The 'hw.mfi.allow_cam_disk_passthrough' tunable does not seem to be 
recognised if I add it to my /boot/device.hints file (this is on FreeBSD 
10.3 with PERC 5/i controller). If I try to use sysctl to enable it, I get 
the error message:

 	sysctl: unknown oid 'hw.mfi.allow_cam_disk_passthrough'

Am I doing something wrong?
