Another thought that occurred to me over the weekend: FPIN is fibre-
channel only. What if someone has a mix of FC and other transports?
Would it make sense to use FPIN for FC paths and "traditional" marginal
path detection for others? If yes, we'd need to change the logic and
we'd probably have to add a 4th mode ("fpin-mixed" or whatever).
