Can you try the attached patch and see if it properly detects the failure
(at runtime) and takes proper action to use the ioctl?  You should see one
complaint in the logs about having to switch to ioctl, but after that it
should not complain if I wrote the code correctly.

		    error_msg = c_format("ERROR:  Settting interface status using netlink failed"
					 " on: %s.  Will try to use ioctl method instead.",
					 ifname.c_str());

This is compile tested only.

Thanks,
Ben
