OVS supports wildcarding the multicast bit of the Ethernet destination
address independently of the rest of the bits.

We're asking for community help with OF1.1 and OF1.2 support (see
http://openvswitch.org/development/openflow-1-x-plan/).  That will
add, among other features, wildcarding of individual bits of the
Ethernet source and destination addresses.
