Dear All,   I am trying to set up RTNET using the latest xenomai_3.2.1 on an x86_64 system. I need only the raw packet (e.g rtpacket layer). I tried a lot of things but I still got errors like:  ioctl: Inappropriate ioctl for device    I try to use this PCI device: 
01:00.0 Ethernet controller: Intel Corporation 82576 Gigabit Network Connection (rev 01)
    Subsystem: Intel Corporation Gigabit ET Dual Port Server Adapter
    Kernel driver in use: rt_igb
    Kernel modules: igb, rt_igb   What I do is: ifconfig enp1s0f0 down
ifconfig enp1s0f1 down
rmmod igbmodprobe rtnet
modprobe rtpacket
modprobe rt_igb
modprobe rtipv4
modprobe rtudp  set up the rtnet.conf file and start rtnet: /usr/xenomai/sbin$ sudo ./rtnet start
