Hi Horatiu

What was your thinking between adding a new generic netlink interface,
and extending the current one?

I've not looked at your user space code yet, but i assume it has to
make use of both? It needs to create the bridge and add the
interfaces. And then it needs to control the MRP state.

Allan mentioned you might get around to implementing 802.1CB? Would
that be another generic netlink interface, or would you extend the MRP
interface?

Thanks
