status of carpdev?

[Tom Uffner]

what happened with the effort to port "ifconfig ... carpdev ..." to
FreeBSD?

the last messages mentioning it were posted a bit more than a year ago.
if i remember correctly, there was a patch for IPv4 only. it was considered
Beta test quality and a few people were using it. but since then i have not
seen it mentioned anywhere, and nothing has been committed.

what is the status, and is there a usable patch for 7.1?

thanks,

tom
