Administrator intervention is currently required to get good numbers when switching from running latency tests to IOPS tests. The configured interrupt coalescing values will greatly effect the results of these tests. Currently, the driver has a single coalescing value set by values of the module attribute. This patch changes the driver to support auto-configuration of the coalescing value based on the total number of outstanding IOs and average number of CQEs processed per interrupt for an EQ. Values are checked every 5 seconds. The driver defaults to the automatic selection. Automatic selection can be disabled by the new lpfc_auto_imax module_parameter. Older hardware can only change interrupt coalescing by mailbox command. Newer hardware supports change via a register. The patch support both.
