Subject: [patch net-next v3 0/8] expose flash update status to user

From: Jiri Pirko <jiri@...lanox.com>

When user is flashing device using devlink, he currenly does not see any
information about what is going on, percentages, etc.
Drivers, for example mlxsw and mlx5, have notion about the progress
and what is happening. This patchset exposes this progress
information to userspace.

Example output for existing flash command:
$ devlink dev flash pci/0000:01:00.0 file firmware.bin
Preparing to flash
Flashing 100%
Flashing done

See this console recording which shows flashing FW on a Mellanox
Spectrum device:
