Ok, that's probably because the driver doesn't correctly set up the
sysfs device links for the relationship between the device and it's
parents.  That's a driver bug.  If it did do this, NetworkManager would
likely just see the device and handle it like you'd expect.

Can you provide the output of:

ls -al /sys/class/net/ib0/

and:

ls -al /sys/class/net/ib0/device/

Can you send the device any sorts of commands, and if so, what sort of
commands?
