I expect that there are a few such differences between OXM and the current
implementation. My plan is to get code in place to the point where we can
start sending messages. Code that as much as possible uses the existing
implementation. Then to focus on the corner cases.
As you may have noticed, part of my plan is to get patches out as they
are done rather than waiting to have a complete working implementation.
Primarily this is for review; so I can get feedback along the way; and so
you don't get overloaded by a huge patchset later on.
I do expect to have to go back and fix things up as the implementation
