than the one 50 connected to the system on which the OS is running.
