Hi Ben

The patch try to start scanning the ports from i=1 rather then i=0.

status = osm_vendor_get_all_port_attr(p_osm->p_vendor, attr_array,
&num_ports );

But this function to return the port attributes of all available ports does
not use the "port number" as index into the returned array of port
attributes. It simply starts with i=0 and adds on to it. The port numbers
are available in the attributes struct.
