Log Message: 
Minor tweaks to support compilation of ether.cpp within MacOS. i.e. mostly
migrate the Ethernet driver to the MacOS side. This is enabled for
DIRECT_ADDRESSING cases. I didn't want to alter much of ether.cpp (as it
would have required to support that mode). Of course, in REAL_ADDRESSING
mode (the default) and for debugging purposes, the old driver is still
available.
