Subject: [patch net-next 0/7] 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.

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

Jiri Pirko (7):
  mlxsw: Move firmware flash implementation to devlink
  mlx5: Move firmware flash implementation to devlink
  mlxfw: Propagate error messages through extack
  devlink: allow driver to update progress of flash update
  mlxfw: Introduce status_notify op and call it to notify about the
    status
  mlxsw: Implement flash update status notifications
  netdevsim: implement fake flash updating with notifications
