Hey again,
I figured out that one can actually use RTnet without changing the ethernet
frame by simply no loading rtmac module. From what I have read in
README.rtmac, as long as rtmac.ko is not loaded the ethernet frame should
not change.
However, after compiling, installing and loading the modules rtnet,
rtpacket, rtipv4, and rt_e1000 I got the problem that dmesg showed
[ 146.489750]

(I use a intel pro/1000 MT Quad Port Server Adapter)
I guess this is the problem why rtifconfig rteth0 up 192.168.2.1 fails with
"ioctl: No such device".
Also, I noticed that the "./confgure" option -enable-rtmac=no had no impact
since it still was build. What am I doing wrong here ?
I really appreciate any kind of help !!
