       int umad_get_issm_path(char *ca_name, int portnum,char*path,intmax);

DESCRIPTION

       umad_get_issm_path()  resolves path to issm device (which used for setting/clearing PortInfo:CapMask IsSM
       bit) for portnum of the IB device ca_name , it stores resolved path in path array which cannot exceed max
       bytes in length (including NULL terminator).
       Opening issm device sets PortInfo:CapMask IsSM bit and closing clears it.

        -ENODEV IB device can´t be resolved
        -EINVAL port is not valid (bad portnum or no umad device)
