enum ibv_rate mult_to_ibv_rate(int mult);enum ibv_rate mult_to_ibv_rate(int mult); Description mult_to_ibv_rate() converts a multiplier value of 2.5 Gbit/sec to an InfiniBand transmission rate enumeration value. For example, if mult is 2, the rate enumeration IBV_RATE_5_GBPS will be returned. Parameters Name Direction Description...
int ibv_rate_to_mult(enum ibv_rate rate);int ibv_rate_to_mult(enum ibv_rate rate); Description ibv_rate_to_mult() converts an InfiniBand transmission enumeration rate to a multiple of 2.5 Gbit/sec (the base rate). For example, if rate is IBV_RATE_5_GBPS, the value 2 will be returned (5 Gbit/sec = 2...
int ibv_detach_mcast(struct ibv_qp *qp, const union ibv_gid *gid, uint16_t lid);int ibv_detach_mcast(struct ibv_qp *qp, const union ibv_gid *gid, uint16_t lid); Description ibv_detach_mcast() detaches a Queue Pair from a multicast group. After the detachment completes, this QP won't get a copy of...
