I would guess that it would be better to run it on the carp interfaces,
but in a switched environment there should not be too much effective
difference - the physical interface should not be seeing traffic destined
for the virtual arp address of a carp interface when it is in slave mode.

On the other hand, running multiple instances of softflowd shouldn't
waste too many cycles.
