.SH "NAME"
.nf
ibv_rate_to_mult \- convert IB rate enumeration to multiplier of 2.5 Gbit/sec
.sp
mult_to_ibv_rate \- convert multiplier of 2.5 Gbit/sec to an IB rate enumeration
.SH "SYNOPSIS"
.nf
.B #include <infiniband/verbs.h>

.SH "DESCRIPTION"
.B ibv_rate_to_mult()
converts the IB transmission rate enumeration
.I rate
to a multiple of 2.5 Gbit/sec (the base rate). For example, if
.I rate
is
.BR IBV_RATE_5_GBPS\fR,
the value 2 will be returned (5 Gbit/sec = 2 * 2.5 Gbit/sec).
.PP
.B mult_to_ibv_rate()
converts the multiplier value (of 2.5 Gbit/sec)
.I mult
to an IB transmission rate enumeration. For example, if
.I mult
is 2, the rate enumeration
.BR IBV_RATE_5_GBPS
will be returned.
.SH "RETURN VALUE"
.B
ibv_rate_to_mult()
returns the multiplier of the base rate 2.5 Gbit/sec.
.PP
.B mult_to_ibv_rate()
returns the enumeration representing the IB transmission rate.
