Yes, but - how do you connect e.g. such a cheap RealTek PC NIC to, let's say, a TNC2?

For some reasons (developing new data transfer methods, use of DSPs for Packet Radio) I would not prefer using an Ethernet chipset for both Ethernet and radio interface. What I had in mind was a modular solution like this:
+-------------+ +----------+ +--------------+
|PC Interface | |Protocol | |RadioInterface|
|(USB, Ether- |<>|Handler, |<>|(DSP, Modem, |
|net, serial) | |Buffers...| |whatever) |
+-------------+ +----------+ +--------------+

Yes, but usually, these are proprietary and complete solutions without great possibilities for changes and experiments.

For all? Could you or someone else please kindly point me to some information on how to do this for a z80-based TNC or a microcontroller application (preferrably, in a modular way as described above)?

Both true, but at the moment, I have no clue on how to connect some kind of TNC with an Ethernet interface.
