If there are no ARP entries on an ib<n> interface, I don't think it
would show up there. If you ping an explicit address on that ib<n>
subnet, you would see something like:
? (192.168.0.2) at <incomplete> on ib0

I presume you've modprobe'd ib_ipoib and ifconfig'd ib<n> to get it up
and running (ifconfig -a shows ib<n> in an UP state).
