Whatever it is, adding a variable to an ethernet device and then
manipulating it in both the phylib and the ethernet code is desastrous.
It must be clear everytime who owns a variable. Doing a
eth_current->carrier = CARRIER_UNKNOW;
in the ethernet code, and then:
edev->carrier = dev->link;
in the phy code is a recipe for spaghetti code.
