NAME

       umad_get_ca, umad_release_ca - get and release InfiniBand device port attributes

SYNOPSIS

       #include <infiniband/umad.h>

       int umad_get_ca(char *ca_name, umad_ca_t *ca);
       int umad_release_ca(umad_ca_t *ca);

DESCRIPTION

       umad_get_ca()  gets the attributes of the InfiniBand device ca_name.  It fills the ca structure with the device attributes specified by the
       ca_name or with the default device attributes if ca_name is NULL.  umad_release_ca() should be called before the ca  structure  is  deallo-
       cated.  The argument ca is an umad_ca_t struct, as specified in <infiniband/umad.h>.

       typedef struct umad_ca {
	       char ca_name[UMAD_CA_NAME_LEN];		       /* Name of the device */
	       uint node_type;				       /* Type of the device */
	       int numports;				       /* Number of physical ports */
	       char fw_ver[20]; 			       /* FW version */
	       char ca_type[40];			       /* CA type (e.g. MT23108, etc.) */
	       char hw_ver[20]; 			       /* Hardware version */
	       uint64_t node_guid;			       /* Node GUID */
	       uint64_t system_guid;			       /* System image GUID */
	       umad_port_t *ports[UMAD_CA_MAX_PORTS];	       /* Array of device port properties */
       } umad_ca_t;

       umad_release_ca() releases the resources that were allocated in the function umad_get_ca().

RETURN VALUE

       umad_get_ca() and umad_release_ca() return 0 on success, and a negative value on error.

NAME

       umad_get_port, umad_release_port - open and close an InfiniBand port

SYNOPSIS

       #include <infiniband/umad.h>

       int umad_get_port(char *ca_name, int portnum, umad_port_t *port);
       int umad_release_port(umad_port_t *port);

DESCRIPTION

       umad_get_port()	fills  the port structure with the IB port attributes specified by ca_name and portnum , or the default port if ca_name is
       NULL and portnum is zero. If only one of ca_name and portnum are specified, the other is used as a filter.  For	example,  passing  a  NULL
       ca_name	and  2 for the portnum means get a port from any of the local IB devices, as long as it is the second port.  Note that the library
       may use some reference scheme to support port caching therefore umad_release_port() should be called before the port structure can be deal-
       located.  The argument port is an umad_port_t struct, as specified in <infiniband/umad.h>.

       typedef struct umad_port {
	       char ca_name[UMAD_CA_NAME_LEN];		       /* Name of the device */
	       int portnum;				       /* Physical port number */
	       uint base_lid;				       /* Base port LID */
	       uint lmc;				       /* LMC of LID */
	       uint sm_lid;				       /* SM LID */
	       uint sm_sl;				       /* SM service level */
	       uint state;				       /* Logical port state */
	       uint phys_state; 			       /* Physical port state */
	       uint rate;				       /* Port link bit rate */
	       uint64_t capmask;			       /* Port capabilities */
	       uint64_t gid_prefix;			       /* Gid prefix of this port */
	       uint64_t port_guid;			       /* GUID of this port */
       } umad_port_t;

       umad_release_port() releases the resources that were allocated by the umad_get_port() function for the specified IB port.

RETURN VALUE

       umad_get_port() and umad_release_port() return 0 on success, and a negative value on error.
