libata sysfs attributes cannot be used for libsas-managed SATA devices because the ata_port location is different for libsas. Defined sysfs attributes (visible for SATA devices only): - /sys/block/sda/device/ncq_prio_enable - /sys/block/sda/device/ncq_prio_supported The newly defined attributes will pass the correct ata_port to libata helper functions.
