Reinstate installation of igb_uio
For good performance on some platforms, we need the igb_uio driver. With this change, the driver is compiled and insmod done during boot time. When running the rapid scripts, the devbind.sh script is sent to the instances (after replacing the string "MACADDRESS"). Make sure you uncomment the proper line to chose which driver you want to use. Change-Id: I69549400a97f29e06add6ab44515e96ffa9ce0e8 Signed-off-by: Luc Provoost <luc.provoost@intel.com>
