There was a review comment to select MDIO_DEVICE instead of PHYLIB. PHYLIB seems correct to me now that I'm looking at this again though. I came up empty looking for any other drivers that select MDIO_DEVICE. The objection was that DSA devices wouldn't need the PHYLIB API, so why force it to be built-in. NET_DSA selects PHYLINK which selects PHYLIB. I think we're ok going back to select PHYLIB if that was the only problem.
