Review of the eq coalescing logic showed the code was a bit fragmented. Sometimes it would save/set via an interrupt max value, while in others it would do so via a usdelay. There were also two places changing eq delay, one place that issued mailbox commands, and another that changed via register writes if supported. Clean this up by: - Standardizing the operation of lpfc_modify_hba_eq_delay() routine so that it is always told of a us delay to impose. The routine then chooses the best way to set that - via register or via mbx. - Rather than two value types stored in eq->q_mode (usdelay if chng via register, imax if change via mbox) - q_mode always contains usdelay. Before any value change, old vs new value is compared and only if different is a change done. - Revised the dmult calculation. dmult is not set based on overall imax divided by hardware queues - instead imax applies to a single cpu and the value will be replicated to all cpus.
