Is it possible to make the structure the driver points to opaque?
Once made, that would allow us to hack on the ifnet (or on its
successor - iflogical) more aggressively without breaking ABI/API.
Yes, that's the idea. Backward compatibility kinda conflicts
with making struct ifnet entirely abstract, but I don't see
that as a problem without solution. Only as a problem for
which an acceptable solution must be found.
For example: you can introduce a define that either old or
new drivers use to indicate whether they need full visibility
or whether an abstract type works. This then drives what is
defined/declared and how it's defined/declared.
The trouble is that core debugging is not doable via methods
i.e.
netstat -i | -I interface [-abdhntW] [-f address_family] [-M core]
[-N system]
becomes much more difficult to achieve.
