This means that switchdev drivers won't ever have to treat a HOST_MDB
notification any differently than a PORT_MDB notification

No, they need to treat it very differently. 

Allow me to rephrase, switchdev drivers will ignore HOST_MDB
notifications because that does not resolve to something they can do
something about.

Hi Florian

Yes, they can. In fact, if they want to support IGMP snooping on the
bridge interface, they have to. How else do they know to forward
traffic to the host?

Fine, then add a boolean to the PORT_MDB notification that says ingress
or egress and voila, or am I missing something?

But since the semantics are so different, why not just have a
different messages?
