UMAD_REGISTER_OUI(3)					    OpenIB Programmer's Manual					      UMAD_REGISTER_OUI(3)

NAME

       umad_register_oui - register the specified class in vendor range 2 for port

SYNOPSIS

       #include <infiniband/umad.h>

       int umad_register_oui(int portid, int mgmt_class, uint8_t rmpp_version, uint8_t oui[3], uint32_t method_mask[4]);

DESCRIPTION

       umad_register_oui()  registers the specified class in vendor range 2, the specified oui, and whether RMPP is being used for the port speci-
       fied by the portid handle. If method_mask array is provided, the caller is registered as a replier (server) for the  methods  having  their
       corresponding  bit  on  in  the	method_mask.   If  method_mask is NULL, the caller is registered as a MAD client, meaning that it can only
       receive replies on MADs that it sent (solicited MADs).

RETURN VALUE

       umad_register() returns non-negative agent id number on success, and a negative value on error as follows:
	-EINVAL invalid port handle or class is not in the vendor class 2 range
	-EPERM	registration failed

UMAD_SET_GRH_NET(3)					    OpenIB Programmer's Manual					       UMAD_SET_GRH_NET(3)

NAME

       umad_set_grh_net - set GRH fields within umad buffer using network ordering

SYNOPSIS

       #include <infiniband/umad.h>

       int umad_set_grh_net(void *umad, void *mad_addr);

DESCRIPTION

       umad_set_grh_net()  sets  the GRH fields (grh_present, gid, hop_limit, traffic_class, flow_label) within the specified umad buffer based on
       the mad_addr supplied. The provided mad_addr fields are expected to be in network order.  If the mad_addr pointer supplied is NULL, no  GRH
       is  set.   The  argument  mad_addr  is  a  pointer to an ib_mad_addr_t struct, as specified in <infiniband/umad.h>.  The argument umad is a
       pointer to an ib_user_mad_t struct, as specified in <infiniband/umad.h>.

       typedef struct ib_mad_addr {
	       uint32_t qpn;
	       uint32_t qkey;
	       uint16_t lid;
	       uint8_t	sl;
	       uint8_t	path_bits;
	       uint8_t	grh_present;
	       uint8_t	gid_index;
	       uint8_t	hop_limit;
	       uint8_t	traffic_class;
	       uint8_t	gid[16];
	       uint32_t flow_label;
       } ib_mad_addr_t;

       typedef struct ib_user_mad {
	       uint32_t agent_id;
	       uint32_t status;
	       uint32_t timeout_ms;
	       uint32_t retries;
	       uint32_t length;
	       ib_mad_addr_t addr;
	       uint8_t	data[0];
       } ib_user_mad_t;

RETURN VALUE

       umad_set_grh_net() returns 0 on success, and a negative value on errors. Currently, there are no errors indicated.

KNOWN BUGS

       Not implemented.
