A table containing Ethernet type field entries that the
bridge will use to determine how to translate a Token Ring
(802.5 w/snap) packet to a CSMA/CD packet. If a received
Token Ring packet matches the Ethernet type field of an
enabled entry, the bridge will translate the Token Ring
packet to the frame format specified by
ctBridgeTransTrEnetSnapFormat. Else, it will translate the
packet to the opposite frame format.
