[Bug 2020461] Re: Backport nvme-stas to Ubuntu 22.04 (jammy)

[Benjamin Drung]

Verified libnvme 1.3-1~ubuntu22.10 on a ubuntu-22.10-desktop-amd64.iso
live system on my laptop. The Python snippet run as root prints
following model: "WD Blue SN570 2TB".

** Description changed:

  [ Impact ]
  
  NVMEoTCP is available on Dell’s primary storage platforms, Powerflex,
  PowerStore and PowerMax. Nvme-stas provides the CDC client functionality
  in Linux that allows for easy centralized deployment of NVMe-oF TCP
  storage.
  
  nvme-stas depends on libnvme which needs to be also backported.
  
  [ Test Plan ]
  
  python3-nvme from libnvme can be tested with that code:
  
  ```python
  from libnvme import nvme
  
  root = nvme.root()
  root.log_level('debug')
  print(f'root: {root}')
  
  host = nvme.host(root)
  print(f'host: {host}')
  
  subsystem = host.subsystems()
  print(f'subsystem: {subsystem}')
+ print(f'model: {subsystem.model}')
  ```
  
  Running this script as root on systems with NVMe inside should list
  them. On my system it prints `model: Samsung SSD 980 PRO 2TB`.
  
  nvme-stas comes with an autopkgtest (that succeeds on all architectures
  except s390x).
  
  [ Where problems could occur ]
  
  nvme-stas and libnvme are new packages in Ubuntu 23.04 "lunar". So
  backporting them has no influence on existing systems as long as they do
  not explicitly install them.
