Subject: [PATCH net-next 00/11] mlxsw: extend line card model by devices and info

Jiri says:

This patchset is extending the line card model by three items:
1) line card devices
2) line card info
3) line card device info

First three patches are introducing the necessary changes in devlink
core.

Then, all three extensions are implemented in mlxsw alongside with
selftest.

Examples:
$ devlink lc show pci/0000:01:00.0 lc 8
pci/0000:01:00.0:
  lc 8 state active type 16x100G
    supported_types:
      16x100G
    devices:
      device 0
      device 1
      device 2
      device 3
$ devlink lc info pci/0000:01:00.0 lc 8
pci/0000:01:00.0:
  lc 8
    versions:
        fixed:
          hw.revision 0
        running:
          ini.version 4
    devices:
      device 0
        versions:
            running:
              fw 19.2010.1310
      device 1
        versions:
            running:
              fw 19.2010.1310
      device 2
        versions:
            running:
              fw 19.2010.1310
      device 3
        versions:
            running:
              fw 19.2010.1310

Note that device FW flashing is going to be implemented in the follow-up
patchset.
