- Updated the cputype script to recognize the new IBM z14
  processor (bsc#1049843).
- Re-instated the new versions of ctc_configure, dasd_configure,
  qeth_configure, zfcp_disk_configure, zfcp_host_configure.

# ctc_configure
#
# Configures a CTC device
# Copyright (c) 2017 SUSE LINUX GmbH, Nuernberg, Germany.
#
# Configures a CTC device by calling the IBM-provided chzdev command.
# Whereas this script used to validate the parameters provided to it,
# we now rely on chzdev to do that instead. The script is intended only
# as a "translation layer" to provide backward compatability for older
# scripts and tools that invoke it.
#
# Usage:
# ctc_configure <read channel> <write channel> <online> [<protocol>]
#
# read/write channel = x.y.ssss where
# x is always 0 until IBM creates something that uses that number
# y is the logical channel subsystem (lcss) number. Most often this is 0, but it could be non-zero
# ssss is the four digit subchannel address of the device, in hexidecimal, with leading zeros.
# x is always 0 until IBM creates something that
# uses that number
# y is the logical channel subsystem (lcss) number.
# Most often this is 0, but it could be non-zero
# ssss is the four digit subchannel address of the
# device, in hexidecimal, with leading zeros.
# online = 0 to take the device offline
# 1 to bring the device online
# protocol = 0 Compatibility with peers other than OS/390®, or z/OS, for example, a z/VM TCP service machine. This is the default.
# protocol = 0 Compatibility with peers other than OS/390®, or z/OS, for

# 4 For MPC connections to VTAM on traditional mainframe operating systems.

#
# qeth_configure
#
# Configures a qeth device
# Copyright (c) 2017 SUSE LINUX GmbH, Nuernberg, Germany.
#
# Configures a qeth device by calling the IBM-provided chzdev command.
# Whereas this script used to validate the parameters provided to it,
# we now rely on chzdev to do that instead. The script is intended only
# as a "translation layer" to provide backward compatability for older
# scripts and tools that invoke it.
#
# Usage:
# qeth_configure [-i] [-l] [-f -t <CARDTYPE> ] [-o "Values"] -n <portno> -p <portname> <read chan> <write chan> <data chan> <online>
#
# -i Configure IP takeover
# -l Configure Layer2 support
# -f force creation of udev rules, do not check values in /sys
# -t Valid cardtypes are: qeth, hsi, osn
# -f Override safety checks
# -t Valid cardtypes are: qeth, hsi - Deprecated
# -o General QETH options, separated by spaces
# -n QETH port number to use, 0 or 1. Only needed for real, not virtual devices.
# -p QETH Portname to use. Only needed if sharing a real OSA with z/OS.
# -n QETH port number to use, 0 or 1. Only needed for real, not virtual
# devices.
# -p QETH Portname to use - Deprecated. OSAs no longer need a port name.
# read/write/data chan = x.y.ssss where
# x is always 0 until IBM creates something that uses that number
# y is the logical channel subsystem (lcss) number. Most often this is 0, but it could be non-zero
# ssss is the four digit subchannel address of the device, in hexidecimal, with leading zeros.
# x is always 0 until IBM creates something that
# uses that number
# y is the logical channel subsystem (lcss)
# number. Most often this is 0, but it could
# be non-zero
# ssss is the four digit subchannel address of
# the device, in hexidecimal, with leading
# zeros.
# online = 0 to take the device offline
# 1 to bring the device online
#
# Return values:
# 1 sysfs not mounted
# 2 Invalid status for <online>
# 3 No device found for read channel
# 4 No device found for write channel
# 5 No device found for data channel
# 6 Invalid device type
# 7 Could not load module
# 8 CCW devices grouped different devices
# 9 Could not group devices
# 10 Could not set device online
# 11 Could not set device offline
# Return codes are determined by the chzdev command.
