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.
