I do not know of the specific patch at this moment, but I use carp
devices on every one of my FreeBSD firewalls. I have used CARP as the
basis for clusters of web / db / mail / NFS etc. servers combined with
devd and some other unique concepts. I have had no problems with CARP at
all for over 2 years now on both the 6-STABLE and 7-CURRENT / 7-STABLE
branches. 

Tested firewall fail over with my configs using CARP when we started
pulling Ethernet plugs resulted in, at most, negligible packet loss
while pinging. From the application layer perspective, no sessions
experienced any interruption while fail over testing all systems I run
CARP on.
