The rtnet rt_e1000e module does not implement the 'cards' parameter.  I have 
attached a patch for the 'next' branch of xenomai-3.git that adds this 
parameter, and it seems to work fine on my hardware.  The code was ported 
straight from the rt_e1000 module.  My machine has two e1000e cards, so this is 
a useful feature for me.  (I actually applied the same fix to the standard 
e1000e driver, which is even more useful to me, but I know it would be a 
maintenance nightmare for Xenomai to start maintaining that sort of patching...)

I am trying to learn rtnet, but it seems that the code from the rtnet git repo 
won't compile with linux-3.14.17/xenomai-2.6.4.  I saw that Gilles has pulled 
the rtnet code into the Xenomai-3 git repo, so it seemed to me that beta 
testing the Xenomai-3 rtnet code would be a better use of my time than messing 
with the old code base.  So far, so good.  My machine's primary ethernet 
interface is using the standard linux e1000e driver, and the secondary ethernet 
interface is up and running under rtnet using the rt_e1000e driver.  I can use 
rtping to talk to another linux box that is connected via a switch, provided I 
ping in the reverse direction first to set up the route information.
