Hi Angelo,

If this goes to a v6, I'd suggest adding a very brief statement that
#io-backend is present because it is possible (in theory anyway) to
use a separate controller for the control path than that used for the
datapath. 

So a one line summary of that long discussion from an earlier version!
 
Otherwise this LGTM.

Thanks,

Jonathan
