626 /* Calculate the EQ size
627 * ---------------------
628 * Each ICID may generate up to one event at a time i.e.
629 * the event must be handled/cleared before a new one
630 * can be generated. We calculate the sum of events per
631 * protocol and create an EQ deep enough to handle the
633 * - Core - according to SPQ.
634 * - RoCE - per QP there are a couple of ICIDs, one
635 * responder and one requester, each can
636 * generate an EQE => n_eqes_qp = 2 * n_qp.
637 * Each CQ can generate an EQE. There are 2 CQs
638 * per QP => n_eqes_cq = 2 * n_qp.
639 * Hence the RoCE total is 4 * n_qp or
641 * - ENet - There can be up to two events per VF. One
642 * for VF-PF channel and another for VF FLR
643 * initial cleanup. The number of VFs is
644 * bounded by MAX_NUM_VFS_BB, and is much
645 * smaller than RoCE's so we avoid exact
