Yes, I have enabled RTDM and RTNET in kernel confirm as loadable module (M), and rent drivers are loaded successfully. As I said before, all the rtnet modules are visible from lsmod. Also, as I said rtnet loopback (rtlo) is working fine. But rteth0 does not come up using rent script. I even tried forcefully reserving the interface name to (eth0, eth1) by passing kernel command line argument. Now the interface name is shown as : eth0, eth1 (instead of enp0*) But still I am not able to get rteth0, rteth1 interface. Is there any thing I am missing?
