Thank you for catching that, Newtor.
When I went to /etc/udev/rules.d I found there was NO file named network-devices.rules.
This is a list of files in that directory:
10-vl-hot.rules.disabled 60-pcmcia.rules 90-hal.rules
30-libgphoto2.rules 64-device-mapper.rules 99-fuse.rules
and I didn't see anything in any of them dealing with PCI or etfx. Actually, in the referenced post he does say "(NOTE: this is actually not provided by default)."
Searching the forum, I found 2 other mentions of this file. In one of them, the respondent says "so i just create the file
/etc/udev/rules.d/network-devices.rules and add this line in it (if i use only one of the two eths)" Of course, I'll put both lines in mine.
The only problem: I have no idea what to prefix the name with. I'll create the file without a prefix until I hear otherwise,
