IBV_RATE_TO_MULT(3)     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
       transmission rate.
