network card failover on linux

Does Linux have anything like solaris "ip multipathing"?
I have 2 (eth0 10.50.4.1 and eth1 10.50.5.1)interface going to two
different subnet, if eth0 fails, it will failover to eth1. if eth0
connectivity is back up, eth1 should be inactive and fall back to
eth0.



Any help would be greatly appreciated
