       #include <infiniband/umad.h>

       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).
