NAME

6       ibv_rate_to_mult - convert IB rate enumeration to multiplier of 2.5 Gbit/sec
7       ibv_mult_to_rate - convert multiplier of 2.5 Gbit/sec to an IB rate enumeration

SYNOPSIS

10       #include <infiniband/verbs.h>
11
12       int ibv_rate_to_mult(enum ibv_rate rate);
13       enum ibv_rate mult_to_ibv_rate(int mult);
14

DESCRIPTION

16       ibv_rate_to_mult()  converts  the IB transmission rate enumeration rate
17       to a multiple of 2.5 Gbit/sec (the base rate). For example, if rate  is
18       IBV_RATE_5_GBPS,  the  value  2  will be returned (5 Gbit/sec = 2 * 2.5
19       Gbit/sec).
20
21       mult_to_ibv_rate() converts the multiplier value (of 2.5 Gbit/sec) mult
22       to  an IB transmission rate enumeration. For example, if mult is 2, the
23       rate enumeration IBV_RATE_5_GBPS will be returned.
24

RETURN VALUE

26       ibv_rate_to_mult()  returns  the  multiplier  of  the  base  rate   2.5
27       Gbit/sec.
28
29       mult_to_ibv_rate()  returns  the enumeration representing the IB trans‐
30       mission rate.
