But the other infrastructure may have same issues (netfilter, etc).
Just seems like it would be either to have multiple network devices
so that upper layers could disambiguate easier.

That's quite a heavyweight solution to what is purely
an addressing issue, don't you think?

We can just revert all of that netdev_ops stuff if you
think per-netdev cost doesn't matter :-)

I am just concerned that is a fundamental change (like MQ) was and
it will take a couple of releases to shake out all the inter-relationships.
When an architectural change is made, would like to see more analysis done.
Netdev-ops was more of a refactoring than a change to what protocols
and qdisc/filters/... see.
