A clue....

- Subject: [ECOS] A clue....
There is some debugging output below. But what I figured out is that my
receive code isn't receiving *ALL* packets, it is only receiving
*BROADCAST* packets. So sending a broadcast ARP, it sees, a specific reply,
it doesn't see.
Checked the Receiver Control Register on the ethernet chip and it is set to
receive broadcast, multicast, and short packets. (there doesn't seem to be
a bit for accepting packets addressed to it)
Its an interesting clue however and one I'm pursuing.
