1 IBM s390 QDIO Ethernet Driver
3 OSA and HiperSockets Bridge Port Support
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".
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:
16 BRIDGEPORT=statechange - indicates that the Bridge Port device changed
19 ROLE={primary|secondary|none} - the role assigned to the port.
21 STATE={active|standby|inactive} - the newly assumed state of the port.
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:
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.
34 VLAN=numeric-vlan-id - VLAN ID on which the event occurred. Not included
35 if no VLAN is involved in the event.
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.
41 NTOK_BUSID=x.y.zzzz - device bus ID (CSSID, SSID and device number).
43 NTOK_IID=xx - device IID.
45 NTOK_CHPID=xx - device CHPID.
47 NTOK_CHID=xxxx - device channel ID.
49 Note that the NTOK_* attributes refer to devices other than the one
50 connected to the system on which the OS is running.
