Linux support exists for the internal MIPS on some of those devices. My understanding is the switching hardware is licensed out to other chips that can be controlled externally (e.g. PCIe). Felix was the first chip to do so with full Linux support. When Seville came along, it utilized a lot of common code from Felix. Thus, Felix is a "chip" as well as a "library" - specifically the DSA implementation of Ocelot. At least in my mind. (Note: I haven't verified this timeline back to the early days of Felix...

Adding support for half of the ports is phase 2, and I need to sit down for another day or two to finish things up before that can happen. Hopefully very soon, as my calendar is finally freeing up...
