devlink: Add remote reload stats
Add remote reload stats to hold the history of actions performed due
devlink reload commands initiated by remote host. For example, in case
firmware activation with reset finished successfully but was initiated
by remote host.
The function devlink_remote_reload_actions_performed() is exported to
enable drivers update on remote reload actions performed as it was not
initiated by their own devlink instance.
Expose devlink remote reload stats to the user through devlink dev get
command.
Examples:
$ devlink dev show
pci/0000:82:00.0:
stats:
reload:
driver_reinit 2 fw_activate 1 fw_activate_no_reset 0
remote_reload:
driver_reinit 0 fw_activate 0 fw_activate_no_reset 0
pci/0000:82:00.1:
stats:
reload:
driver_reinit 1 fw_activate 0 fw_activate_no_reset 0
remote_reload:
driver_reinit 1 fw_activate 1 fw_activate_no_reset 0
$ devlink dev show -jp
