Basically devlink adds a new eswitch port (the SF port) and loading the drivers and the interfaces is done via the auxbus subsystem only after the SF is spawned by FW. > Question number two - is this supposed to be ready to be applied to > net-next? It seems there is a conflict. > This series requires other mlx5 and auxbus infrastructure dependencies that was already submitted by leon 2-3 weeks ago and pending Greg's review, once finalized it will be merged into mlx5-next, then I will ask you to pull mlx5-next and only after, you can apply this series cleanly to net-next, sorry for the mess but we had to move forward and show how auxdev subsystem is being actually used.

Thanks, Saeed.
