I find windump to be more useful for this. Tethereal -d will give the
following:

c:\zdir>tethereal -D
\Device\Packet_NdisWanIp
\Device\Packet_{AC78607A-B557-41AC-A0F5-FA1465C34B2D}
\Device\Packet_{D9CEC815-AC3E-48A7-977A-B7E3BE2DFA68}

whereas windump will provide useful information about what the adapters is:

c:\zdir>windump -D
1.\Device\Packet_NdisWanIp (NdisWan Adapter)
2.\Device\Packet_{AC78607A-B557-41AC-A0F5-FA1465C34B2D} (Intel(R) PRO
Adapter)
3.\Device\Packet_{D9CEC815-AC3E-48A7-977A-B7E3BE2DFA68} (VPN Client Adapter)

Of course, this is probably only an issue if you end up changing adapters
from time to time.
