Thank you for you reply,
I forgot to load the rtcfg module, i solved that problem. But i still can't
sniff the traffic with wireshark. I did load the rtcap right after the driver.
I can see the RTcap dmesg and also the rtping is responding slowly (i assume
RTcap adds some delay). But i still cant see the the rteth0 (or its mirror as
written in readme) with wireshark. If i understand this correctly after i load
the the RTcap module, the $ifconfig should show the mirror of the rteth0
interface? A pasted the module load order, tmesg and ifconfig reply below.
Regards,
Klemen

Does your RT-NIC work (rtifconfig etc.)? Then, rtcap has to be loaded
after that driver but before starting its interface via rtifconfig. The
rtnet start script implicitly documents the steps. And then there is
README.rtcap, of course.

insmod rtcfg? Again, the startup script can serve as a guide - or may
just work for you.
