So an interface has administrative up and down states.
This is equivalent to `ifconfig eth0 up` and `ifconfig eth0 up`.
Modern interfaces also have carrier states - also up and down (or 
unknown if the interface does not support it).

Carrier up is the kernel saying "yup, there is something at the other 
end to talk to" and down is the kernel saying nothing is at the other 
end. Generally this means the cable is unplugged or you're not 
associated to an access point.
