.SH NAME
.PP
ibv_rate_to_mult - convert IB rate enumeration to multiplier of 2.5
Gbit/sec
.PP
mult_to_ibv_rate - convert multiplier of 2.5 Gbit/sec to an IB rate
enumeration
.SH SYNOPSIS
.IP
.nf
\f[C]
#include <infiniband/verbs.h>

int ibv_rate_to_mult(enum ibv_rate rate);

enum ibv_rate mult_to_ibv_rate(int mult);
\f[R]
.fi
.SH DESCRIPTION
.PP
\f[B]ibv_rate_to_mult()\f[R] converts the IB transmission rate
enumeration \f[I]rate\f[R] to a multiple of 2.5 Gbit/sec (the base
rate).
For example, if \f[I]rate\f[R] is \f[B]IBV_RATE_5_GBPS\f[R], the value 2
will be returned (5 Gbit/sec = 2 * 2.5 Gbit/sec).
.PP
\f[B]mult_to_ibv_rate()\f[R] converts the multiplier value (of 2.5
Gbit/sec) \f[I]mult\f[R] to an IB transmission rate enumeration.
For example, if \f[I]mult\f[R] is 2, the rate enumeration
\f[B]IBV_RATE_5_GBPS\f[R] will be returned.
.SH RETURN VALUE
.PP
\f[B]ibv_rate_to_mult()\f[R] returns the multiplier of the base rate 2.5
Gbit/sec.
.PP
\f[B]mult_to_ibv_rate()\f[R] returns the enumeration representing the IB
transmission rate.
