Not sure what PORT is but you can start OpenSM on a specific port by
using the -g (or -guid) option. Something like:
opensm -g=0x12345678 where 0x12345678 is the port (not node) GUID

IPoIB won't work until the ports are brought up by the SM. Not sure
about the duplicated MACs. I don't understand this.
