I've noticed that polling support for the vr device can not be 
controlled or displayed from ifconfig (Unlike in FreeBSD). Adding the 
following seems to enable that support. No guarantees on correctness but 
maybe someone else can take a look.

After the modifications with DEVICE_POLLING kernel support and 
kern.polling.enable=1.

ifconfig vr0
