Yes. The model Linux uses is that the ports are individual interfaces to start with. We should keep to that model. > > MoreThanIP is now part of Synopsys.

Which is probably not available. You might be able to get some clues from the Freescale datasheets, if they have kept the address spaces separated. I don't see it as a strong requirement, given how old this IP is, and the limited interest in supporting it over the years, My guess is, nobody else uses it. Andrew
