How does a frontend detect whether these options are supported by the

by a multicast list in xenstore?

A per-guest-vif list in xenstore would also have the advantage that it
would be easily accessible and usable by the network acceleration
modules, without having to republish the add/remove requests from
netback to any registered accelerators.

The best approach for accelerators would seem to depend somewhat on the hardware implementation. If the frontend plugin is able to deal with the request, there might be no need for the backend plugin to do anything.

Having netfront propagate the request to both the frontend plugin and the backend (which would relay it to the backend plugin) seems straightforward.

Parsing the xenstore entries in more than one place seems like an odd approach, particularly as there would ideally be coordination between the software driver and the accelerator.
