datapath: Add multicast tunnel support.
Something like this, on two separate vswitches, works to try it out:
route add -net 224.0.0.0 netmask 240.0.0.0 dev eth0
ovs-vsctl \
-- add-port br0 gre0 \
-- set interface gre0 type=gre options:remote_ip=224.0.0.1
Runtime tested on Linux 3.0, build tested on Linux 2.6.18, both i386.
