[PATCH 3/4] mpt3sas: Add support for ATLAS PCIe switch.
From: Suganath Prabu S
Date: Tue Jan 29 2019 - 07:15:05 EST
Add Atlas PCIe Switch Management Port device PNPID,
Vendor Id: 0x1000
device Id: 0x00B2
This device is based on MPI 2.6 spec and it exposes one
SES device to accept management commands for the PCIe switch.
