The most simple mode is an active/passive failover. The active link is
used for sending and only when it fails(*) the other link is used.

(*) Failure is detected either by looking at the carrier status or by
sending arp probes to a configured peer.

agr(4) doesn't seem to support this. Packets are distributed over all
links, either round-robin or by selecting a link based on a hash of
the packet.
