Mistake from when I still had my editor switched to spaces mode. I set it
to tab mode a little bit later and didn't think to go back and correct this.

It's not that it took a lot of effort, I just simply missed the space after
the comma. It still looks better :)

It's a habit -- I blame math from grade school years ago. I'll remove them
in the next version.

Looking at the header file, I really cannot find anything that would bear in
common with sample code from a book. If it was an actual driver file,
maybe. But a header file containing specific definitions for hardware bits?
I tracked down the first commit back in 2001 and put in the guy who
initially submitted it. Is there a better way to handle this? I doubt that
book had SGI O2 MACE Ethernet-specific defines in it.
