Mellanox -- can you follow up on this?

Also, in addition to the patches I provided for selecting an arbitrary GID (I was planning on committing them when Mike tested them at Purdue, but perhaps I should just commit to the trunk anyway), perhaps we should check if a non-default SL is supplied via MCA param in the RoCE case and output an orte_show_help to warn that it will have no effect (i.e., principle of least surprise and all that).
