ibv_rate_to_mult (3)

Name

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

Synopsis

#include <infiniband/verbs.h>

int ibv_rate_to_mult(enum ibv_rate rate);

enum ibv_rate mult_to_ibv_rate(int mult);

Description

Libibverbs Programmer's Manual                             IBV_RATE_TO_MULT(3)



NAME
       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

SYNOPSIS
       #include <infiniband/verbs.h>

       int ibv_rate_to_mult(enum ibv_rate rate);

       enum ibv_rate mult_to_ibv_rate(int mult);

DESCRIPTION
       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.

RETURN VALUE
       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 trans-
       mission rate.
