Here is that file:

# Marvell Technology Group Ltd. 88E8001 Gigabit Ethernet Controller
DEVICE=eth0
HWADDR=XX:XX:XX:XX:XX:XX   <-- hidden by me
ONBOOT=no
IPV6INIT=no
IPV6_AUTOCONF=no

I added the last two lines yesterday as part of
the disabling of ipv6 which seems to be causing
so many others network problems.

Except for the last two lines, this is what
the system defaulted to after intallation of F10.
I actually don't recall doing anything about networking
during the installation.  I think NetworkManager
is "taking care of things" for me.  This is my first
experience with NM.  (I usually hand edit
ifcfg-eth0 on mh other systems.)

Right after installation I was able to yum update w/o 
a problem.  But Firefox would not resolve names.
After googling, I learned that I needed to disable
ipv6.  Having done that, Firefox started working,
and I didn't seem to have any other network problems.

Then I tried to install the rpmfusion stuff and
the current problem began.
