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. SEE ALSO
