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:
https://admin.pci-ids.ucw.cz/read/PC/10ec/8139
