It is a little confusing, so I may well be misunderstanding but the
cover letter says:

$ devlink dev param set pci/0000:08:00.0 name enable_sfs_aux_devs \
value false cmode runtime

$ devlink port add pci/0000:08:00.0 flavour pcisf pfnum 0 sfnum 11

So both of these run on the same side, no?

What I meant is make the former part of the latter:

$ devlink port add pci/0000:08:00.0 flavour pcisf pfnum 0 sfnum 11 noprobe


Maybe worth clarifying - pci/0000:08:00.0 is the eswitch side and
auxiliary/mlx5_core.sf.1 is the... "customer" side, correct?
