Deprecating the old interfaces instead of immediately removing them 
sounds like a good idea to me.

I hope everyone is using fcoeadm/fcoemon/fipvlan too. We do still carry 
the 'fcc.sh' script in fcoe-utils.git/contrib/. I don't use it, but I 
know others do. I did not update 'fcc.sh' with my user space change.

I'll post the fcoemon changes to devel@open-fcoe.org. I think I have a 
bunch of cleanup patches that the change depends on, so the series will 
probably be half cleanup and half feature.
