1. An apparatus, including: a lane number first-in first-out buffer (FIFO) array in a serial-attached small computer system interface (SCSI)-serial SCSI protocol (SAS-SSP) device, the FIFO array organized into a plurality of FIFOs, each FIFO to store a sequence of lane numbers, the sequence representative of an input-output (IO) stream subset of a plurality of SAS-SSP frames received at a plurality of lane receive buffers, wherein a first lane number stored at a first position within a first FIFO is associated with a first frame from the IO stream subset stored in a first lane receive buffer corresponding to the first lane number; and an IO tag look-up table (LUT) coupled to the FIFO array to store a first IO tag associated with the IO stream subset and to index the first FIFO from the FIFO array using the first IO tag.
