This patchset adds 2 forms of interrupt aggregation support to the driver: - Interrupt converge: Interrupts from all completion queues can be reported through completion queue #0 interrupt only. - Interrupt coalesce: Ability to set timeout period at which we report completions on that queue (as an interrupt). The HW report completion interrupt as either happens: - configurable threshold of completions occur - a timeout, so we don't pend indefinitely until the threshold is reached There is also 2 minor patches to fix some register setting and also rearrange some code for proper condition checking.
