+Realtek RTL8139C / RTL8139D / RTL8129 (?) PCI ethernet cards
+
+Second gen of Realtek network cards, driving away from the NE2000 design in '8029AS.
+'8139 is considerably popular, being the base of:
+- QEMU Virtual Machine;
+- Dreamcast BroadBand Adapter, thru a G2-to-PCI bridge codenamed GAPS (Sega ID 315-6170).
+https://github.com/sizious/dcload-ip/tree/master
+- And a gazillion of other OEM versions, a partial list at:
