I'm concerned that we will be breaking user space compatibility with this
change, as there should be a corresponding fcoemon/fipvlan change along with
this, and existing utilities will not work.  Also the way we start fcoe will
be completely different and the user may need to do the scripting changes,
if any.

I agree with Bhanu on these concerns, even though I hope everyone's
using fcoeadm/fcoemon/fipvlan.  I think there needs to be more of a
transition plan than requiring everyone moving to a new kernel to
update the user-space tools at the same time.  Removing the module
parameters with the last patch might be rushed, they should probably
remain for a few kernel cycles with a warning.  When the tools are
updated for the new interface, they should probably maintain fallback
support for the module parameters for a while as well.
