This might need further brainstorming. What are we actually interested
in?

The EEPROM has been read, we know what sort of SFP it is?

It happens to be a copper SFP, we know what MDIO over I2C protocol to
use, it responds, and the PHY device has been created? Does the SFP
layer actually know this? Are we actually adding a notification for
any PHY, not just an SFP PHY?
