should looking at an interface with 'ifconfig' trigger a change ?

I do not have phsyical access to the machine, so I did this using
a sutdown of the interface on the sitch - but yes, it works! This fixes
the progem with lagg as well - it now fails over to the other interface

Such a simple patch - if this has no ill effects then I will deploy it
on al our servers,m and hope for it to be committed soon. All new HP
servers appear to come with bce interfaces, so this is an importnat fix
for us, and probably a lot of other people too. Thanks.
