Hello all,
i have succesfully installed Xenomai 3.0.5 with linux 4.9.90, but I am having
trouble installing RTnet on an i218-lm.
I would always recommend using the latest version when trying something
new, both for Xenomai and the kernel. But in this case...
I followed these steps:
1) ifconfig eth0 down
2) rmmod e1000e
3) configured /usr/xenomai/etc/rtnet.conf according to
https://gitlab.denx.de/Xenomai/xenomai/-/wikis/RTnet
4) modprobe rtpacket
5) modprobe rtnet
6) modprobe rt_e1000e
But now if I try to run rtnet with ./rtnet start I get the following errors:
ioctl: No such device
ioctl: No such device
ioctl: No such device
ioctl: No such device
ioctl (add): No such device

./rtifconfig only show the local loopback but not rteth0
Dmesg shows that rtnet and the driver are being loaded

But with lspci -knn it shows that the NIC doesn't pick up the real time driver:

Kernel modules: e1000e
Did I do something wrong or is my I219-LM NIC not supported by RTnet?
...it won't help as that NIC is not supported. There was some update of
the driver shared a while ago, but I'm also not sure if that would have
helped - it was using an old kernel as baseline, too.
