NAME
       umad_get_issm_path - get path of issm device

SYNOPSIS
       #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 set-
       ting/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.

RETURN VALUE
       umad_open_port() returns 0 on success and a negative value on error as
       follows:
	-ENODEV IB device can´t be resolved
	-EINVAL port is not valid (bad portnum or no umad device)
