libsas and ipr pass flags to ata_host_init that are meant for the port.
ata_host flags:
ATA_HOST_SIMPLEX = (1 << 0), /* Host is simplex, one DMA
channel per host only */
ATA_HOST_STARTED = (1 << 1), /* Host started */
ATA_HOST_PARALLEL_SCAN = (1 << 2), /* Ports on this host can be
scanned in parallel */
ATA_HOST_IGNORE_ATA = (1 << 3), /* Ignore ATA devices on this
host. */
flags passed by libsas:
ATA_FLAG_SATA = (1 << 1),
ATA_FLAG_PIO_DMA = (1 << 7), /* PIO cmds via DMA */
ATA_FLAG_NCQ = (1 << 10), /* host supports NCQ */
The only one that aliases is ATA_HOST_STARTED which is a 'don't care' in
the libsas and ipr cases since ata_hosts from these sources are not
registered with libata.
