I tried that:

bash-4.1# ibdiagnet -i mlx4_0 -p 2
Loading IBDIAGNET from: /usr/lib64/ibdiagnet1.5.7

-E- Illegal argument: Illegal value for -i option: mlx4_0
    (Legal value: a positive integer number).
    Exiting.

SYNOPSYS
  ibdiagnet [-c <count>] [-v] [-r] [-u] [-o <out-dir>]
     [-t <topo-file>] [-s <sys-name>] [-i <dev-index>] [-p <port-num>] [-wt]
     [-pm] [-pc] [-P <<PM>=<Value>>]
     [-lw <1x|4x|12x>] [-ls <2.5|5|10>]
     [-skip <ibdiag check>] [-load_db <db_file>] [-csv] [-vlr]

This is with the RHEL 6 ibutils.

bash-4.1# rpm -qf `which ibdiagnet`
ibutils-1.5.7-6.el6.x86_64

Perhaps there is a bug?
