(IB_PATH_RECORD_RATE_2_5_GBS - 1) is defined as 1 and it's a reserved value
IBTA p917.
Moreover in the OpenSM code opensm/osm_sa_mcmember_record.c:288 the check is:

	if (rate_mgrp <= rate_required) { //equal or greater

So I guess rate here could be defined as:
	mc_req_rec.rate =
		(IB_PATH_RECORD_RATE_2_5_GBS) | IB_PATH_SELECTOR_GREATER_THAN << 6;
