Do you have a term that broadly covers in-host/in-kernel, sometimes virtualized or “software-defined”, non-copper/fiber/wireless networking?

Looking back at a few years of Jails/Zones/bhyve networking with @crest while he’s working on if_pair, it occurred to me that just about everything in this host context was or is still burdened by limitations from physical media.

I threw some notes on the Jails/Zones doc to start the conversation.
