We have information about what MII they can handle, however we don't store anything about whether they are currently connected to an SFP module or not. As phy_port aims at listing the front-facing ports, let's store an "vacant" bit to know whether or not a MII port is currently vacant (i.e. there's no module in the SFP cage), or not (i.e. there's an SFP module).
vacant == False actually means a bit more than there is a module in the cage. It also means that, so far, we have not had any errors trying to use the module. If there is an error, we might have a module physically in the cage, but vacant == True. We should be careful with the wording, both in the commit message, and here:
