Dear you, Do you means if the NIC replaced with a new one ( hardware fail ) or need to be installed the second NIC to the motherboard, the system ( such as FC9 ) will auto update the current NIC config and driver ( IP address by manual ) , right ? So, we needn't to running any tool ( cmd ) to update udev / modprobe ( system default ) ? Thnaks !
