No.  The very first segment sits in the request IU (e.g., the COMMAND IU in
SOP), which only contains a standard SGL segment, which has an array of
16-byte SGL descriptors.
That array might just have one 16-byte Last Alternative SGL Segment
descriptor pointing to the alternative SGL segment (which is the type of SGL
segment that has the 20-byte descriptors).

Marvell has a question about PQI.
Regarding Alternative SGL Segment in the PQI Spec, Annex A - Can the very
first segment be an Alternative SGL Segment?
Thanks,
