IBV_RATE_TO_MULT(3) Libibverbs Programmer’s Manual IBV_RATE_TO_MULT(3)

ibv_rate_to_mult - convert IB rate enumeration to multiplier of 2.5 Gbit/sec

mult_to_ibv_rate - convert multiplier of 2.5 Gbit/sec to an IB rate enumeration

#include <infiniband/verbs.h>
int ibv_rate_to_mult(enum ibv_rate rate);
enum ibv_rate mult_to_ibv_rate(int mult);

ibv_rate_to_mult() converts the IB transmission rate 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 * 2.5 Gbit/sec).

mult_to_ibv_rate() converts the multiplier value (of 2.5 Gbit/sec) mult to an IB transmission rate enumeration. For example, if mult is 2, the rate enumeration IBV_RATE_5_GBPS will be returned.

ibv_rate_to_mult() returns the multiplier of the base rate 2.5 Gbit/sec.

mult_to_ibv_rate() returns the enumeration representing the IB transmission rate.
