SES device of managed PCIe switch will be enumerated same as NVMe drives.
The device info type for this SES device is
MPI26_PCIE_DEVINFO_SCSI (0x4),
whereas the device info type for NVMe drives is
MPI26_PCIE_DEVINFO_NVME (0x3).
Based on this device info type driver determines whether the device is NVMe
drive or a SES device of a managed PCIe switch.
This SES device doesn't have the PCIe device page 2 information like NVMe
drives, so driver won't read PCIe device page 2 information for SES device.
This SES device uses only IEEE SGL's, So driver build's IEEE SGL's whenever
it receives any SCSI commands for this SES device.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
