I agree, I had a look at the netback xenbus code and tried various
workarounds, but did not come up with anything that works better than
the current stuff. There are some thorny issues with regards to
unmapping/remapping the rx/tx rings and so on that must be dealt with
correctly, if this is to work.
For now, I will create a bug in bugzilla, and have a go at fixing it
later, unless someone beats me to it.
Regards,
Jacob
