For a long time we have used Intel PT (Intel® 82572GI Gigabit Controller) nic in our routers, but now, Intel does not produces this model any more. So we have to switch to new one, but:
Intel 1000 CT (Intel® 82574L Gigabit Ethernet Controller) nic is not supported by ROS.
Driver update would be nice 
generate supout.rif and send it to support@mikrotik.com
