carpdev

[Alexander Vyrlanovich]

I mean ifconfig carp0 carpdev iface
to attach carp pseudo-device to iface.

The goals is to have physical iface and attached carp device
configured in different IP subnets like OpenBSD can do.
(for example if ISP assign /30 subnet to me, where only two IPs
can be located)
