on my computer it does not work, i disconnected the wire from
the ethernet port and the ifconfig is the same, i think it
tells if the interface is up in the kernel, not if the inteface
has carrier from switch/hub. This is from ifconfig man page:

       up     This flag causes the interface to be activated.  It
              is implicitly specified if an address  is  assigned
              to the interface.
