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. .SH "SEE ALSO" .BR ibv_query_port (3) .SH "AUTHORS" .TP Dotan Barak <dotanb@mellanox.co.il>
