Possible to have loopback + "real" network interface?

[Sebastian Huber]

Hello Nick,

the loopback interface is always there (on old RTEMS versions this is a 
different story).  You can configure a list of interfaces in 
rtems_bsdnet_ifconfig.  The actual interface configuration depends on your BSP.

What you want is kqueue(2).
