Works?
First I have to say that the machine running Fedora 21 is not connected
to network (since Agere Et-131x is the only network card). From my
understanding commands like "yum install ..." or "wget ..." will not run
on that machine without network connectivity. Therefore I installed a
Fedora 21 into a virtualbox on my Win 7 and followed the steps you
described there:
It went fine until the "cp et131x.ko /lib/modules/$(uname -r)/updates"
command. When reaching that step I did transfer the et131x.ko via USB
stick to the target machine. There I did continue with the procedure you
described.
When running "modprobe -v et131x" on the target machine it failed with
the following message:
sudo modprobe -v et131x
insmod /lib/modules/3.17.4-301.fc21.i686/updates/et131x.ko
modprobe: ERROR: could not insert 'et131x': Exec format error
To get some more information I then ran "file" and "uname" commands:
file /lib/modules/3.17.4-301.fc21.i686/updates/et131x.ko
/lib/modules/3.17.4-301.fc21.i686/updates/et131x.ko: ELF 32-bit LSB
relocatable, Intel 80386, version 1 (SYSV),
BuildID[sha1]=fa9fe5876be08f1c23a9873e78460196bc67effb, not stripped

19:32:52 UTC 2014 i686 i686 i386 GNU/Linux
On the machine where I built the et131x.ko file I also ran "uname" command:
uname -a
Linux thebuilder.localdomain 3.18.7-200.fc21.i686 #1 SMP Wed Feb 11
22:26:31 UTC 2015 i686 i686 i386 GNU/Linux
I installed it from the same installation media but unfortunately ran
"yum update" before building the et131x.ko file. So the kernel versions
on the two machines differ. Before following your recipe I started
building a custom kernel, so I have some ~/rpmbuild directory, perhaps
this does in some way conflict with your description.
Whenever you used "su" command in your description I used "sudo"
command, I hope that this will not lead to problems.
I'm not sure if it is valid to build the et131x.ko file on another
machine, so I'll try to find an USB-Ethernet-Card to bring the target
machine to the network and then again run thoses steps you described
directly on the target machine.
Thanks,
Meikel
