Hi,
I have a lenovo x220 with a Intel 82579LM Gigabit Network Card. I am
also stuck with the e1000e driver. I use rtai with a 2.6.35 kernel
version on ubuntu 12.04.
I remember (not totally sure about this) that when I installed ubuntu on
the system, I had to download the ethernet driver from Intel because the
one provided by Ubuntu didn't work. Now I would like to use the patched
driver from the etherlab project, but I have problems. The patch was
provided by Juergen Kunz:

This is my dmseg output when I restart the ethercat service with
/etc/init.d/ethercat restart

It seems as if the driver loads well. The lspci -v command gives me:
00:19.0 Ethernet controller: Intel Corporation 82579LM Gigabit

Is it right that is says e1000e in the last line instead of ec_e1000e?
With my Beckhoff Ek1100 bus couple module connected to the network card
I get the following output for the command: /opt/etherlab/bin/ethercat

Interestingly I saw in the lsmod list that the patched driver ec_e1000e
has a size of 149498, while the e1000e is bigger by 32%: 198797.
Do we need a new driver patch, or does anyone see another issue here?
