Enclosed the patch for the "reset adapter" issue of the e1000e
driver for 3.2 kernel. It avoids continuously calling
e1000_reset_task when EtherCAT is used and link is down.<br>

Hello Gavin,<br>
<br>
thanks for the hint, I'll have a look for Florians patch and your
post. I applied Florians "Link detection" patch for e1000e driver
3.4 to the 3.2er driver (see attatchment), it solves the link
detection issue here.<br>
<br>
Regards,<br>

<p class="MsoNormal" style="margin-bottom:12.0pt">Hello
Daniel,<br>
<br>
I am using this combination for a while now, with 32- and
64-bit versions of the 3.2er Debian RT-Kernel. If there is
a EtherCAT device connected to the computer, the driver
works fine.<br>
There are two issues in this driver version, if there are
no EtherCAT devices connected. The first, the one you
mentioned here, is when the EtherCAT Master starts up with
no device connected, then the network-adapter is
continously reseted until a device is connected. It may
hang the computer if no device is connected for a while.<br>
The second issue is that when the link is plugged off, the
link state is not updated. Unfortunately, I did not have
time yet to correct these issues.<br>
<br>
Greetings,<br>
Jürgen Kunz<o:p></o:p></p>
