Mauro Carvalho Chehab 8b4a503d65 docs: s390: convert docs to ReST and rename to *.rst
Convert all text files with s390 documentation to ReST format.

Tried to preserve as much as possible the original document
format. Still, some of the files required some work in order
for it to be visible on both plain text and after converted
to html.

The conversion is actually:
  - add blank lines and identation in order to identify paragraphs;
  - fix tables markups;
  - add some lists markups;
  - mark literal blocks;
  - adjust title markups.

At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.

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.
