I have been maintaining and updating the patch referenced above at the github here:
https://github.com/mestery/ovs-vxlan However, no multicast support is implemented there either. I am currently working on getting the VXLAN patches upstream into OVS. Once that is complete, we can then implement multicast learning in userspace. I should note, however, that the VXLAN working group in the IETF is currently evaluating methods other than multicast to handle broadcast traffic across VXLAN. Checkout the NVO3 working group for more information on the plans there.
