umad_set_addr - set MAD address fields within umad buffer using host ordering
SYNOPSIS
#include <infiniband/umad.h>
int umad_set_addr(void *umad, int dlid, int dqp, int sl, int qkey);
DESCRIPTION
umad_set_addr() sets the MAD address fields within the specified umad buffer using the provided host ordered fields. dlid is the destina-
tion LID. dqp is the destination QP (queue pair). sl is the SL (service level). qkey is the Q_Key (queue key).
RETURN VALUE
umad_set_addr() returns 0 on success, and a negative value on errors. Currently, there are no errors indicated.

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.
