So I'm back to this problem. A quick run down of what the original problem was:
I have a machine that I'm configuring to use kickstart to setup. It has two builtin ethernet ports (labeled ports 1 and 2) and I'm adding a third one on its PCIe bus. Originally I was using an r8169 clone a default kickstart always put it as eth0 with the builtin ones as eth1 and eth2 respectively. After some fiddling with blacklisting the driver during the kickstart process, I was able to get the machine to boot up with the r8169 as eth3 (!!!) while the other two were correctly identified as eth0 and eth1 (this is what I want except the PCIe card should've been eth2 but it never came up that way)
However I ran into other issues with the r8169 driver and ultimately replaced it for an IntelPRO, which happens to use the same e1000e module as the builtin ones. Great. Except ...
Now when I kickstart the machine, I get this: builtin port1 -> eth0 PCIe card -> eth1 builtin port2 -> eth2
What I want is: builtin port1 -> eth0 builtin port2 -> eth1 PCIe card -> eth2
I should also point out here that when PXE kicks in on this machine, the machine correctly enumerates the ethernet devices as port1, port2 and then the PCIe card. So somewhere in the kickstart process things change.
So I'm back to trying to figure out how to achieve this.
