Ah, that coincides with something I was wondering about. Isn't it
possible to have multiple multicast groups with generic netlink? If so,

There is one default mcast group per entity. Most users only need that
one.
If you need more, we go one of two ways:
a) Register for multiple IDs with the code as is. 
b) we could add a "reserve multicast group" interface in the kernel.

Thoughts?
