Re: [RFC PATCH net-next 04/20] net: dsa: mv88e6xxx: factorize temperature access

It seems like this should be done with a flag, rather than the family.

However, don't spend too much time on this. I plan to rip it all out
and put it in the correct place, in the Marvell PHY driver. The
temperature sensor is in the PHY, and other Marvell PHYs also have
this temperature sensor.
