Considering the function of carp(4), I wonder why it is a kernel

In sum, I doubt that carp(4) provides enough utility to justify its
maintenance cost. If there are arguments to the contrary, I am
FWIW, the solaris equivalent (which is VRRP rather than CARP, for
whatever difference that really makes) does involve a kernel element.
I'm not certain if it is entirely in the kernel or if there's a
userspace element for protocol exchange, but the key point of having a
kernel device and interface is that you can attach config and
processes to a proper interface.
The Solaris implementation of VRRP does have a user space daemon that
the configuration. This is detailed in the design document for the
