OK, at least part of the _____ was "Learn how MAC addresses are  

By using BF as the most significant byte, my MAC started with  
10111111, *with an LSB of 1*.  This makes it a multicast address.   
Doh.  So my determination that I didn't have networking was correct,  
only more correct was that I didn't have unicast networking  
(obviously what's useful here) and I shot myself in the foot to boot.

I've switched to 02 (00000010) as my first byte which both makes it a  
unicast address and follows the proper form for a locally-assigned MAC.

I still don't have DHCP working yet, but I can now at least see the  
network, and am on to other errors.
