s390-tools/read_values.c
Nikolay Gueorguiev 37e471ec3d - Upgrade s390-tools to version 2.36 (jsc#PED-10303, jsc#PED-9591) 
* s390-tools: Define Rust MSRV as 1.75.0
  * Add new tools / libraries:
    - cpacfinfo: Tool to provide CPACF information
    - opticsmon: Tools to monitor optical modules for directly attached PCI based NICs
    - pvimg: Rust rewrite of genprotimg
  * Changes of existing tools:
    - chpstat: Add data bandwidth utilization column
    - chpstat: Add support for full CMCB
    - chpstat: Add support for new CMG types
    - dbginfo.sh: add overview commands and crypto update
    - hyptop: Support for structured output (json, json-seq, csv)
    - lszfcp: Add missing fallback marker for non-good fc_host port_state
    - lszfcp: Improve speed with many SCSI devices
    - pvattest: Add attestation policy check command
    - zipl: Add support of partitions of mirror md-devices
  * Bug Fixes:
    - lszcrypt: Fix wrong state showing up for removed AP queue within SE guest
    - lszfcp: Show device names line for zfcp_units without SCSI device
- Revendored vendor.tar.gz
