[SCSI] libsas: Add a sysfs knob to enable/disable a phy This patch lets a user arbitrarily enable or disable a phy via sysfs. Potential applications include shutting down a phy to replace one lane of wide port, and (more importantly) providing a method for the libata SATL to control the phy. Signed-off-by: Darrick J.
