I think all are pretty much covered if you let some controler (I prefer
user space) ADD/DEL/GET/Event on the fdb
TRILL really is outside the scope of this; from an encap/decap it
probably needs to be YAND (Yet another netdev) and from a control side
of things you need to just provide the above netlink ops(ADD, etC) on
the fdb and let the controller worry about things (Actually you _may_
need to have learning done outside of the kernel for TRILL)

Agreed.
