fwcontrol failure with multiple firewire cards

[Sean Bruno]

I noted very strange behavior from all pieces of the firewire stack 
while testing this week when there are multiple firewire cards in a 
machine. 

Before I start submitting patches to fwcontrol/firewire for these 
issues, is there any signifcant backwards compatibility issues I need to 
be concerned about?

Should I come up with a way to make fwcontrol behave normally unless 
there is a new argument(eg -B to iterate over multiple cards)?  Or is ok 
to trash the old behavior in favor of one that understands multiple cards?
