Procedure for changing ethernet controllers

[Alex]

Hi,

I have an fc17 system in which I've had to change the ethernet
controller from an e1000e card to what I believe is an rtl81391`2. I
recall changing the 70-persistent-net udev config file, but that
appears to no longer exist on my fc17 system.

What is the proper procedure for detecting, initializing, and
reconfiguring the system to use my new card?

I believe I'll also had to use dracut to recreate the initrd. I will
also need to detect for sure which driver the new ethernet controller
uses.

Thanks,
Alex
