Create special topic branch or ack so I'll prepare this branch. We are in -rc4 now and we (Mellanox) can't hold our submissions anymore. My mlx5_core probe patches [1] were too intrusive and they are ready to be merged, Parav's patches got positive review as well [2] and will be taken next. We delayed and have in our internal queues the patches for VDPA, eswitch and followup for mlx5_core probe rework, but trapped due to this AUX bus patch.
