[SCSI] scsi_transport_sas: make minimum and maximum linkrate settable quantities
According to SPEC, the minimum_linkrate and maximum_linkrate should be settable by the user. This patch introduces a callback that allows the sas class to pass these settings on to the driver. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
