I have added support for SIOCAIFADDR and SIOCDIFADDR ioctl calls to 
rtems_bsdnet_ifconfig function.
We have submitted this RTEMS patch about three months back. It should be 
in the latest snapshots.
Make sure that your snapshot has this support. Look in rtems_glue.c file 
for rtems_bsdnet_ifconfig() function.

 From you application  initialize ifaliasreq data structure with your 
interface information and  call  rtems_bsdnet_ifconfig(ifname, 
SIOCAIFADDR, &ifra).
Hope this helps.
