    sata_mv: optimize IRQ coalescing for 8-port chips · 6abf4678
    Mark Lord authored
    Enable use of the "all ports" IRQ coalescing optimization
    for GEN_II / GEN_IIE chips that have dual host-controllers (8-ports).
    Currently only the 6081 chip qualifies, but other chips may come along someday.
    
    Rather than each half of the chip having to satisfy a local set of coalescing thresholds,
    use of this feature groups all ports together under a single set of thresholds.
