For probe-time config module param is probably our only option.
I'd obviously prefer to have a devlink-level knob for this, instead
of a mlx5 specific one. Can we come up with some format that'd apply
more broadly? devlink=[$bfd:]flag1 ? so devlink=[$bdf:]switchdev-mode ?

BTW looks like issues Sashiko/Claude finds are slightly different,
let me send them out.
