Hi,

I have a host with two identical ethernet devices (Intel 82573L).
Both devices work great with the e1000e module, and with the rt_e1000e
module.  I would like to use the first ethernet device with the e1000e
module to connect to the LAN, and the second ethernet device with the
rt_e1000e module to communicate with an EtherCAT slave.

The problem I run into is that when I load the e1000e module, the
kernel logs show that it detects and registers both ethernet devices.
But when I load the rt_e1000e module after that, the kernel logs show
that it does not detect any devices any more.   When I swap the order,
and first load the rt_e1000e module, it detects and registers both
ethernet devices, but then the e1000e module can't find any devices
any more.  So pretty much, whichever module I load first claims both
devices.  This behavior is confirmed by both the kernel logs and by
running (rt_)ifconfig.

Is there a way to limit a module to a single device at load time, so
it would not claim both devices at once? Or should I be looking at a
different type of solution? Any help is appreciated!

Thanks,
Wim
