CARP is 'special' in that it needs to add its own MAC addresses to your 
interface, needs a bit of special cooperation between the IP layer and 
the MAC layer, and it's more than likely that this doesn't work with 
if_bridge.

Like Max says, this is an unusual configuration.... what are you trying 
to do?
