This provides the required vxlan bridging function but poses a
scalability problem with using a separate vxlan netdev for each vni.  

if I remember correctly this issue was the main reason David Ahern
put netdev on diet. Sounds like no more fun at netconf ;)
 

oh, it still needs a diet ...  

 Even if the netdev went on diet, a netdev per vni for vxlan deployments is just too much overhead.

But the intent was VNI == VLAN tag and there are cases where you need per VNI rules.
Having them all smashed into one netdev seems like a step in the wrong direction.
