       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.

       follows:
        -ENODEV IB device canĀ“t be resolved
        -EINVAL port is not valid (bad portnum or no umad device)
