tra —
Fujitsu MB86950 based Tiara Ethernet cards driver
The tra driver supports Tiara MCA bus Ethernet adapters
  and clones, based on the Fujitsu MB86950 Ethernet controller. Supported boards
  include:
  - Tiara LANCard/E Ethernet Adapter
-  
- Standard MicroSystems 3016/MC Ethernet
-  
 
The tra driver appeared in NetBSD
  4.0.
The tra driver has been written by Dave
  Barnes ⟨djb_pizza@ieee.org⟩.
Multicast is not supported. There is no hardware support for multicast, and the
  driver does not implement a software-only solution.
