Alexei Svitkine 1cef34125c Add Etherner drive source code and CodeWarrior project file, from:
https://web.archive.org/web/20131124123749/http://gwenole.beauchesne.free.fr/sheepshaver/files/SheepShaver-Ethernet.tar.bz2

The project can be used in CodeWarrior to build a binary blob that
can then be converted into EthernetDriverFull.i by hexconv.cpp.
