in that tarball there is a readme file, have you read this? its giving directions that should be fairly easy, keep in mind in that file where it references a # its meaning this is the command line (terminal)
so if you open terminal it will say somthing to the effect of: (the words themselves would be different, structure should be the same)
CODE
mckooter@myserver:> _
(the _ being where you can start typing)
in the readme the # is being used to indicate where you start typing : i.e.
from the instructions it says
QUOTE
# rmmod r8169
note: If the built-in driver cannot removed by rmmod, please edit /etc/modprobe.conf and comment 'alias eth0 r8169'. Then, remove it again or reboot your computer.
on your terminal you would see
CODE
mckooter@myserver:> rmmod r8169
so they are telling you to run those commands manually
sorry if my above is confusing i really tried to make it easy, but who knows
