This looks like the bug I introduced in r1.251 that should be
fixed in 1.252 and 1.253, I'm puzzled.

If you try 1.250 and 1.253 and tell me if you can reproduce the problem
that would be really helpful. In case you see something weird, Could
you include the routing table "netstat -rnf inet" in your report? If
you can also play with tcpdump on the various pseudo-interfaces and see
if something is wrong that would be great.

It's indeed no expected and generally shown for interfaces of type
IFT_ETHER. I don't understand how this can be shown for carp.
