Changed named of ECNTRL_THIN to ECNTRL_ONBOARD as the name isn't as 

applicable to the UTP version of the card.
Fixed selection of the internal/external transceiver to use the driver flags.

* onboard xceiver or not. Since the Clarkson drivers do a very

* there.
*
* Onboard transceiver selection:
* David Burren (davidb@melb.cpr.itg.telecom.com.au) May 1993
*
* Whereas Herb's original version of this driver kludged the transceiver
* selection into bit 7 of the unit number, it is now taken from the
* "flags" specified in the kernel config file.
* If bit 0 of the flags is set, the external transceiver is used.
* This has been tested with the Etherlink II and the Etherlink II TP
* (where the onboard transceiver is UTP).
